叠前弹性参数反演在浅层气藏识别中的应用
APPLICATION OF PRESTACK ELASTIC PARAMETER INVERSION IN THE IDENTIFICATION OF SHALLOW GAS RESERVOIR
摘要
Abstract
The process of prestack time migration for shallow layer provides high-quality CRP gather data. Through the standardized process of sample tests and well logs, the shear wave prediction and petrophysical analyses of well logging are caught out, the petrophysical chart board to identify gas layer has been established, and finally the elastic parameters which are sensitive to the gas layer have been optimized. With the help of the above parameters, the data volume of the elastic parameters is inverted. The coincidence ratio of the obtained prediction results for gas layer is more than 80% by means of the cross and analyses of the elastic parameters taking petrophysical chart board as standard. The results of the correlation and inversion show that the vertical resolution of elastic parameter inversion is beneficial to the identification of thin interbeded gas reservoir.关键词
