On the basis of the predicted results and rock mechanical model, the vertical effective pressure is obtained. Pore pressure of formation can be calculated by using the effective pressure principle.
利用预测结果结合岩石力学模型得到垂直有效应力，最后根据有效应力原理计算地层孔隙压力。
The pore pressure also strongly influences the state of stress in a formation (by as much as 50%) and is therefore a critical piece of information for designing hydraulic fracturing treatments.
孔隙压力也强烈地影响地层中的(多达50%)的应力状态，并针对设计水力压裂处理而言是一项重要信息。
Fracture genesis mechanism in ZJD area is analyzed from the aspects of abnormal pore fluid pressure in formation, local structural deformation, and fracturing etc.
从地层的异常孔隙流体压力、局部构造形变、断裂作用等多方面分析了ZJD地区裂缝的成因机理。
