【Abstract】 According to the seepage flow mechanics, we obtained the relational expression, through which we can work out the producing test rate, between producing test rate and pressure difference. We established quantitative relationship between stable oil well productivity and producing test productivity by combining with the productivity data from several development regions of peripheral low permeability oil field in Daqing. Both are linear. And we have calculated the stable productivity of wells in P-layer and FY-layer by using the relationship obtained. We forecast the rate of productivity index is 0.116,comparing the producing test rate, the relative error is 8.66%. It means that the expression can be used in production forecast of developed oil field and development planning of a new oil field.更多还原
