摘要
根据辽河油田东部凹陷煤储层的地质特征以及实际煤岩芯分析资料和测井资料 ,利用回归分析方法得出了计算煤层各组分含量和煤阶的方法 ;通过分析煤层气特征 ,利用兰氏方程、吸附等温线和煤层气层中子背景值导出了煤层含气量的计算公式 ,并通过辽河油田东部凹陷实际煤储层测井资料的处理解释验证了方法的有效性。
In the light of geological characteristics and statistical as well as logging data of the coalbed in the eastern depression of Liaohe Oilfield, the authors used regression to make industrial analysis of coalbeds and coal ranks. Through the analysis of coalbed gas characteristics and the utilization of Langmuir's equation, sorption isotherm and neutron background value of coalbed gas, the formulae for calculating coalbed methane content were deduced. The techniques were proved to be effective by the practical well log data from the eastern depression in Liaohe Oilfield.
