多段塞复合调剖工艺在火烧山裂缝油田的研究与应用

针对火烧山油田开发面临的水淹水窜问题,结合火烧山油藏的具体特征,应用油藏工程和采油工程研究方法,在室内实验的基础上,开展矿场试验,分析试验结果,不断调整并优化调剖方案。2009年在火烧山H2、H3、H42油藏采用多段塞复合调剖工艺共计24井次。实施结果表明该工艺与火烧山油藏适应性较好,能有效对大裂缝、大孔道水窜通道进行封堵,并能有效的控制油田含水上升,对油田的稳油控水起到了积极的作用。截止2009年11月底累计增油5406.9t、累计降水3451.6t。

Research and application of compound profile control technology with multi-slug in fractured reservoir of Huoshaoshan oilfield

Aiming at the problems of water flooding and water channeling in Huoshaoshan oilfield, in combination with the specific characteristics of the fractured reservoirs in Huoshaoshan oilfield, by adopting the research method of reservoir engineering and production engineering, based on the laboratory testing, field testing and its testing results has been carried out and analyzed. Therefore, the profile control technology has been optimized. The compound profile control technology with multi-slug has been adopted in Huoshaoshan oilfield many times and the application results indicate the technology has a good adaptability and can effectively seal the big fractures and water channel with large pores and control the increasing water cut. By the end of November 2009, the accumulated increased oil, decreased water and effective days are 5406.9 t, 3451.6 t and 5918.3 t respectively.
