摘　　要：东河砂岩油藏为一块状砂岩油藏,夹层和边底水发育,开发方式以水平井为主,直井为辅,初期纯油区和过渡带均利用天然能量开发,纯油区转注后为注水与天然能量联合驱动开发。油藏开发初期产量高,含水上升慢,进入中高含水期后,含水迅速上升,产量急剧递减。经对比研究后采用丁型水驱类型测算油藏产油量、含水率、可采储量等开发指标,达到了较高的预测精度,为油藏开发效果评价、调整方案编制及开发规划提供了可靠依据。Donghe sandstone reservoir in Hadeson oilfield is a massive sandstone reservoir with interlayers and edge-bottom water. Horizon- tal well is the main recovery process integrated with vertical well. Depletion process is adopted in pure oil zone and transitional zone during the preliminary stage, followed by combined process of depletion with artificial water injection. In view of preliminary-stage high produc- tion, low water cut, and mid- to late-stage high water cut and rapid production decline in this reservoir, this paper conducted the compara- tive analysis of the water drive characteristic and the production performance, showing that Type-D water drive characteristic is more suit- able for the reservoir, and using Type-D curve to calculate the development indexes such as production rate, water cut, recoverable re- serves, etc. can give high forecast precision of them, which have provided a reliable basis for exploitation effect evaluation, adjustment scheme compilation and development planning.
