摘　　要：以沁水盆地东南部煤层气垂直井勘探开发资料为基础,采用数值分析方法,分别得出了不同构造部位煤层气资源条件(含气量、资源丰度、煤层厚度)及资源开发条件(储层压力、渗透率、含气饱和度)与平均日产气量的关系。对比结果表明:在小范围内且不考虑开发工艺条件时,资源丰度、含气饱和度对煤层气垂直井产能的贡献最大,因此寻找高资源丰度、高含气饱和度是煤层气垂直井勘探开发成功的重要保证。Based on the exploration development information of the coal bed methane vertical well in the south part of Qinshui Basin,the numerical analysis method was applied to obtain the relationship between the coal bed methane resources conditions（gas content,resource richness and seam thickness） in different tectonic locations as well as the resources development conditions（reservoir pressure,permeation rate and gas content saturation） and the average daily methane production.The comparison results showed that when in a small scale of the coal bed methane development not consider of the development technique conditions,the sources richness and gas content saturation could make the maximum contributions to the production capacity of the coal bed methane vertical drilling well.Thus to seek the coal bed methane with high resources richness and high gas content saturation would be the important guarantee to the success of the coal bed methane vertical well exploration and development.
