【摘要】 本文提出，在测井孔隙度、岩心孔隙度的监控下，借助测井—井旁地震道约束反演的速度，结合井旁地震道的瞬时振幅、瞬时频率，建立泥质含量、有效孔隙度计算方程，用TFI模糊聚类算法识别油气层，为今后作好储层横向预测，对井旁地震道进行储层评价作准备。本方法在四川地区的3口井的应用效果较好。更多还原

【Abstract】 Under the control of log porosity and core porosity, with the aid of velocity obtained from well log-ging and constrained inversion for near-well seismic traces, we build the computation equation of shale content and effective porosity by combining with the instantanans amplitude and instantaneous frequen-cy of near-well seismic traces. The TFI fuzzy clustering algorithm is used to identify gas, which provides the basis for reservoir lateral prediction and evaluation for near-well seismic traces. The application resultof the method in Sichuan area is good.更多还原
