摘　　要：煤层气含气量评价是煤层气勘探领域的热点问题,对指导煤层气开采意义重大。而煤层气含气量的多少是取决于煤层厚度。因此,使用沁水盆地某区块的测井资料和地震数据进行基于模型的波阻抗叠后反演,对基于模型反演方法的每个环节进行详细表达。得到最终反演结果,获取煤层气储层的厚度参数,对于煤层气的识别是一种有效手段。The evaluation of coalbed methane gas content is a hot issue in the field of coalbed methane exploration, which is of great significance for guiding coalbed methane exploitation. However,the gas content of coalbed methane depends on the thickness of coal seam. Therefore, this paper uses the logging data and seismic data of a certain block in Qinshui Basin to carry out the modelbased wave impedance post stack inversion, and expresses each link of the model-based inversion method in detail, and obtains the final inversion results. It is an effective method for the identification of coalbed methane to obtain the thickness parameters of coalbed methane reservoir.
