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。
In view of the present situation of high water cut and extra high water cut in Shengli Oilfield, in order to meet the requirements of market economy for oilfield development and ensure the economic benefits of oilfield development, it is necessary to study the current rational economic limit well pattern density. Based on the actual production data of Shengli Oilfield, this paper establishes quantitative relationship between oil recovery rate and well pattern density. Considering well capital construction investment and production and operation costs within the investment recovery period, this paper uses the principle of breakeven, A reasonable well densitometric density expression is derived. The rational economic limit well density of 50 high and low permeability units in Shengli Oilfield is calculated and verified, which provides a reliable scientific basis for oilfield development decision-making and production operation.
