摘要
确定煤层煤质和含气量是煤层气储层测井评价的重要内容。根据沁水盆地和顺地区的煤心实验数据,提取敏感的测井响应,用回归分析方法,分别得到利用自然伽马测井值计算煤工业组分的计算方法和利用声波时差和密度组合参数来计算含气量的计算方法,并指出了该方法在和顺地区的有效性及局限性。
Determining the quality of a coalbed and its gas content is an important task of coalbed methane reservoir evaluation.Using the core observations in coalbed from Heshun,Qinshui Basin and selecting sensitive logging parameters,this paper gets a calculation model of coal industrial component from gamma log and a calculation model of gas content from the combination of AC log and density log via regression analysis.The effectiveness and limitation of the proposed method were discussed.
