中文摘要：
煤层含气量是煤层气储层评价的重要参数,基于煤层含气量与测井参数的关系较为复杂,论文对煤层含气量与测井参数做相关分析,对于相关系数较小的参数,通过构造复合参数法,提高了含气量与参数的相关系数,最终共优选6种测井参数,建立含气量与测井信息的线性、二次多项式回归方程,并对预测值进行有效性检验,证明建立的线性和二次回归方程是有效的。
英文摘要：
Coal- bed methane content is an important parameter for evaluating coal - bed methane reservoir. And according to the complex relation between coal - bed methane content and logging parameters, relative research was conducted, and for parameters with small correlation coefficient, composite parameter was built to improve the correlation coefficient between content and logging. Linear and second - degree polynomials equations were established, for the content and logging, selecting 6 logging parameters, and availabihty of the equations was verified through validity check on the predictive value.
