Consumption of mine water by wild ungulates in the sources of the Ussuri river, on the territory of the national park «Call of the tiger». Bulletin of the Tomsk Polytechnic University. Geo Аssets Engineering, 2023, vol. 334, no. 7, рр. 111-121. In Rus. The relevance of the study is determined by the need to clarify the reason for the use of mineralized water by wild animals, which is typical for many areas of the world. The new knowledge is closely related to the geophagy problem, the solution of which opens a wide prospect of fundamental research in the fields of landscape biogeochemistry, ecology and medicine. Purpose: to study chemical composition of the mineralized mine water in the lake located on the territory of the out-of-operation tin-polymetallic ores concentrator dump in the upper Ussuri river which is being consumed actively by wild ungulates; to reveal number of animal visitors to the lake during an annual cycle; to reveal the reason of mine water consumption. Objects: ungulates visiting the lake with mine water; lake water and bottom sediments. Methods: estimation of visitation of the mine lake by animals by means of photographic traps; chemical composition determination: inductively coupled plasma mass spectrometry (ICP-MS) (Agilent 7700x spectrometer, Agilent Techn., USA); atomic emission spectrometry (spectrometer iCAP 7600 Duo); ion chromatography (LC-20 ion-liquid chromatograph, Shimadzu, Japan). Results. It was revealed that animals come to the lake uniformly throughout the year, except for the winter period, when the water is covered by a thick layer of ice. In high concentrations trace elements were found, including both elements with high toxicity (Cd and Pb) exceeding MAC for drinking water from 20 to 80 times and essential elements such as Fe, Mn, Cu, Zn, Co, Cr, Ni, Se, Li, which concentration either does not exceed MPC or exceeds it insignificantly. The concentration of REE, especially of the light subgroup, is also very high. The reason for mine water consumption by animals, most likely, is the high concentration of rare-earth elements of the light subgroup in it.

Emergency of electric complex of outgoing transmission lines is associated with the occurrence of damage to the line isolation and the resulting transients, marked by the presence of higher harmonic components of currents and voltage, which reduce the reliability and energy efficiency of electrical equipment of oil and gas companies: degrade the mechanical characteristics and efficiency of electric motors, accelerate aging of their isolation, disrupt the operation of control systems and emergency automatics, fault diagnostics systems.

In the oil and gas industry, one-dimensional mechanical earth models are used to analyze wellbore stability, to design hydraulic fracturing, to assess the probability of sand production with oil and gas flow, and as input data for three-dimensional mechanical earth models. One-dimensional mechanical earth models are very demanding on the volume and quality of the initial data, for example, when calibrating the model to define the uniaxial compression strength and horizontal stresses, borehole imager data are required, which are usually not recorded in all wells and in whole interval.

Therefore, solving the problem of calibration of a one-dimensional mechanical earth model using more accessible caliper data is an urgent problem, the solution of which will allow building calibrated geomechanical models for a larger number of wells.

According to the ruling theory for organic origin of petroleum, geothermal regime is considered to be the main factor, which is responsible for realization of potential for oil generation. Therefore, it is not irrelevant to develop geothermics as a method of exploration geophysics for forecasting and evaluating oil and gas potential. Forecast tasks are reduced to detection local geothermal anomalies and establishing its relation to hydrocarbon deposits. This method may make a good showing while supplementary exploration in the territories with well-developed infrastructure and a large amount of wells as it is based on modelling and analysing of available data and does not propose additional field works. The main aim: establishing qualitative and quantitative relations between deep heat flow and oil and gas potential, also between gradient zones of heat flow and localization of hydrocarbon fields in the west of Tomsk Region. Objects: thermal field and oil and gas potential in the west of Tomsk Region. Subjects. The thermal field is described with such parameters as deep heat flow density and horizontal gradient of heat flow. Hydrocarbon fields are divided depending on fluid type into oil, oil-gas-condensate and gas-condensate. Methods. The deep heat flow was determined through paleotemperature modelling. The grid with cells of 20×20 km was set on study territory in increments of 10 km. Heat flow values were determined in the centers of each cell using Kriging interpolation method. The absolute horizontal gradient of heat flow was calculated on the same grid using five spot formula. Quantitative parameter of oil and gas potential – hydrocarbon density – was determined on the same grid. Quantitative relations were investigated by correlation and regression analysis. Relationships of heat flow density and horizontal gradient of heat flow with localization of hydrocarbon fields of different fluid type were detected by one-way ANOVA test. Results. The main results of this study are established distribution patterns for deposits of different fluid type in thermal field. Correlation analysis showed highly significant correlation coefficients. The conclusion. Oil and oil-gas-condensate fields tend to the average heat flow values (52 mW/m2), while gas-condensate are associated with high heat flow values (57 mW/m2).

