摘　　要：双河油田目前已进入高含水开发后期,稳定产量就成了开发的首要任务。补打调整井是稳产的工作之一,此时确定布井数量和井网的合理密度成为工作的重点。通过运用谢尔卡乔夫公式建立了井网密度与采收率关系模型,确定了合理井网密度的技术经济政策界限,为油田的产量稳定提供了坚实的理论基础。Since the development of Shuanghe oilfield,different development manners have been adopted to enhance oil recovery, from water flooding to primary and secondary well pattern thickening.However,when the oilfield enters into later stage with high water cut,the stable production will become the primary task of development and then the drilling of new wells will be the key to realize it.Therefore,the number of new wells and rationality of well spacing density will be of great importance.By means of Karasseff formula, the relation model between well spacing density and oil recovery, and economic and technical limit of rational well spacing density have been established in Shuanghe oilfield, which will provide a solid theory foundation for stable production of oilfield.
