摘　　要：油气储层形成过程中因受到沉积环境、成岩作用及构造作用的综合影响,无论在空间分布还是储层内部各个属性上都会存在极不均匀的变化,这种变化称为储层非均质性。储层非均质性是影响油、气、水运移及油气采收率的重要因素。研究考虑非均质性的规模影响在储层开发生产中是必不可少的。本文以渭北油田长3-长8储层为例,利用储层变异系数、突进系数对碎屑岩储层层间非均质性、层内非均质性做详细研究。In the process of oil and gas reservoir forming by sedimentary environment,diagenesis and tectonism comprehensive effects,uneven exist within both the spatial distribution and the reservoir property of each changes,this change is called the reservoir nonhomogeneous.Reservoir nonhomogeneous is an important factor of oil and gas recovery factor.Study and consider about the size of the nonhomogeneous impact in reservoir development and production is necessary.Take Wei Bei oil-field Chang3-Chang8 reservoirs as example,detailed research clastic rock interbedded nonhomogeneus and intraformational nonhomogenous base on the max-mean coefficient and variable coefficient of reservoirs.
