Abstract

The article describes the possibility of using the granulometric analysis of rock cuttings formed in controlled core scratching tests to estimate the angle of internal friction.The study object is the Kovykta gas-condensate field (GCF) that occupies a wide area in the southeastern part of the Irkutsk amphitheater of the Siberian platform. This uniquely complex geological structure holds significant reserves of hydrocarbons. Its sedimentary cover is composed of the Vendian – lower Paleozoic and partly Riphean formations. Their total thickness exceeds 6000 m, as estimated from the new seismic survey data [Vakhromeev et al., 2019].The sedimentary cover of the Kovykta GCF has been studied by surface and borehole geophysical techniques, remote sensing and geostructural methods, in combination with the tectonophysical approach [Seminsky et al., 2018] based on drilling data, including standard and special core sampling data.

科维克塔油田沉积盖层岩石划伤试验中组分含量估算内摩擦角分析

本文介绍了利用岩心可控刮擦试验中形成的岩屑粒度分析来估计内摩擦角的可能性。研究对象是Kovykta凝析气田(GCF)，该气田位于西伯利亚平台伊尔库茨克圆形竞技场东南部的大片区域。这种独特复杂的地质构造蕴藏着大量的碳氢化合物。其沉积盖层由文代—下古生代地层和部分里番地层组成。根据新的地震调查数据估计，它们的总厚度超过6000米[Vakhromeev等人，2019]。基于钻井数据，包括标准和特殊岩心采样数据，采用地面和钻孔地球物理技术、遥感和地质构造方法，结合构造物理方法[Seminsky等，2018]研究了Kovykta GCF的沉积覆盖。

期刊介绍： The purpose of the journal is facilitating awareness of the international scientific community of new data on geodynamics of continental lithosphere in a wide range of geolchronological data, as well as tectonophysics as an integral part of geodynamics, in which physico-mathematical and structural-geological concepts are applied to deal with topical problems of the evolution of structures and processes taking place simultaneously in the lithosphere. Complex geological and geophysical studies of the Earth tectonosphere have been significantly enhanced in the current decade across the world. As a result, a large number of publications are developed based on thorough analyses of paleo- and modern geodynamic processes with reference to results of properly substantiated physical experiments, field data and tectonophysical calculations. Comprehensive research of that type, followed by consolidation and generalization of research results and conclusions, conforms to the start-of-the-art of the Earth’s sciences.
