摘　　要：针对胜利油区目前高含水和特高含水的现状 ,为了适应市场经济对油田开发的要求 ,确保油田开发获得较好的经济效益 ,有必要对目前的合理经济极限井网密度进行研究。本文从经济效益的角度出发 ,根据胜利油田的实际生产资料 ,建立了采收率与井网密度的定量关系 ,考虑井的基本建设投资和投资回收期内生产经营费用 ,利用盈亏平衡原理 ,解出合理井网密度的表达式 ,并对胜利油田高渗透和低渗透两类共 5 0个单元的合理经济极限井网密度进行了测算验证 ,为油田开发决策和生产运行提供可靠的科学依据。According to the present situations of high and special high water-cut in Shengli Oilfield,in order to suit for the demand of market economy to the oilfield development,and obtain better economic profit,it is necessary to study the technological policy limit of the present reasonable development.In the view of economic profit,using the practical data,regarding the basic construction investment and production funds in invest payout period,utilizing the balance principal of gain-lost,this paper proposes the quantity relationship between recovery and well spacing density,and develops the formula of the reasonable well spacing density.This method is used to test and verify the value of the reasonable economic limit of well density for 50 units in Shengli Oilfield,which is classified into high permeable and low permeable ones.The results of the study may provide the reliable and scientific basis for development policy decision and production.
