【摘要】 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。利用地震资料确立了该区地层层速度与地层压力之间的函数关系,并运用异常孔隙流体压力、地层曲率和相千体等技术对该区裂缝性储层的平面分布规律进行研究,预测了该区主要的裂缝发育区带。更多还原

【Abstract】 Fracture genesis mechanism in ZJD area is analyzed from the aspects of abnormal pore fluid pressure in formation, local structural deformation, and fracturing etc. Functional relationships between formation velocity and formation pressure in the area are established by using the seismic data. Areal distributional laws of the fractured reservoirs are studied , the fracture growing zones are predicted in the area by using the abnormal pore fluid pressure, formation curvatures and coherent volume technique.更多还原
