针对胜利油田目前高含水和特高含水的现状,为适应市场经济对油田开发的要求,确定了极限初产油量的表达式,并讨论了井深、投资、经营成本、油价的变化对它的影响,同时考虑税金、成本上涨率等因素建立了经济极限含水的定量关系式,并对胜利油田老区分高渗透和低渗透两大类对经济极限初产油和经济极限含水进行了测算验证,为油田开发决策和生产运行提供可靠的科学依据。

In order to suit for the demand of market-directed economy in oil field development, it is necessary to study the technological policy limit of the present reasonable development. In the view of economic profit and combination with the practical data of Shengli Oil Field, utilizing the balance principal of gain-lost, this paper develops formulas of the economic limit about production oil and water cut. It also discusses the influence factors on the varying of well depth, investment, manage cost, oil price, economic limit, which include taxation and the going up ratio of cost. This method is used to test and verify the value of the economic limit about initial production oil and water cut in Shengli Oil Field, which is classified to high permeable and low permeable area. The study result may provide a reliable and scientific basis for development policy decision and production.