Distribution of natural radionuclides in ashes, collected by thermal power plants electrostatic precipitator. Bulletin of the Tomsk Polytechnic University. Geo Аssets Engineering, 2023, vol. 334, no. 7, рр. 177-186. In Rus. Relevance. In the context of the global trend towards sustainable development, there is a problem of utilization of ash and slag waste from thermal power plants. The use of these wastes in the construction industry is of particular importance, due to the resource intensity of the production of building materials. Fly ash in the building materials composition can influence to a large extent the natural radioactivity of structures and increase the background radiation in the buildings. This is due to the fact that when coal combusting, fly ash is enriched with natural radionuclides. Purpose: to study the radioactivity of fly ash deposited on various fields of the electrostatic precipitator. Object: fly ash deposited on the fields of electrostatic precipitators from the combustion of Kansk-Achinsk brown coal in power boilers BKZ-420-140 PT-2. Methods. Content of Ra-226, Th-232 and K-40 was determined by gamma-spectrometric method, the value of the normalized indicator of specific effective activity for fly ash was calculated. The granulometric composition of the studied samples was determined by the method of laser diffraction analysis. Cluster analysis was used for statistical processing of test results. Results. The presence of two clusters in the content of natural radionuclides was established. In the first cluster, which has high radioactivity, the first and second fields of UGZ-4 electrostatic precipitators are combined, and in the second – the third and fourth fields. A correlation dependence was established between the numbers of fields of electrostatic precipitators, the size of ash particles, the content of Ra-226 and specific effective activity was established. No such dependence was found for Th-232. Conclusions. Particle distribution in the fields of electrostatic precipitators is multimodal. The nature of the distribution of each mode approaches the lognormal law. The content of radium and the value of the specific effective activity depend on the size of ash particles and are described by an exponential function. The highest content of Ra-226 is observed in the ashes deposited on the third and fourth fields of electrostatic precipitators, which indicates the enrichment of finer ash particles with this radionuclide.

Geo Аssets Engineering, 2023, vol. 334, no. 7, рр. 177-186. In Rus.\u0000Relevance. In the context of the global trend towards sustainable development, there is a problem of utilization of ash and slag waste from thermal power plants. The use of these wastes in the construction industry is of particular importance, due to the resource intensity of the production of building materials. Fly ash in the building materials composition can influence to a large extent the natural radioactivity of structures and increase the background radiation in the buildings. This is due to the fact that when coal combusting, fly ash is enriched with natural radionuclides. Purpose: to study the radioactivity of fly ash deposited on various fields of the electrostatic precipitator. Object: fly ash deposited on the fields of electrostatic precipitators from the combustion of Kansk-Achinsk brown coal in power boilers BKZ-420-140 PT-2. Methods. Content of Ra-226, Th-232 and K-40 was determined by gamma-spectrometric method, the value of the normalized indicator of specific effective activity for fly ash was calculated. The granulometric composition of the studied samples was determined by the method of laser diffraction analysis. Cluster analysis was used for statistical processing of test results. Results. The presence of two clusters in the content of natural radionuclides was established. In the first cluster, which has high radioactivity, the first and second fields of UGZ-4 electrostatic precipitators are combined, and in the second – the third and fourth fields. A correlation dependence was established between the numbers of fields of electrostatic precipitators, the size of ash particles, the content of Ra-226 and specific effective activity was established. No such dependence was found for Th-232. Conclusions. Particle distribution in the fields of electrostatic precipitators is multimodal. The nature of the distribution of each mode approaches the lognormal law. The content of radium and the value of the specific effective activity depend on the size of ash particles and are described by an exponential function. The highest content of Ra-226 is observed in the ashes deposited on the third and fourth fields of electrostatic precipitators, which indicates the enrichment of finer ash particles with this radionuclide. The conclusions obtained correspond to the well-known thesis about the increased radioactivity of ash particles that are not deposited by ash collection systems and enter the atmosphere together with flue gases.

