摘要
合理降低采注井数比是提高采收率、延长稳产期限的后期调整重要措施之一。本文给出了多方面的研究方法，指出了合理采注井数比存在机理和界线，提出了网格趋向效应对注采系统模拟研究影响的处理方法，并在保砂体的前提下用数值模拟方法分析了各注水井网的开发效果。
It is well known that the reasonable producer-injector ratio in well--network (or well pattern) is very important for the adjustment of the reservoirs in late development stage to improve the oil recovery and to prolong the stable production period. Based on a series of studies in various aspects, the authors analysed the influence of the network effects to the simulation studies of the injection-production system, and the development results of various types of water-injector networks. and then suggested that the rational producer-injector ratio should be within the range of 1 and 2.
