| 摘 要： | 海相碳酸盐岩地层原生孔隙较少而裂缝较发育,利用测井资料计算其破裂压力难度较大.依据弹性力学原理和岩层破裂机制,综合考虑三向地应力及地层特征对地层破裂压力的影响,建立一种新的适合海相碳酸盐岩地层的破裂压力计算模型.川东北通南巴构造上5口井的应用结果表明,利用该模型计算得到的破裂压力值与实测值误差较小,能够满足工程计算要求.

| Abstract: | The primary pore didn't develop and fracture developed in marine carbonate formation, so it is difficult to compute the fracture pressure by using log data. According to the elastic mechanics rule and rock stratum break mechanism, considering tri-crustal-stress and formation characteristic, a new prediction model of fracture pressure of marine carbonate formation was established. The application results of five wells in Tongnanba structure of northeast Sichuan indicate that the fracture pressure error obtained by this model is small enough to achieve the engineering calculation demand. |
