我国具有丰富的煤层气资源,近几年我国政府非常重视煤层气产业发展,目前煤层气的采出技术及地面工程集输工艺逐步成熟。煤层气井口气体产量较低且不稳定,压力较低且波动较大的特点;经过大量调研对比,低压煤层气采气管道管径小于DN200的采用聚乙烯(PE)管道具有减少投资,施工方便,耐防腐等特点;针对这些特点分析探讨煤层气聚乙烯采气管道设计技术。
China has abundant CBM resources. In recent years, the Chinese government attaches great importance to the development of the CBM industry. At present, the CBM recovery technology and the ground transportation project have gradually become mature. After a lot of research and comparison, the use of polyethylene (PE) pipe with a diameter of less than DN200 for the CBM gas production pipeline has the advantages of less investment and more convenient construction , Anti-corrosion and other characteristics; in view of these characteristics analysis of coalbed methane polyethylene gas pipeline design.
