摘要
裂缝系统的形成常常受到构造运动及其作用强度的影响。裂缝的产生同构造应力场分布密切相关,构造应力场的作用效果又依赖于地层的岩石物性特征。本文从裂逢形成的外因———裂缝形成的古构造应力场出发,根据弹性力学理论,利用连续介质有限元数值模拟法和岩石破裂准则,研究某古潜山储层裂缝的方位、密度分布。运用该技术较为成功地预测了研究区内裂逢发育带的宏观平面分布
The generation of fracture system was usually influenced by tectonic movement and intensity, and closely related to tectonic stress field distribution. The impact of tectonic stress field relied on petrophysical property. This paper studies the fracture azimuth and density distribution of a buried hill reservoir by starting with the external cause of fracture generation-palaeotectonic stress field, according to elastic force theory, and using finite element numerical simulation of continuous medium and rock-breaking standard. The areal distribution of fracture zones in the study area is successfully predicted by this method.
