Abstract

The electrodynamics of geological media investigates the interrelations of resistivity logging signals and properties of fluid-containing rocks and creates innovative well logging technologies. Its development is inextricably linked with modern techniques for mathematical modeling and quantitative interpretation of high-precision data. In order to increase the information content of galvanic and electromagnetic logging, we have developed algorithms and software for numerical simulation and inversion of field data. In our study of the Cretaceous and Jurassic deposits of West Siberia, a quantitative interpretation of high-frequency electromagnetic and lateral logging signals was carried out. To create geoelectric models, we interpreted the field resistivity logging data by an unconventional quantitative technique based on their joint numerical inversion and estimations of the vertical resistivity of permeable deposits. Another line of our research was aimed at a scientific substantiation of a new technology for mapping and spatial tracking of lateral heterogeneities and oil-promising zones in the Bazhenov Formation. The aim was achieved by using the TEM sounding data on a spatially distributed system of directional and horizontal wells.

电阻率测井资料解释的现代算法和软件

地质介质的电动力学研究了电阻率测井信号与含流体岩石性质的相互关系，并创造了创新的测井技术。它的发展与现代数学建模和高精度数据定量解释技术密不可分。为了增加电、电磁测井的信息量，我们开发了现场数据的数值模拟和反演算法和软件。在西西伯利亚白垩系和侏罗系沉积研究中，对高频电磁信号和横向测井信号进行了定量解释。为了建立地电模型，我们采用了一种非常规的定量技术，基于它们的联合数值反演和渗透性矿床的垂直电阻率估计，解释了场电阻率测井数据。我们的另一项研究旨在为Bazhenov组横向非均质性和油区的测绘和空间跟踪新技术提供科学依据。利用空间分布的定向井和水平井系统的瞬变电磁法测深数据实现了这一目的。
