摘　　要：针对长垣外围油田地质情况,以升平油田、龙虎泡油田萨高合采井区和朝55区块作为典型研究对象,通过规范注采系统适应性条件与原则,优化合理注水方式。运用三种数学方法求得平均油水井数比,确定合理油水井比界限,并制定合理转注方式,形成了适合于长垣外围油田在中高含水时期的精细注采系统调整技术。矿场实验结果表明,精细注采系统调整技术的实施获得了比较好的改善效果和收益。This paper is focused on the geological conditions of Changyuan Peripheral Oilfield. The study drawing on the typical examples of Shengping, Longhupao oilfield and 55 block of Chao consists of optimizing reasonable water injection by regulating suitability conditions and principles of injection-pro- duction system; determining the average ratio of oil-water Wells number, a reasonable limit of oil-water Wells number, and developing a reasonable mutually explanatory manner using three mathematical meth- ods; developing fine injection-production system adjustment technique suitable for Changyuan peripheral oilfield in medium and high water cut period. Field test results show that fine injection-production system adjustment technique provides a better performance and profitability.
