摘　　要：东胜气田气井排水采气时存在单井产液量无法计量、泡排加注制度不明确、低压气井排液难度大、高产液井水淹后复产困难等问题,对上述存在问题及技术难点进行分析,分别提出井下节流器井流温流压测试、橇装计量单井产液量、应用抽油机排水采气工艺、完善气井气举施工工艺流程、"井下隔热+地面节流"工艺等措施,取得一些关于低压集输下排水采气工艺上的认识和成果,为东胜气田稳定高效开发奠定了基础,并为同类气田在低压集输工艺下的排水采气提供了借鉴。In the proc es s of the gas wel l product ion of Dongs heng gas field, is s ues hav e been existed in drainage gas recoverysuch as immeasurable liquid,undefined bubble row filling system, difficult drainage of low pressure gas wel l and difficult production recovery of high liquid wel l . Based on analysis of existing issues and technical difficulties in this article, measures as pressure and temperature test of downhole choke well, package metering of single-wel l , ^underground heat insulation and ground throttle^ , pumping drainage gas recovery test and improved construction technology of gas lift have been put forward. Certain understanding and achievements have been achieved about drainage gas recovery of downhole throttling well, which lays a sol id foundation for stable and efficient development of Dongsheng gas field, meanwhi le provides reference for drainage gas recovery of simi lar gas reservoir.
