摘要
针对五里湾长6油藏面临常规改造措施针对性和有效性逐年变差,且含水上升快等技术难题,开展暂堵压裂工艺优化研究,进行工艺思路和参数优化,配套完善压裂液体系,形成五里湾长6油藏暂堵压裂优化技术。现场应用实践表明,该技术提高重复压裂技术的针对性和有效性,丰富了老油田措施手段,抑制了含水上升,提高单井产能,对五里湾长6油藏长期稳产具有重要意义。
Due to the gradual deterioration of pertinence and effectiveness of conventional stimulation technique in Chang 6 reservoir at Wuliwan deteriorated in past years,and the fast increase in water production,the temporary-plugging fracturing technique was studied to get optimum stimulation process and parameters,to improve fracturing fluid system,and to set up a fracturing technology suitable for Chang 6 reservoir at Wuliwan.Field application showed that this technique could improve the effectiveness of the secondary fracturing,providing extra means for secondary stimulation,the water production was inhibited,and single-well production increased.It is significant for long time stable production out of Chang 6 reservoir at Wuliwan.
