摘要
胡尖山油田A201油藏主力开发层系为长6油层,2009年投入开发,开发井网形式为480 m×150 m菱形反九点井网,经多年注水开发后,区内出现不同长度的贯穿裂缝,表现出主向油井水淹,侧向油井不见效,油藏开发效果差。本文对A201区长6油藏开发特征及储层进行精细解剖,建立三维地质模型,开展数值模拟研究,精细刻画剩余油分布规律,提出下步剩余油挖潜建议,改善油藏开发效果。
The main development layer of A201 reservoir in Hujianshan oilfield is Chang 6 reservoir, which was put into development in 2009. The development well pattern is 480 ×150 m rhombic anti nine point well pattern. After many years of water injection development,there are different length through fractures in the area, showing that the main oil wells are flooded, the lateral oil wells are not effective, and the reservoir development effect is poor. In this paper, the development characteristics and reservoir of Chang 6 reservoir in A201 area are carefully dissected, three-dimensional geological model is established, numerical simulation research is carried out, the distribution law of remaining oil is finely depicted, and suggestions for further remaining oil potential tapping are put forward to improve the reservoir development effect.
