摘　　要：以玉门油田分公司一老油田为例,在总结前人研究的基础上,用解析方法和经济评价方法推导出一种计算投入开发若干年后的油田(油藏)合理井网密度和极限井网密度的方法。该方法不仅考虑了投资的利息,还考虑了逐年管理费用和原油销售收入的利息。该方法可对投入开发后的油田(油藏)井网是否加密的可行性进行论证,使决策者最大程度地避免投资风险。Based on available approaches in analysis and economical evaluation, a new method for calculating reasonable and ultimate well spacing density in an old oilfield of Yumen that has been developed for many years. It takes into account both interest from investment and interests from overhead expenses and crude-selling income year after year. This method can be applied to verify the feasibility of infill drilling in an old oilfield or reservoir, getting rid of taking a risk for uncertain investments.
