摘　　要：受地质情况、井网条件、配产、流体物性的影响,在实际油藏实现完全均衡驱替是不可能的。对于非均质油藏,必须最大限度地追求相对较高的均衡驱替,实现原油最大采出效益。数值模拟研究表明:井距和配产对注采井组均衡驱替有很大影响,且同一地质模型,存在一个无因次均衡驱替井距和产量;利用渗透率极差对无因次均衡驱替井距和产量的影响,可确定非均质油藏最优井距和最佳配产。With the impact of geology,well patterns,allocation and fluid properties,it is impossible to achievecomplete equilibrium displacement for actual reservoirs.However,a relatively high balance displacement must bemaximally pursued so as to attain maximum oil recovery efficiency for heterogeneous reservoirs.According to thenumerical simulation researches,well spacing and allocation have greatly influenced on equilibrium displacementof injection-production well group,and the same geological model has a dimensionless equilibrium displacementwell spacing and production;finally permeability range has an effect on the dimensionless equilibrium displacementwell spacing and production,then optimal well spacing and allocation is determined,which supplies a theoreticalreference for balance displacement effects of injection well group.
