Abstract

—This paper presents a solution to the problem of searching for cavernous fractured zones and the zones that determine reservoir heterogeneity in Famennian deposits of one of the licensed sections of the Republic of Bashkortostan. The use of an integrated approach to the study of azimuthal horizontal-transverse isotropy of rocks using wellbore data and modern methods for processing areal seismic data for carbonate deposits associated with the development of organogenic structures is described. The results of using the full-azimuth angular migration technology are obtained. The introduction of high-tech approaches at the research site using full-azimuth seismic data processing, spectral decomposition, AVA/AVAZ inversion, and complex analysis of dynamic properties of the wave field in conjunction with well logging and core data makes it possible to identify the distorted zones of the carbonate reservoir associated with changes in the characteristics of the rock skeleton, the presence of a porous-cavernous-fracture void space and lithological replacement zones, as well as secondary processes, thereby reducing the risks associated with subsequent production drilling.

-本文介绍了在巴什科尔托斯坦共和国一个特许地段的法门岩矿床中寻找洞穴断裂带和决定储层异质性带的解决方案。介绍了利用井筒数据和现代方法处理与有机成因结构发育有关的碳酸盐岩矿床全方位地震数据的综合方法来研究岩石的方位角水平-横向各向同性。获得了使用全方位角迁移技术的结果。在研究地点采用全方位角地震数据处理、频谱分解、AVA/AVAZ 反演和波场动态特性复杂分析等高科技方法，并结合测井和岩心数据，可以确定碳酸盐岩储层中与岩石骨架特征变化、多孔-空洞-断裂空隙和岩性置换区的存在以及次生过程有关的变形区，从而降低与后续生产钻井有关的风险。

期刊介绍： The journal publishes original reports of theoretical and methodological nature in the fields of geology, geophysics, and geochemistry, which contain data on composition and structure of the Earth''s crust and mantle, describes processes of formation and general regularities of commercial mineral occurrences, investigations on development and application of geological-geophysical methods for their revealing. As to works of regional nature, accelerated publication are available for original papers on a variety of problems of comparative geology taking into account specific character of Siberia, adjacent Asian countries and water areas. The journal will also publish reviews, critical articles, chronicle of the most important scientific events, and advertisements.
