摘　　要：苏里格气田普遍采用井下节流的生产工艺,虽达到了简化气井地面流程、节约开采成本的目的,但同时也给气井动态监测和压力测试带来了困难。多年来,苏里格气田不断探索适合实际情况的气井压力监测分析方法,从不关井测压技术、井筒液面监测技术、井口压力折算技术入手,形成了一整套具有苏里格气田特色的压力动态监测方法,并试验成功了基于井口数据采集、集气站进行处理分析的远程试井技术和不稳定试井分析技术,实现了压力计不下入井下开展气井测试工作的目标。现场应用表明,该套技术基本满足了苏里格气田气井动态分析和生产管理的需求。The Downhole choke technology is widely used in the Sulige Gas Field with the purpose of simplifying the ground flowsheet and cutting down the cost.On the other hand,this also brings about difficulties in dynamic monitoring and well testing.That is why for so many years better methods of gas-well pressure monitoring and analysis have been kept exploring adaptable for actual cases.These characteristic methods include the pressure test without shut-in,liquid level monitoring in the wellbore,and wellhead pressure conversion.In addition,successful field tests for remote well testing and transient well test analysis based on data acquisition from wellhead and in gas gathering station help achieve the well testing directly from wellhead instead of down-placing the pressure gauge.Application in a real case shows that this set of techniques meet the requirements for dynamic analysis and production management in the Sulige Gas Field.
