临兴先导试验区煤层气开发集输工艺技术研究

Gathering and Transportation Process Technology Research for Linxing Pilot Test Coalbed Methane Area

临兴区块煤层气资源丰富,为解决目前当地居民用气迫切需求,隶属该区块的先导试验区将率先开发。针对该区块气田井型多,压力衰减不一致的特点,介绍了适用于多压力体系集输系统的"站外高中压集气、站内分体系处理、先增压后脱水"等一系列集输工艺技术,为今后该区块煤层气的工业化开发和建设提供有益的借鉴。

Linxing block has rich coalbed methane resource.The pilot test area belonging to the block will take the lead in development in order to solve the current local residents gas demand.This paper introduces the suitable gathering and transportation process system for multiple pressure system based on characteristics of multiple block type and pressure decay.Such as high and middle pressure gas collection technology outside station,different treatment process for different pressure system,pressurization before dehydration.This paper will provide beneficial reference for the industrialization development and construction of the coalbed methane block.
