火山岩气藏面临的出水问题及治理对策

随着气田开发进入稳产阶段末期，气井出水带来的开发矛盾日益突出。为此，在认识火山岩储层4种出水类型规律的基础上，开展典型气井生产动态特征分析，明确不同出水类型气井面临的治水难题。通过现场试验，探索出经济可行的治理对策，包括裂缝纵向强水窜型气井连续循环气举、裂缝纵向弱水窜气井智能化泡沫排水采气，以及孔隙纵向水锥和高含水饱和度气层出水气井储层深部解水锁3种治理措施，为火山岩气藏的持续高效开发提供技术支撑。

The Problem of Water Production in Volcanic Gas Reservoir and Its Dealing Measures

With the development of volcanic gas reservoir entering the end of stable production stage, the contradiction of gas well water production is becoming more and more serious. Based on the understanding of four types of water production in volcanic reservoirs, the production performance characteristics of typical gas wells and clarifies the problems of water control in different types of gas wells are analyzed. Through the field test, the economical and feasible treatment measures are explored, including continuous gas lift of longitudinal strong water channeling gas wells and intelligent foam drainage gas production of longitudinal weak water channeling gas wells with fractures, as well as pore vertical water coning and high water saturation gas reservoir water well deep water release lock three treatment measures, in order to provide technical support for the continued efficient development of volcanic gas reservoir.
