Aiming at the problem of drill pipe washout in the SHYB583 well in Saudi Arabia, the failure mechanism of drill rod is studied by analyzing the physical and chemical properties of thickened transition zone, stress analysis of transition zone under the combined action of tension, bending and torsion, flow field characteristics of inner channel, dynamic characteristics and fatigue analysis of drill string under the condition of actual well trajectory. The results show that the thickness of some parts of the coating of the failed drill pipe sample does not meet the requirements of SY/T 0544-2010 technical conditions for internal coating of petroleum drill pipe (seriously thin), and the drill pipe material contains high index nitride, which reduces the impact toughness of the drill pipe, thus reducing the fatigue life of the drill pipe. Under the combined load, the transition section of the drill pipe has a high stress level, and there is a significant eddy current near the transition zone, and the total pressure of the drill pipe caused by the internal flow field is large. The drill string does not produce more severe whirl, and the amplitude of axial vibration and transverse vibration is small, but the vibration frequency of bending stress is twice of the rotation frequency of the drill string. The large dogleg of the failed drill string increases the bending stress, which makes the drill string more prone to fatigue failure.

The scaling problem of silicon in the heavy oil production of Shengli Oilfield will seriously affect the normal production and production. According to SYT 5523-2006 oilfield water analysis method, the ions in the water samples collected by each water treatment unit were analyzed, and it was found that the content of metasilicic acid in the high-temperature separation water was relatively high, so the effect of four kinds of desilication agents was studied in this paper. It is found that the effect of desilication agent is the best. Magnesium agent is selected as desilication agent. Through the orthogonal experiment of three factors designed by SPSS software, the factors influencing desilication effect are investigated. Through the analysis of SPSS, it is found that the effect of temperature on the experimental results is not significant. After comprehensive investigation, it is concluded that the effect of desilication is the best when the dosage of agent is 400mg/L, and the effect of desilication is the best when the pH is 10. According to the experimental data, it can be seen that the effect of desilication is the best when the dosage is 400mg/L The removal rate of silicon can reach more than 90%.

Microorganisms as the biotic factor are capable to participate in processes leaching of a rock of an oil layer directly, and also by secretion of various agents leaching -gases, acids, spirits, slime, etc. The basic mechanism leaching of a rock is formation of chelates by microbial agents with minerals of a rock. The order of carrying out of elements from minerals of rock of a class alumosilicates basically is defined by structure and property of the mineral. The elements making cristallic a lattice of a mineral will least intensively be mobilized; isomorphically replaced or exchange ions which are taking place on peripheral sites of mineral particles will most intensively be mobilized . Knowledge of physical and chemical features of a collector - the nature and a cementing mineral of a rock, his maintenance in a rock, type of cement (bazalic or pore type etc.) and other parameters, in the certain degree allow to predict probability of shaking of structure of a rock of a collector and speed of his destruction during technological influence. At selective leaching minerals of collector properties of rock can be modified both aside deterioration, and aside improvements of filtrational properties of pore spaces of a reservoir. Deterioration of collector properties can be shown, for example, in display sand recovery to wells-bottom (most likely in the first in sandy collectors with the small maintenance of a cementing material of montmorillonite type). In collectors with the high maintenance of a cementing material (bazalic or pore type of cement) leaching can promote substantial improvement of collector properties in connection with increase of permeability due to formation of secondary porosity.

Staged premium screen technology has been widely used in Shengli Oilfield, and works as a reliable method for sectional inflow control completion in horizontal wells. The completion plan of staged premium screen were originally optimized by flow loop test, however, the test procedure is usually as long as 12 working days. Therefore, a fast calculation method with processing time of no more than 2 days is proposed. When the well bore segmentation scheme is available, screen number as well as base pipe hole density are selected as the key parameters, and are optimized from one interval to the next on the basis of inflow control characteristics formula of staged premium screen. During the optimization of each interval, the parameters which best fit the requirements of “reasonable inflow control pressure drop” and “maximum discharge area” are determined from many alternative values. G6-P15 well, designed under the guidance of fast calculation method, obtained more balanced fluid and oil production profile versus Reference Well G6-P12. So far, 15 wells have been designed by this fast method. On average, the annual decline rate of daily oil production, the annual increase rate of water cut as well as annual mean of water cut of application wells are observed to be 36.7%, 9.4% and 7.9% lower than those of reference wells, respectively, while the annual accumulation oil production of target wells is 12.2% higher than that of reference wells. These successful applications prove that the fast calculation method has provided reasonable design.

A new artificial lift pump technology has emerged to increase the production of heavy oil in order to meet up high global demand for energy. The technology is a hybrid of two principal artificial lift pumps for lifting crudes. The hybrid called electric submersible progressive cavity pumps integrates the applicability and usefulness of electric submersible pump and progressive cavity pump. This gives it enhanced performance and more adaptability to varied reservoir conditions. This technology has the advantages of sample technology and management convenience. Electric submersible progressive cavity pump (ESPCP) is suitable for the viscous crude containing sand and high gas oil ratio oil extraction. In this paper, developing history of ESPCP is introduced and the structure and principle are analyzed. The advantages of ESPCP are compared with other oil extraction technology. In addition, the technical applicability of this new technology in the Niger Delta heavy oil fields and economic evaluation of the ESPCP were evaluated. The result of this research work showed that ESPCP showed better performance when compared with ESP and PCP making it a choice pumping system to replace the traditional gas lift predominant in the Niger Delta artificial lift operations.
