【摘要】 地震数据保幅性处理是一项复杂的系统工程。笔者分析了实际地震数据处理流程中各个关节点模块的保幅性,重点评价了反褶积和振幅补偿的保幅性,并论述了俞氏子波统计反褶积比预测反褶积有更好的保幅性,而剩余振幅补偿需要用叠前弹性阻抗或者叠后反演结果来检验其保幅性。根据上述的保幅性分析结论,对目标区进行了保幅性的地震数据处理,运用叠前弹性参数反演的方法预测了该区的含油气性,其预测的结果与钻井结果相符合,说明了该文采用的保幅处理流程和方法能够提供一套保幅性比较可靠的基础数据。更多还原

【Abstract】 Relative amplitude of seismic data processing research is a complicated system engineering.The authors analyzed the key to evaluating the deconvolution and relative amplitude compensation in practical seismic data processing flow,and pointed out that Yu wavelet statistical deconvolution has better predictive deconvolution in relative amplitude,and that residual amplitude compensation needs to use prestack elastic impedance or post-stack inversion results to verify relative amplitude of residual amplitude compensation.According to the principle of relative amplitude,the relative amplitude of seismic data are processed in the target area,and then prestack elastic parameters inversion is used to forecast the oil-gas possibility. The prediction result is consistent with the drilling result,thus demonstrating that the relative amplitude flow and methods have good application prospect.更多还原
