叠前地震保真高分辨率处理技术在西南某地页岩气微幅裂缝中的应用实践
Application of prestack seismic fidelity and high-resolution processing technology in micro-fractures of shale gas in southwest China
摘要
Abstract
Weiyuan shale gas has complex geological conditions,strong heterogeneity,thin reservoirs,and unstable lateral distribution.The results obtained by conventional seismic processing methods have low resolution and cannot identify thin lay-ers,formation pinch-out points,and micro-fractures.In order to solve these problems,this paper uses high-fidelity,high-resolution seismic processing technology to process the seismic data of Weiyuan shale gas.The orderly combination of meth-ods such as correction,pre-stack residual multiple suppression,and high-precision well seismic calibration quantitative qual-ity control can effectively improve the resolution,signal-to-noise ratio,and fidelity of complex seismic data.The processing results prove that this method can improve seismic data's resolution and well-seismic correlation coefficient in this area.At the same time,the interpretability of thin layers,the continuity of events,the accuracy of pinch-out points,and the reliability of fault detection are enhanced.关键词
