| 摘 要： | 根据水驱开发油田合理油水井数比和注采比的准确定义,由极值原理,详细推导了油水井地层压力相同和不同时油田合理油水井教比的计算公式.该公式不仅适用于注采平衡条件下油田合理油水井数比的计算,亦适合干非注采平衡条件及低渗透油田合理油水井数比计算.以往采用的算法均存在缺陷:"吸水、产液指数法"建立在注采平衡基础之上,"吸水、产液...

| Abstract: | According to the accurate definition of the reasonable production-injection well ratio and injection-production ratio for waterflooding oilfields,the formula of the reasonable production-injection well ratio under the same or different formation pressures between oil well and injection well is derived based on the principle of extreme value.The formula can be used in the balanced or unbalanced injection-production system such as reservoirs in high water cut stage or low-permeability reservoirs.All the previ... |

| Keywords: | waterflooding injection-production ratio reasonable production-injection well ratio injection-production equilibrium low-permeability reservoir |
