纵、横波速度和密度重构算法在苏里格地区的应用
Application of the reconstruction algorithms of the elastic impedance and density in Sulige Gasfield
摘要
Abstract
Taking Sulige gasfield as an example, the reconstruction algorithms of p-wave and s-wave velocity and density that don t rely on the division of velocity are put forward based on the analysis of the widely used reconstruction algorithms at present. The possible fluid distribution or lithology distribution is predicted by using the crossplotting of elastic impedance data of different angles. The li-thology and liquid variation will lead to the variation of p-wave and s-wave velocity and density, so the fluid distribution or lithology distribution can be studied by the variation of p-wave and s-wave velocity and density. The results of a case show that various parameters can be accurately reconstructed using improved algorithms only under the condition of maximum angle over 30?,and multi-angle elastic impedance inversion provides the possibility of merely using p-wave's' information to reconstruct the p-wave and s-wave velocity and density.关键词
