摘　　要：合理井网密度的确定是油田开发规划的核心内容。油田注水开发效果与井网密度有关,而油田建设的总投资中钻井成本又占相当大的比例,因此井网密度对注水开发的经济效益有很大影响。以延长油田松树林新窑区松700井区为例,根据谢尔卡乔夫采出程度与井网密度的关系,并依据投入产出原理,考虑单井总投资额(包括钻井、地面和设备费用),建立计算合理井网密度的经验公式,从而指导超低渗油田合理井网密度的确定。To determine the reasonable well spacing density is the core content of oilfield development planning.The well spacing density impact the economic results of waterflooding extraction significantly,because oilfield waterflood effect is relevant to the well spacing density and in the total investment of oilfield construction,the drilling costs accounts for a considerable proportion.Based on the case study of Songshulin-Xinyao Song 700 area of Nanniwan oilfield,according to the relationship between recovery percent of reserves and well spacing density and input-output theory,considering the total single well investment,empirical equation could be built to calculate the reasonable well spacing density,thus guiding the ultra-low permeability oilfield well spacing density confirmation.
