衰竭式开发油藏产量递减规律预测方法及应用

Prediction of Production Decline of Depleted Reservoir and Its Application

为满足新油田选择采油方式时对不同时期油井产能数据的需要 ,从油层岩石的压力敏感性试验结果出发 ,首先导出采液指数变化规律的预测方法 ,从而确定出油井的供液能力 ;再结合井筒举升能力预测不同举升方式下油井的产量变化规律。

To meet the needs of oil-well productivity data in different period of selecting production modes in a new oilfield, in consideration of the experiment result of rock pressure sensitivity.a method for predicting the change rules of fluid productivity index is derived to determine fluid supplying capability in combination with well lifting capability, the production decline rules in different lifting modes are predicted. Application example is provided.
