用压力幂数法预测油井的产量

APPLICATION OF PRESSURE POWER METHOD TO PRODUCTION OF OIL WELLS

文中简介了不同压力条件下的压力幂数法预测产量公式的导出、预测步骤,以及转抽和调参的预测实例。通过对大庆油田61口井的预测实践表明,该方法与PI-IPR法及相对采油指数法比较,平均误差较小,按其预测产量结果选泵和调参效果较好。

This pape briefly describs the use of the pressurepower method, under the circumstances of different pressures, to derivate the production prediction equation and the steps of production prediction,it also illustrates with examples the predict ion of oil production for putting on pump and changing parameters. The results of production prediction, taken from 61 wells in the central area ot Sartu Oil-Field, show that the pressure power method has a smaller mean error than those of both the PI-IPR and the relative recovery index method, thus both selecting the pumping rate and adjusting parameters are more effective, according to the resu lts of production prediction.
