摘　　要：渗透率变异系数是描述油藏非均质性的一个重要参数,矿场统计方法分统计学理论公式法、Dykstra-Parsons(1950)经验公式法,每种方法各有其优缺点和适用范围。通过对大庆油田南一区东块不同方法、不同种类变异系数统计结果对比分析认为,在变异系数对比分析时,应对同种统计方法得出的变异系数进行对比,以确保结果的准确性。Permeability variation factor is a key parameter to describe reservoir heterogeneity. Field statistics includes the statistic theory equation and the empirical equation method proposed by Dykstra-Parsons in 1950, and each method has its own advantages and disadvantages as well as specific application scope. This paper presents the different variation factor statistic results for the east block of South District-I in Daqing oilfield using the different methods. The study shows that comparison between the factors given by the same statistic method is a good way to ensure a correct result.
