In time domain, velocity difference section, the difference between the normal compaction velocity and the observed seismic interval velocity, can detect the area of overpressured formations qualitatively.
在四川盆地通南巴构造带,首先以井芯、录井资料和钻井泥浆比重资料为约束条件,利用泥岩段声波测井资料建立区域"正常压实趋势线";然后用精细速度处理获得的地震层速度剖面减去区域"正常压实趋势线"建立速度差值剖面,速度差值剖面上的异常低速带定性指示了地层超压范围;再采用速度 压力变换技术,建立压力系数剖面,定量分析地层超压,地层压力计算结果与实际钻井采用的泥浆比重较好吻合,说明利用地球物理资料、钻井资料及地质资料不但可以定性识别超压地层,而且可以定量预测地层压力;对不同压力封存箱的认识有助于分析地层含油气性延展方向,指导下一步勘探部署。
