摘    要：为了进行塔里木盆地储量经济评价,需 要准确预测油井的产能.作者根据陈元千的理论研究成果,在井底流动压力低于饱和压力时,利用测试的生产井日产量和相应的流动压力求取饱和压力以上的采油指数；同时,用高于饱和压力下的采油指数,求取低于饱和压力下不同井底流动压力条件的采油指数,从而较为准确地确定生产井的产能,为油田开发提供了理论依据.

Abstract: It is necessary that the productivity of the oil wells is predicted accurately in order to evaluate the oil reserves in the Tarim Basin. Based on the theory of Mr Chen Yuanqian′s study, when the flowing pressure at the bottom of well is lower than saturated pressure, the exponent of oil extraction above saturacted pressure can be gotten by testing daily yeild and flowing pressure in productive well. The exponent of oil extraction below saturated pressure and the different flowing pressure can be obtained by using the exponent of oil extraction above saturated pressure, then the productivity of working oil well can be determined accurately for the development of the oil field.
