Abstract

Block-granular geological objects and rock volumetric mobility indicators are described. The mechanisms of structural and material reworking of rocks are considered in relation to the formation of a discrete tectonic structure of rocks and changes in the shapes of the geological bodies, which take place without rupturing the rock surfaces bounding these bodies and provide for the volumetric tectonic flow of solid rocks. Based on the study of natural objects and their comparison with the theoretical and experimental data on solid mechanics and geomechanics, it is suggested that one of the triggers for the volumetric disintegration of rock masses is rock fatigue damage (a fundamental phenomenon of solid-state physics). The disintegrated rocks behave according to the laws of mechanics of granular materials and mesomechanics. This study is of both theoretical and pragmatic importance as it contributes to the understanding of the regional geological features and provides new knowledge on the formation of crystalline protrusions known among the main hydrocarbon reservoirs within the basements of various geologic structures.

岩石松动的构造:地质资料和过程的物理
描述了块粒状地质对象和岩石体积流动性指标。岩石的结构和物质改造的机制被认为与岩石的离散构造结构的形成和地质体形状的变化有关,这些变化发生在没有破裂这些体的岩石表面的情况下,并提供固体岩石的体积构造流。通过对自然物体的研究,并与固体力学和地质力学的理论和实验数据进行比较,认为岩石疲劳损伤(固体物理的基本现象)是岩体体积解体的触发因素之一。岩石的破碎行为符合颗粒材料力学和细观力学的规律。该研究有助于认识区域地质特征,并对不同地质构造基底内主要油气藏的结晶突出形成提供新的认识,具有重要的理论意义和实用价值。
