裂缝性储层的预测方法及应用

描述裂缝储层的主要参数有裂缝的形状、方位和密度等，这也是控制产油产气的主要因素。简要介绍了YC地区泥岩裂缝储层的地质特征与测井显示，综合分析不同观测方位的三分量地震转换波资料，九分量VSP资料，以及三维特殊地震属性等资料，对裂缝段进行了横向预测和描述的方法探索。结合AVO资料及所提取的地震属性，预测了YC地区储层段的裂缝密度和主方位角。

Prediction of fractured reservoirs using seismic technology and its application

The geometry and density of fractures are the main parameters used to describe fractured reservoirs, and they are also the main factors controlling the oil & gas production of fractured reservoirs. In this paper, evidences of fractures from cores and borehole image logs are integrated with those from 3-component seismic converted wave data in different directions, 9-component VSP, and 3-D seismic reflection data, to develop an understanding of how seismic data depicts fractures. AVO, inversion data, and other attributes of seismic reflection data sets is used to detect and characterize fracture density and dominant fracture azimuth in YC area.
