这里综合应用测井和地震资料，进行有利煤层气储层分布区的预测。在研究中，有效应用测井资料，根据S MB工区3号主力煤层及其上部小煤层对应的测井响应特征纵向组合分布及其分类，结合煤层与围岩间的物性差异所引起的地震振幅横向变化特征对煤层的横向展布进行预测。通过测井和地震资料分析，选择地震均方根振幅属性进行S MB 工区煤层分布区地震相带的刻画，地震相带边界明显。综合分析试验区沉积地质背景，有效应用测井资料及地震资料，进行试验区地震相、沉积相的描述，优选了有利的煤层分布区即三角洲分流间湾沉积区，实现了煤层气有利储层分布区的预测。

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.
