基于常规测井资料的煤层岩石参数解释方法，在分析煤层及其特征的基础上，优选了计算煤层岩石参数的模型，提出了根据室内岩心测试结果转换动、静态弹性参数的手段，建立了利用压裂施工资料反演煤层构造应力系数等的最优化模型和算法，从而形成了经济实用的煤层岩石参数解释方法。鄂尔多斯盆地韩城区块的应用情况表明，该方法可准确可靠地解释泊松比、弹性模量、抗张强度、三向应力、破裂压力等煤层岩石参数，能满足煤层气资源评价、钻井、增产、排采等各环节的需要。

The models of calculating rock parameters of coal-seam were optimized on the basis of common log information.It was put forward that transforming dynamic and static elastic parameters by indoor core test results.The optimized model and algorithm for re-gressing tectonic stress coefficient by fracture construction information were set up which was economical and practical rock parameter explanation method.Actual application in Hancheng block of Erdos Basin showed that this method could precisely and reliably explain Passion ratio, elastic module, tension strength, 3-d stress, fracture pressure and other rock parameters , and meet the demand of coal-bed methane resource evaluation , boring, production increase and drainage.
