【摘要】 从理论上分析了倾斜仪裂缝动态监测技术的基本原理,应用FLAC3D模拟分析软件建立了水力压裂过程地层及垂直裂缝模型。通过模拟研究,分析了地下裂缝对其上部地层岩石的影响作用过程,得到了水力压裂施工过程中施工井地表倾斜变形的规律。对水压裂缝监测的倾斜仪监测技术的数据解释有积极意义。更多还原

【Abstract】 This paper analyzes the basic principle of fracture performance monitored by tiltmeter,creates a model of the reservoir with a vertical fracture and the process of fracturing with the 3D simulation software FLAC,analyzes the influence process of fracturing to the upper formation and obtains the law of inclination and deformation of the earth surface occurring in fracturing process.The result is helpful for the interpretation of data about the fracture monitored and recorded by the tiltmeter during hydraulic fracturing.更多还原
