摘要
裂缝性储层预测是油气勘探中的难点,通常使用多种方法综合研究。针对裂缝性储层开展了基于纵波地震资料的裂缝性储层多种检测方法研究,分析了基于NMO速度的方位变化裂缝检测方法、正交地震测线纵波时差的裂缝检测方法、纵波AVO的方位变化检测裂缝发育、边缘检测技术识别裂缝发育带、相干数据体技术识别裂缝发育带和地震属性裂缝检测方法。从数值计算上或应用上对应用纵波地震数据检测裂缝性储层进行了探讨。
Fractured reservoir prediction was the critical point of hydrocarbon exploration,multiple methods were usually used for research.In consideration of the situation of fractured reservoirs,study on multiple mathads was carried out for predicting fractured reservoirs based on p-wave seismic data.The detecting methods were introduced for NMO velocity azimuth changes,orthogonality seismic survey line with p-wave time-difference,the azimuth changes for p-wave AVO detecting fractures,edge detecting technique for prediction of fracture development band,technique for predicting fracture development band and fracture detecting method of seismic attribute with coherent data.From numerical calculation or application the applications of p-wave seismic data detecting fracture reservoirs is discussed.
