Law of Fracture Expansion of Deep Sandstone in Jingbian Area

摘要

摘要: 为了更好地对深井围岩中的微小裂隙进行注浆封堵,利用ABAQUS数值模拟软件,基于水力压裂理论,以靖边地区深为1 500 m左右的砂岩为例,通过建立水力压裂数值模型,对裂隙的扩展情况进行模拟。结论表明:在地应力、水力压力、弹性模量的影响下,裂隙的扩展具有明显规律性,而天然裂缝对裂隙扩展的影响较小。

Abstract: To better seal and plug micro fractures in the surrounding rock of deep wells, the numerical simulation software ABAQUS is used to simulate the expansion of fractures by establishing a hydraulic fracturing numerical model for the sandstone about 1 500 m in Jingbian Area based on the hydraulic fracturing theory. The conclusion shows that, under the influence of in-situ stress, hydraulic pressure and elastic modulus, fracture propagation has obvious law, while natural fracture has little effect on fracture propagation.
