基于EI-Fatti弹性波阻抗反演的流体识别
FLUID IDENTIFICATION BASED ON EI-FATTI ELASTIC IMPEDANCE INVERSION
摘要
Abstract
EI-Fatti elastic impedance inversion can directly yield P-wave impedance, S-wave impedance and density data. The tentative calculation of reflection coefficients of three AVO models shows that the inversion method meets the requirements of inversion precision. Meanwhile, based on EI-Fatti elastic impedance of two fluid factors, the three AVO models were comparatively studied, and the results show that the two fluid factors show different fluid identification effects for different AVO models. Meanwhile, through the intersection and correlation analysis of elastic parameters and reservoir parameters, qualitative and quantitative fluid identification can be carried out, so the gas reservoir can be distinguished from the fizz reservoir in actual data.关键词
