摘　　要：油藏的水驱开发效果与自身地质条件有关,但受人为因素影响更加深远。人为主观因素选择的开发方式决定了一个区块最终采收率的大小。因此,及时有效的调整开发方式,为最终提高采收率打下基础,是重中之重。文章从可采储量、水驱储量动用程度、采出程度以及水驱指数进行预测油区进行小规模注水对区块整体开发效果的影响,分析油区目前的开发效果及对今后的预测,并对目前进行规模注水后区块的开发效果及措施改造效果进行了评价,为下一步油区的水驱开发指明了方向。The water drive development effect of a reservoir is related to its own geological conditions,but it is more profoundly affected by human factors.The development method selected by human subjective factors determines the size of the final recovery factor of a block.Therefore,timely and effective adjustment of development methods to lay the foundation for the ultimate improvement of oil recovery is the top priority.Predict the impact of small-scale water injection in the oil area on the overall development effect of the block from the recoverable reserves,the degree of production of water flooding reserves,the degree of recovery,and the water flooding index,analyze the current development effect of the oil area and the future forecast,and At present,the development effect of the block after the large-scale water injection and the effect of the improvement of measures have been evaluated,which points out the direction for the next step of water flooding development in the oil area.
