摘要
草舍油田泰州组油藏是典型的复杂断块小油藏。自 1 990年投入注水开发以来 ,采用“河道注水 ,边滩采油”的开采方式 ,原油年产量稳中有升 ,已连续 6年产油量稳产在 2× 1 0 4 t以上 ,采油速度达2 %,提高了水驱控制程度和可采储量。研究表明 ,搞好复杂断块小断块油藏的开发 ,关键在于选择合理的注水井网 ,并辅以转注、深抽、补孔和调层等配套措施 ,才能获得较好的开发效果。
Taizhou Formation Reservoir of Caoshe Oilfield is a small complex fault block reservoir. It started waterflood development in 1990,and adopted the recovery method of 'waterflooding in river channel,oil producing in point bar'. Since then,the yearly production stably went up,and was more than 2×10 4t in 6 successive years. Its oil production rate reaches 2%,and its waterflooding control level and its recoverable reserves are improved. The research shows that the key to develop the small complex fault block reservoir is to choose the reasonable flood pattern and to take the matching measures,such as oil producing wells transferred to water injection well,oil pumping in depth,perforations adding, formation adjusting,and so on. In that case,better developing results could be obtained.
