利用测井资料计算煤层含气量及工业组分方法研究

The method of calculating gas content and industrial components of coalbed by using well logging data

煤层气作为非常规能源,越来越得到重视。煤层气的测井识别和相关参数的计算是个重要而困难的问题,尤其是预测含气量及工业组分,难度较大。在调研相关文献的基础上,结合生产中的实例,利用测井数据、岩心分析数据及生产数据等资料,应用相关数学方法及经验,并采用复合参数来建立煤层含气量及工业组分的测井预测模型,应用效果较好。

Coal bed methane has been gaining more and more attention as a kind of non-conventional energy resource.Logging identification and the calculation of related parameters of coal bed methane is an important but difficult problem,especially the prediction of gas content and industrial components.Based on the research of related document and practical cases,and combined with logging data,core data,production data and other information,this paper proposed the logging evaluation method to predict gas content and industrial components of coal bed by using mathematical method and composite parameters.This method had achieved great success in practical application.