Bulletin of the Tomsk Polytechnic University. Geo Аssets Engineering, 2023, vol. 334, no. 7, рр.17-25.In Rus. The relevance of the study is caused by the need to create a general methodology for determining the eccentricity of the inertia center of the core set cross-section, which will significantly reduce the irrational material and energy costs of drilling wells drilled in conditions of natural curvature of their trunks, as well as optimize the technical and economic indicators of drilling operations. Objective: to increase the productivity of geological exploration when working in conditions of natural curvature of boreholes. Objects: drilling well, column set, drilling shell, drill string, natural curvature of the borehole, the trajectory of the borehole. Methods: analysis of literature sources on the research topic; processing data of production organizations; graphoanalytic method. Results. To eliminate some of the shortcomings currently available in the issue of maintaining the trajectory of the borehole drilled in conditions of natural curvature, a general technique is proposed that ensures minimization of the deflecting force on the rock-breaking tool during the deepening. The proposed technique is divided into two components: the use of pre-deformed core sets; the creation of a direct precession with continuous contact of the half-wave crest with the well wall during rotation of the arrangement. To implement the first case, the paper presents a method for determining the value of residual or preliminary deformation of a rectilinear core pipe. Practically, the proposed technique is implemented by sequentially performing three basic operations: the plane of deformation of the core set is determined during drilling; the parameters of the core set are adjusted by its residual deformation by the calculated value; the well is drilled with a pre-deformed core set. To implement the second case, the paper presents a method for determining the magnitude of the eccentricity of the inertia center of the column set cross-section. In this case, in order to implement the method, it is necessary: to make a rational arrangement of the lower part of the drill string; to carry out the drilling process at the maximum possible rotation frequencies of the drill shaft; to use emulsion washing fluids; to reduce the amount of bending moment due to the operation of diamond crowns that work effectively at low axial forces. Both proposed methods are justified and supported by the results of experimental work. Conclusions. The conducted research allowed us to present and justify a fundamentally new method of reducing the curvature of boreholes based on the use of pre-deformed core sets, as well as to obtain a dependence for determining the optimal value of their residual

The relevance of the research is caused by the need to develop alternative and environmentally friendly energy sources in conditions of global warming. The development of geothermal energy will make it possible to produce thermal and electric energy without emissions of CO2 into the environment and reduce the dependence of the energy sector on hydrocarbon raw materials. The main aim of this study is a comprehensive analysis of the features of geothermal power plants, including the existing technologies for converting geothermal energy to provide consumers of electric and thermal energy. Objects: diagrams of geothermal power plants operating in different geographical and climatic conditions, as well as their working fluids. Methods: analytical review of thematic publications using the materials of the databases of the RSCI, Scopus and Web of Science, a comparative analysis of the effectiveness of geothermal power plants for various indicators. Results. Currently, there are about 400 geothermal power plants in the world. The active development of geothermal energy is caused by environmental friendliness, low cost of energy produced, minimal operating costs, lack of dependence on atmospheric influences, and the absence of the need to burn fuel, etc. At the same time, most of the world's geothermal power plants use the energy of a geothermal source with a water temperature of 100–200 °C. Among the main thermodynamic cycles and thermal schemes implemented, it is possible to single out direct cycle geothermal power plants with one-stage and two-stage separation of a geothermal source, with direct supply of dry steam to the turbine, binary and combined versions. The analysis shows that direct cycle geothermal power plants have the lowest cost of installed electrical power due to the relative simplicity and high thermal efficiency, but require high parameters of a geothermal source. On the other hand, binary geothermal power plants have the highest unit cost, but can be implemented on geothermal sources with relatively low water parameters, which was the main reason for their greatest spread in the world. At the same time, the implementation of a binary geothermal power plant with a Organic Rankine сycle has a number of advantages compared to the thermodynamic cycles of Kalina, Stirling and Brighton, among which the main ones are relative ease of adaptation and application, as well as low maintenance costs.

