摘要
涩北气田储层岩性疏松,纵向上气水层交互,平面上气藏为边水所环绕,气藏驱动类型为边水驱动的背斜型气藏。随着气田的不断开发,水气比不断上升,边水能量逐年增强,水平井出水日趋严重,为提高水平井测试工艺技术,深化水平井开发认识,应用水平井产出剖面测试结果,结合气藏地质特征、气井生产情况,对水平井出水原因进行了分析,针对不同出水部位,提出了开发调控对策,用以指导气井的正常生产,提高采收率。
In Sebei gasfield, most reservoirs composing of unconsolidated lithology are characterized by gas layers interbedded with water layers in vertical, and are surrounded by edge water in horizontal. They belong to anticlinal gas reservoirs with edge-water drive. Along with their constant development, the water- gas ratio raises continuously, the edge-water energy increases year by year,and the water producing from a horizontal well is getting worse. So,this paper analyzes the cause of water production based on the test result of production profile and the geological characteristics. For different parts of water producing, some countermeasures have been made to guide a normal production and to improve the recovery.
