沁南地区潘庄区块煤层气井产能主控因素研究

摘要

研究煤层气井产能的主控因素对煤层气高效开发具有重要意义.以潘庄区块煤层气勘探开发资料为基础,从资源条件、水文地质条件、钻完井工艺和排采工作制度4个方面对煤层气井产能的影响进行分析,得出了在资源丰度差别不大的情况下,煤储层含气饱和度和临储压力比对该区煤层气井产能贡献大,其中临储压力比贡献最大,煤储层含气饱和度次之,而水文地质条件以及排采工作制度对煤层气井产能影响不明显.%Coalbed methane(CBM) production and efficient controlling factors that is favorable to CBM development is of great significance. Based on Panzhuang block exploration and development information, the resource conditions, hydrogeological conditions, drainage and gas drilling and completion technology, and work systems to CBM well productivity in terms of the impact analysis, it is concluded that when the abundance of resource circumstances is not very different, the coal reservoir gas saturation and pressure contribute to a large CBMwell productivity, and that contribute to pressure is the largest reservoirs of coal gas saturation followed. The strength of hydrogeological conditions and mining system of work scheduling on CBM production was not obvious.
