确定油田经济产量的最低运行费用法

The minimum operation fee determination for economical oilfield production.

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

Most of the oilfields in China have entered into the mid late production period. Production decline is inevitable. The increasing production cost has direct influence on the economical benefit. The economical production is the production when balance is achieved for revenue and cost, i.e., profit is zero. The minimum operation fee method is to calculate the economical production by determining the minimum operation fee of a single well from the production strategic point of view. When the after tax revenue of well production equals the minimum well daily cost, the well daily production is the economical production; however, when the after tax revenue of a single well can not compensate the minimum operating fee for normal work, the daily production is non economical. This method considers the geological parameters and also the economical parameters.
