摘要
研究煤层气的可压性,优选出与煤层气可压性相关的参数,用物元可拓模型和主客观组合权重法,对可压性评价准则进行统计分析参数,物元构造和确定待评物元,应用到煤层气可压性评价实例中,结论也验证了采用方法的可靠性。
The compressibility of coal-bed methane is studied,and the parameters related to the compressibility of coal-bed methane are optimized.By using matter-element extension model and subjective and objective combination weight method,the compressibility evaluation criteria are statistically analyzed,and the matter-element structure and the matter-element to be evaluated are determined,which are applied to an example of coal-bed methane compressibility evaluation.The conclusion also verifies the reliability of method.
