| 摘 要： | 提出了以地震属性和钻孔测井参数为基础，以数学地质为桥梁，实现煤层气储层参数定量预测的科学方法。薄煤层厚与反射波振幅之间为单调增减关系公式；孔隙度与地震反射瞬时频率成正比关系，可采含气量与地震反射瞬时振幅成反比关系，且相关程度高。最后应用该成果对山西沁水煤层气地震勘探工程实际预测，对储层厚度、孔隙度、含气量做出定量预测。该成果有利于提高煤矿采煤安全性和降低煤层气开采的风险性，同时也将开拓地震勘探技术新的应用领域。 |

| Abstract: | A new methodology is presented to predict coalbed gas reservoir parameters at relationship of seismic attribute and geological information.The basic methodology is to build a mathematic model through the regression analysis of the mathematic geology.Two achievements have been acquired. The first is that the equation of thin bed coal seam thickness to the reflecting amplitude; the second is that setting up the regression equation: one is the porosity-to-instantaneous frequency; the other is the gas-product percentage to the reflection amplitude. At the end, application of the research results to the Shanxi Qinshui coalbed gas seismic exploration project shows a satisfaction results and produce great economic interests.The study results are useful for inereasing the mining safety and decreasing the mining risk,as well as developing a new application field. |
