摘　　要：低渗透油藏岩性发育不均匀 ,常表现为多重复合油藏特征。这一特点难以从油井测试资料中观察到 ,而水井测试资料却有所反映。水井测试资料往往存在曲线后期多次上翘现象 ,这些资料的解释具有一定的难度。这表明对于复杂地质条件下的低渗透油层 ,研究非均质储层试井分析理论十分重要。为此 ,建立了多重复合油藏试井理论模型 ,研制出理论图版 ,分析了压力动态特征。列举油水井对应测试的实例 。Low permeability reservoirs often show characteristics of multiple composite reservoirs due to heterogeneous character of formation. The character is difficult to be observed from oil production well test curves, but reflected in water well test curves. The later period regions of water injection well test curves often go up. It is difficult to interpret these data. So, it is important to study well test analysis theory for complex low permeability reservoir.Therefore, this paper presents multiply composite reservoir models. The corresponding type curves are made. The pressure transient characteristics of these type curves are analyzed. Several examples are given to demonstrate the application of the well test theory of multiply composite reservoir.
