如何确定一个油田的开采深度(或开采周期)是石油生产决策的重要问题。合理的开采深度必须考虑两个因素:一是石油生产计划任务,一是最佳经济效益。本文在分析了油田开采决策的三个特点的基础上,利用盈亏分析原理,对确定油田最佳开采量(或合理的开采周期)进行了初步探讨。并用推导出的理论模型,从宏观上定性讨论了石油计划指标体系的改革问题。 How to determine the exploitation depth (or mining cycle) of an oil field is an important issue in oil production decision-making. Reasonable mining depth must consider two factors: First, the task of oil production planning, first, the best value for money. Based on the analysis of the three characteristics of oilfield exploitation decision-making, this paper makes a preliminary discussion on the determination of the optimal exploitation quantity (or reasonable mining period) of the oilfield by using the principle of profit and loss analysis. And qualitatively discussed the reform of the oil planning index system from the macroscopic level with the theoretical model deduced.
