水驱油田进入全面注水开发后，处理好注水问题是原油生产的基础与保障。目前确定水驱油田注水量的普遍方法是依据先定的注采比和产液量目标来计算，受人为因素影响大。以Ｌｏｇｉｓｔｉｃ旋回为基础，建立了油田或区块的综合含水与累积耗水量、综合含水与累积水油比的数学关系，能够求出不同含水时期一定产油量指标所需合理注水量的定量关系式。经实际检验，用此方法计算、规划水驱油田的合理注水量是可行的，还可用此方法规划油田或区块的合理注采比。但是在油田或区块开发未进入全面注水阶段及做重大调整后，不能采用此方法。图３表２参１（郭海莉摘
After the water-flooding oilfield has been fully developed, it is the foundation and guarantee for the production of crude oil to handle the flooding problem well. At present, the common method of determining waterflooding volume in a waterflooding oilfield is based on the first set of injection-production ratio and liquid production target, which is greatly influenced by human factors. Based on Logistic cycle, the integrated water and accumulated water consumption of oilfields or blocks are established, and the mathematical relationship between integrated water and cumulative water-oil ratio can be established to quantitatively determine the reasonable water injection required for a certain oil production index in different water-containing periods formula. After the actual test, using this method to calculate and plan the reasonable water injection quantity of water-flooding oilfield is feasible, and this method can also be used to plan the rational injection-production ratio of oilfields or blocks. However, this method can not be adopted after the oilfield or block development has not yet entered the full waterflood phase and has undergone major adjustments.
