H油田J油藏相渗曲线计算新方法及应用

A new method tOcalculate relative permeability curve and theapplication in J reservoir of H oil field

根据油田实际生产动态数据,借助于多元线形回归[1],推导油水两相相对渗透率与含水饱和度的定量关系,进而求取无因次采油、采液指数,计算结果与油井生产动态相符,为油田后期提液提供理论依据,有效延缓油田产量递减。

By means of multi-variable linear regression method,the field dynamic production data is used tOderived the quantitative relationship between oil and water relative permeability and water saturation.Then dimensionless oil/liquid productivity index can be further derived.The calculated results of this method are matched quite well with the actual oil well dynamic production data.This method can provide theoretical basis for improving the oil field liquid production in the late stage of oil field development,which would effectively delay the oil field production decline rate.
