摘　　要：大庆外围探区多为低渗透层,大多采用常规试油,不进行地层测试,得不到地层压力资料,需要有一种方法在不知地层压力的情况下评价油藏。双产量法是利用两种工作制度下的产量及相应的流压,求得油藏平均压力,再预测不同流压下的产量,绘制IPR曲线,进行油藏评价。经过实际验证,方法可行。Conventional oil testing is usually used without well testing at many low permeability reservoirs in the periphery of exploratory regional of Daqing oilfield,which can not get formation pressure data.Therefore,a kind of new method to evaluate reservoir is needed.By production and flowing pressure on two kinds of work system,double production method can get average reservoir pressure,and predict production at difference flowing pressure,and draw IPR curve to evaluate reservoir.Practical example shows that this method is workable.

关 键 词：双产量 IPR曲线 油藏评价
