摘要
煤层气是赋存于煤层中的自生自储式非常规天然气,它在气质组分、赋存条件、生产规律等方面均不同于常规天然气,具有典型的低渗、低压、低产的特点。以延川南区块延1开发试验井组地面集输系统为例,结合煤层气集输工艺调研,开展煤层气井场工艺、管输工艺、分离工艺、增压工艺等地面集输工艺技术研究,为延川南区块整体开发起到借鉴作用。
CBM is self-generating and self-preserving unconventional natural gas in coal beds. Characterized with low permeabili- ty, low pressure and low production, CBM differs from conventional natural gas in the aspects of gas quality component, preserva- tion conditions and production rules. By taking the example of surface gathering ＆ transportation system of Yan-1 well group of Yanchuannan block and combining with surveys of CBM gathering ＆ transportation technology, this paper conducted researches on the surface gathering ＆ transportation technology of CBM, including field technology, pipe transportation technology, seperation technology and pressurization technology. The results provided references for the overall development of Yanchuannan block.
