随着苏里格气田的持续开发,气井地层能量逐渐下降,携液能力减弱,“积液”问题成为提高气井产量的最大生产瓶颈。本文分析了气井积液的原因,阐述了积液井判断方法,结合单井生产动态把积液井分成四类,针对苏10井区积液井主要采取了打捞节流器、强排、间开、间关和泡沫排水采气管理措施。在实践中证明,打捞节流器措施在短时间内有一定效果;强排措施是最直接、最有效的方法之一;间开措施能减缓产量下降速度;间关措施是一种主动的排液措施,对于前期积液井效果明显;泡沫排水采气措施能有效增加气井携液能力,提高单井产量。最后得出积液井管理是一项系统工程,需要各种措施相互结合,才能有效“排液”。
With the continuous development of the Sulige gas field, the energy of the gas well gradually decreases and the liquid carrying capacity weakens. As a result, the problem of “effusion” becomes the biggest production bottleneck to increase gas production. This paper analyzes the causes of gas well fluid, expounds the judging method of accumulating fluid well, and divides the fluid accumulation wells into four types according to the single-well production dynamic. According to the fluid accumulation wells in Su 10 well, Open, customs clearance and foam drainage gas management measures. In practice, it has been proved that the measures of salvaging the throttle have a certain effect in a short period of time. Strong barging measures are one of the most direct and effective ways. Inter-measure measures can slow down the rate of yield decay. Customs clearance measures are an active bar Liquid measures, the effect is obvious for the pre-fluid well; foam drainage and gas recovery measures can effectively increase the carrying capacity of the gas well and improve the single-well production. Finally concluded that fluid well management is a systematic project that requires a combination of various measures in order to effectively “drainage ”.
