千米桥主潜山凝析气藏为高饱和、中高凝析油含量的凝析气藏。投入试采以后,具有初期产量较高、压力和产量递减较快、含水上升较快等特点。针对其出水特征,利用动态资料和静态资料相结合的方法,利用产出水矿化度、生产曲线、测井资料、试气资料和地质资料等因素,从多角度综合分析确定出水原因。实践证明,该方法能够有效判断出水层位和出水原因,为制订下一步的防水、控水措施提供依据。
Qianmiqiao main buried hill gas condensate reservoir is a high saturation, high condensate gas condensate reservoir. Into the trial after the trial, with a higher initial production, rapid decline in pressure and yield, water cut faster and so on. In view of the characteristics of its effluent, a combination of dynamic data and static data is used to determine the cause of effluent from a multi-angle comprehensive analysis using such factors as the salinity of produced water, production curve, logging data, test gas data and geological data. Practice has proved that this method can effectively determine the cause of the water layer and the water outlet, and provide the basis for making the next water-proof and water-control measures.