Bulletin of the Tomsk Polytechnic University. Geo Аssets Engineering, 2023, vol. 334, no. 7, рр. 164-176. In Rus. The relevance of the research is caused by the lack of knowledge on the behavior of rare metal in pegmatite ore formation in the Kalba region and the need to expand the rare-metal mineral resource base of the region and to establish geological and mineragenic mapping. The main aims of the research are identification of features of geotectonic development, geological structure and material composition of the rare-metal deposit Yubileynoe (Kalba region). Study area: large industrial rare metal deposit Yubileynoe and its mineral complexes.

Цель: изучение динамики мировых товарных потоков (производства, импорта, экспорта, потребления) конечных вольфрамовых продуктов (ферровольфрама, вольфрама металлического, карбида вольфрама); оценка критичности мирового рынка конечных вольфрамовых продуктов. Методы: статистический, графический, логический. Результаты. Мировой рынок конечных вольфрамовых продуктов достаточно сложный. Мировое производство конечных вольфрамовых продуктов выросло с 42–52 тыс. т W/год в 1970-х гг. до 100–119 тыс. т W/год в 1910-х гг. с темпом прироста за 50-летний период +2,2 %/год. В 1970–1980-е гг. был период обычного состояния медленно растущего мирового потребления конечных вольфрамовых продуктов с темпами прироста спроса на них +1,9 %/год. В 1990-е гг. – значительное сокращение спроса на конечные вольфрамовые продукты (–4,9 %/год) в военной сфере (завершение холодной войны) и сокращение роли России на вольфрамовом рынке (последствия стагнации российской экономики, в первую очередь, металлообработки). В 2000–2010-е гг. – бурный рост мирового спроса на конечные вольфрамовые товарные продукты, в первую очередь карбида вольфрама, ввиду экспоненциального наращивания возможностей китайской промышленности. Темпы прироста мирового спроса на конечные вольфрамовые продукты в этот период составили +6,7 %/год. Китай доминирует в мировом производстве, потреблении и торговле конечными вольфрамовыми продуктами, поэтому его торговая политика по сдерживанию (квотированию) экспорта этих товаров задает динамику мирового рынка вольфрама. К 2020 г. лидером производства конечных вольфрамовых продуктов является Китай: 68 % мирового предложения ферровольфрама, 57 % вольфрама металлического и 75 % карбида вольфрама. Большая часть этих товарных продуктов остается в Китае и идет на национальное потребление: 69 % мирового спроса на ферровольфрам, 53 % вольфрам металлический и 55% карбид вольфрама. Начиная с 1990 г. рынок мировой торговли вольфрамовыми продуктами перестает быть сырьевым, в нем начинают преобладать конечные вольфрамовые товары. Доли стоимости конечных вольфрамовых продуктов в мировой торговле суммы всех вольфрамовых продуктов составляли 20–30 % в 1970–1980-е гг., начали увеличиваться в 1989 г. превысив 50 % в 1993 г. и колеблется в диапазоне 45–65 % в 2000–2010-е гг. Главными экспортерами к настоящему времени являются: для ферровольфрама – Китай, для вольфрама металлического – Китай, США и Германия, для карбида вольфрама – Китай. Главные импортеры: для ферровольфрама – Германия, Япония, Нидерланды и Австрия, для вольфрама металлического – Германия и США, для карбида вольфрама – Германия, Япония и США. Большая часть
