摘　　要：注采比能够反映出产液量、注水量与地层压力之间的关系,研究油藏在注水开发过程中的合理注采比,对于稳定原油产量、控制含水上升、实现油田合理高效开发具有十分重要的意义。利用油藏工程方法中的水驱特征曲线和物质平衡原理,对区块长2油藏当前合理注采比进行了研究,并和现场实际数据进行了对比,绘制出地层压力与注采比关系图版。结果表明:两种方法计算的数值和矿场实际的注采比一致,能够指导王家湾区块的整体注水开发。It is very important to study the relationship between the amount of liquid produc- tion, the amount of water injection and the formation pressure, and study the reasonable in- jection and production ratio of the reservoir in the process of water injection. It is very im- portant to stabilize the crude oil production, control the water content rise and realize the reasonable and efficient development of the oilfield the meaning of. Based on the waterflood- ing characteristic curve and the material balance principle in the reservoir engineering method, the current reasonable injection/production ratio of the block Chang 2 reservoir is studied, and the actual data is compared with the actual data. The relationship between the formation pressure and the injection/plate. The results show that the calculated values of the two methods are consistent with the actual injection-production ratio of the mine, and can guide the overall waterflooding development of the Wangjiawan block.
