摘　　要：本文建立了多油层径向单相不稳定流条件下油井地层压力计算的差分模型。实例计算表明，各分层压力的平均值能较好地逼近全井地层压力，其相对误差为０．１％左右。Difference model for calculating formation pressure of oil wells at multireservoirsingle phase unstable radial flow condition is established.Case calculation shows that the av-erage value of each separate layer pressure is nearly about the formation pressure of thewhole well with relative error of about 0.1%.
