我国大部分老油田已进入注水开发中后期 ,产量递减不可避免 ,油气开采成本逐年递增 ,直接影响着油田的经济效益。最低运行费用法从生产决策的角度出发 ,以油井为计算单元 ,通过确定单井的最低运行费用来计算油田的经济产量。单井日产油量的税后收入与维持油井正常生产所必须的最低日消耗费用刚好持平时 ,其日产油量就是该井的经济极限产量 ;而当日产油量的税后收入低于最低日运行费用时 ,其日产油量则为单井无效益产量。这种方法既涉及油田的地质开发参数 ,又考虑了目前的经济技术参数。参 3
Most of the old oilfields in China have entered the middle and late stages of waterflood development. The declining production is inevitable. The cost of oil and gas exploration increases year by year, directly affecting the economic benefits of the oilfield. Minimum operating cost method From the perspective of production decision-making, taking the oil well as the calculating unit, the economic output of the oilfield is calculated by determining the minimum operating cost of the single well. When the post-tax income of a single well is equal to the minimum daily consumption cost necessary to maintain the normal production of the well, its daily oil production is the economic limit output of the well; and the daily after-tax income of oil production is below the minimum day Operating costs, its daily oil production is single-well ineffective yield. This method involves both the geological development parameters of the oilfield and the current economic and technical parameters. Participation 3
