沁水盆地煤层气地面工艺技术

CBM GROUND TECHNOLOGY IN QINSHUI BASIN

沁水盆地煤层气资源丰富,其开发和利用具有重要意义。针对沁水盆地煤层气田低渗、低压、低产等特点,介绍了适用于沁水盆地煤层气田地面建设的"低压集气、单井简易计量、多井单管串接、二次增压、集中处理"等一系列集输新工艺技术,以便为今后煤层气的工业化开发和建设提供有益的借鉴。

The Qinshui Basin is rich in coalbed methane whose development and usage are of importance.In view of the characteristics of coalbed methane in the Qinshui Basin such as low permeability,low pressure and low production,this article introduces briefly a set of new gathering technology that is suitable for the ground construction of coal bed methane in the Qinshui Basin,for example,gas collection with low pressure,simple calculation of single well,multiwell pipe string connection,secondary boosting and central treatment,which can provide beneficial reference for industrial construction and development of coalbed methane.
