摘要： 涩北一号气田是中国目前最大的疏松砂岩气田,气水层交互,层数多而薄,边水环绕,开发过程中出水现象普遍,气井控水是该气田开发的技术难题之一。在气藏精细地质描述的基础上,研究了该气藏某层系单井产水、产气曲线特征、水气比及上升规律,分析了主要水源及出水原因,将该层系出水类型归结为4类,即低产水稳定型、低产水缓慢增长型、中产水快速增长型和高产水急剧增长型,根据不同类型井的出水状况,提出有效措施进行分类控水,现场应用取得良好效果。

Abstract: Sebei No.1 gas field is now the largest unconsolidated sandstone gas field in China, with alternative gas and water layers, multi-thin layers and edge water. In the gas field development, the gas wells often produce water, so the control of water production is the one of the technical problems. This paper, on the basis of fine description of gas reservoirs, studies the characteristics of water production and gas production curves, water gas ratio value and its increased law to all wells in one layer of the gas reservoirs, analyzes the main water sources and the cause of water production. The water production in these wells is classified into four types, namely, the low water yielding and stable type, the low water yielding and slow growth type, the moderate water yielding and fast growth type and high water yielding and sharp growth one. According to the water production situations in different types of wells, the effective measures for water control are proposed by the classification. Field application of the measures showed good results.
