【摘要】 对采取的吉林省农安油页岩矿石进行了物理力学性能实验研究,获得了油页岩在平行于层理和垂直于层理两个方向上的抗压强度、抗拉强度、弹性模量和泊松比等力学数据。计算得到了毕奥特系数、平均压力和最小主应力等参数。确定了水力压裂中的裂隙开启、延伸压力及宽度等参数。更多还原

【Abstract】 Through the experiment of physical and mechanical properties,the mechanical data of compressive strength,the tensile strength,the elasticity modulus,Poisson’s ratio of oil shale in Nong’an mining site were obtained in both horizontal and vertical bedding direction.The Biot coefficient,the average pressure and minimum principal stress and other parameters were calculated.The parameters of crack opening,extending pressure and the width in hydraulic fracture were determined.更多还原
