油田油井增产措施经济极限分析研究

在油田开采中后期,随着油田开发程度的加深,措施作业边际产量递减,措施作业边际费用递增,措施作业增量边际成本递增。通过对中后期油田油井措施作业边际产量递减规律,措施作业边际费用递增规律,措施增量边际成本递增规律的分析,把措施费用看作一项再投资,运用投入产出分析的原因和经济极限产量计算的方法,以油田单井增产措施为分析对象,提出了油田油井增产措施经济极限的分析模型。这对中后期油田油井开发经济效益的分析和关井时机的选择提供了依据。

THE STUDY ON ECONOMIC LIMITATION ANALYSIS FOR OIL WELL OUTPUT ENHANCEMENT

In the middle-late stages of production, as the deepening of the oil field development, the marginal operation output decrease, the cost increases, and the investment increase, too. Through the analysis of the laws of the marginal operation output decreasing, the cost increasing, and the investment increasing in the middle - late stages, the operational cost is looked upon as a re-investment, by means of input and output analysis and economic limitation output calculation, the analytical model of oilwell output enhancement lim-itation is worked out taking single well output enhancement as example, which provides alternations to economic effect analysis and shut down time of oil well production in the middle-late stages.
