英152区块为天然水驱构造油藏,曾是英台油田上产百万的主力贡献区块。进入特高含水开发期后,由于潜力资源日益枯竭,同时边底水的逐渐侵入,区块开发面临递减大,含水上升快,措施挖潜难等瓶颈问题,而通过油藏避射、合理流压研究来控制油藏边底水的推进速度,依靠沉积相、数值模拟、油水界面位置研究等手段,明晰地下油水运移规律,深挖措施潜力,最终实现天然水驱油藏在特高含水期的综合稳产。
Block 152 is a structural reservoir for natural waterflooding and was the main contributor to millions of units produced in the British Taiwan oilfield. After entering the development period of ultra-high water-cut, due to the depletion of potential resources and the gradual intrusion of edge-water, the development of blocks faces bottlenecks such as decreasing, rapid rising of water cut, Based on the study of sedimentary facies, numerical simulation and oil-water interface study, we can clarify the law of underground oil-water migration and tap the potential of the measures to realize the natural water-flooding reservoir in the ultra-high water-cut period The comprehensive and stable production.
