煤层气有利储层分布区测井、地震联合预测方法
Logging-seismic combination forcasing method for beneficial coalbed methane distribution
摘要
Abstract
Logging data,seismic data are comprehensive used in forecasting beneficial coalbed methane distribution.In study,with validated application of logging data,according to the vertical distribution of logging response characteristics and its classification of the main target 3rd coal layer and the upper small coal bed,combined with the property difference between coal and surrounding rock caused by the variation characteristics of lateral seismic amplitude to predict the transverse distribution of coal seams.Validated geophysics parameter is chosen through logging data analysis and seismic RMS amplitude parameter is chosen to depict seismic fancies in SMB area,the fancies boundary is obvious.With test site's geology background's comprehen-sive analyzed and logging and seismic data are used to describe the test site's seismic fancies and sedimentary fancies.Delta in-terdistributary bay deposit area is chosen as optimized coalbed methane distributed area and beneficial coal bed distribution is predicted.关键词
