摘要: P道集的地震波是按照射线路径传播的,与角度道集相比,更接近地震波的实际传播路径,更能表征地下的反射特征。同时P道集可直接从地震数据计算得到,不依赖于上覆地层速度,避免了不精确的速度模型给反演带来的误差。文章在介绍P道集基本概念及射线参数域叠前弹性参数反演流程的基础上,利用分P叠加数据,通过贝叶斯稀疏脉冲反演进行了不同P值的射线弹性阻抗反演,并通过约束搜索法求取了相关的叠前弹性参数。相比于角度域的叠前弹性参数反演,其反演结果具有高分辨率、高精度且客观真实的特点。将该方法应用于川西坳陷新马滚动区以及川北坳陷元坝西区的储层预测,实际应用效果证明了该方法的可靠性和准确性,其预测结果对研究区下一步的勘探开发工作具有重要的指导意义。

Abstract: The seismic wave of P gather is ray path.Compared with angle gather,it is more close to the actual path of seismic wave and can express the subsurface reflection characteristics better.Moreover,ray parameter can be obtained directly from seismic data and does not depend on the speed of overlying strata,which avoid the inversion error caused by inaccurate velocity model.After the introduction of basic concepts and elastic parameters inversion of ray parameters,ray elastic impedance inversion of different ray parameters have been done with the method of Bayesian sparse pulse inversion on the basis of P stack data.And elastic parameters have been obtained with constrained searching method.Compared with the pre-stack elastic parameter inversion based on angle,the inversion results of the new method have high resolution and high accuracy.The method has been used to predict the reservoirs of Xinma and Yuanba areas in Sichuan Basin.Exploration results confirmed that the method is reliable and accurate,and the inversion results have significant meanings for the late exploration.

Key words: P gather, Ray path, Angle gather, Ray elastic impedance, Pre-stack elastic parameter inversion
