摘　　要：容积法计算石油地质储量过程中,斜井有效厚度的计算对储量计算结果的影响较大。本文阐述了三种条件下有效厚度的计算方法:即小倾角地层斜井有效厚度计算方法,大倾角地层逆倾向斜井有效厚度计算方法,和大倾角地层顺倾向斜井有效厚度计算方法。并对临盘油田唐7-斜60区块进行了实例计算。计算结果表明:大倾角地层斜井储量计算过程中,必需考虑地层倾角对有效厚度及储量的影响。In the process of estimating geological petroleum reserves by volumetic method,the effective thickness of a deviate well has great influence on the result.The paper gives the methods of net pay thickness calculation under three conditions:calculation of small formation dip angle,calculation of large formation dip angle of countertrend deviated wells,calculation of large formation dip angle of along the inclinedslope.Block Tang7-xie60 is chosen for an example.The results show that large formation dip angle should be considered when calculating reserves using the net pay thickness
