摘要
根据弹性力学和最大拉应变强度理论及等围压实验,对岩盐水力压裂钻孔周围的应力应变场进行了研究,建立了水力压裂的理论破裂准则,并通过实验进行了验证。
The criterion for the hydraulic fracturing theory is developed on the basis of elasticity, maximum tensile stress strength theory and equal ambient pressure test as well as studies on stress and strain fields around hydraulic fracturing boreholes for halite. It proves successful in all tests.
