超低渗油藏合理井网密度确定——以南泥湾油田松树林新窑区松700井区为例
Journal of Chongqing University of Science and Technology(Natural Sciences Edition)(2013)
Abstract
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。
