油田效益产量计算方法探讨

Method for Calculation of Oilfield Profit Production

为了合理制定油田产量计划指标,使油田开采获得最佳效益,从油田开展单井效益评价出发,依据油田产量的经济特征,将效益产量分为新井效益产量、老井效益产量和措施效益产量。新井效益产量计算方法为现金流量法,将新井作为建设项目评价其经济性,求解净现值最大时的产能建设规模及当年新井产量;老井效益产量计算方法为单井贡献值法,从单井的收入扣除变动成本后对油田效益的贡献大小进行评价,求解老井利润最大时的产量;措施效益产量研究方法是依据投入产出法对措施产出的增量价值的经济性进行评价,然后求解利润最大时的措施产量。针对新井、老井、措施提出了油田效益产量计算模型,模型解决了油田配产中只注重产量指标、忽视油田效益的状况,实现油田效益配产。

The oilfield evaluated the economic performance of a single well in order to make a reasonable plan for production targets and optimize the oilfield production. Based on the economic characteristics of the oilfield production, the profit production is divided into the profits from new wells, old wells and stimulation measures. The method for calculation of a new well’s profit production is cash flow method, which takes a new well as a construction project and evaluates its economic performance. It is focused on construction scale of productivity and the new well’s production of the year at the time of net present value. The method for calculation of an old well’s profit production is single-well contribution value method, which evaluates the contribution to the economic performance of the oilfield from a single well’s revenue with the changing cost deducted. It is focused on the old well’s production at the time of its maximum profit. The research method for economic production from the stimulation measures is based on the input-output model to evaluate the economic performance of additional value from the stimulation measures. It is focused on the stimulated production at the time of maximum profit. This paper comes up with the calculation models of the oilfield profit production for new wells, old wells and stimulation measures. Those models help the oilfield bring about good economic performance of production, solving the problem that the oilfield only focuses on production target while neglecting the economic results in its production plan.
