摘　　要：单井增压技术是煤层气开发后期提高煤层气产量和采收率的重要技术措施。采用单井增压技术,可将煤层气井井口套压降至负压。煤层气田采用单井加压开采后,单井平均增产27.8%,单井采收率提高30%~40%,取得了良好的应用效果。文章通过对压采工艺原则以及可采储量的分析,对煤层气单井增压开采技术进行了研究,以期为提高煤层开发的经济效益提供理论基础。Single well pressurization technology is an important technical measure to improve CBM production and recovery in the later stage of CBM development.Using single well pressurization technology,the wellhead casing pressure of CBM well can be reduced to negative pressure.After using single well pressurized production,the average production increase of single well is 27.8%,and the recovery rate of single well is increased by 30%~40%.Through the analysis of the principle of pressure production technology and recoverable reserves,this paper studies the single well pressure production technology of coalbed methane in order to provide a theoretical basis for improving the economic benefits of coal seam development.
