基于地震数据的岩石弹性参数反演方法
Formation elasticity parameters inversion based on seismic data
摘要
Abstract
Aimed at the question that shear velocity information is frequently absent in Lame parameters inversion, a new Lame parameters inversion method without shear velocity was developed. Firstly, shear velocity near the well position was obtained through Bayesian inversion to pre-stack seismic data. Then Lame parameters dataset could be gotten by Lame parameters direct inversion. Combined with geology and well-log information, reservoir could be predicted and pore fluid could be i-dentified. The method was used to predict gas reservoir for J block, and the results agree well with the fact of drilling. The method expands the scope of application of Lame parameters inversion, and shows good practicability in reservoir prediction.关键词
