摘　　要：复杂断块油藏由于受不同方向断层切割而形成大小不一、形态各异、断层上下盘相互分隔、彼此独立的封闭单元。其复杂性不单表现在十分破碎的形态上,更主要的是主断裂控制了油气的富集规律,与主断裂相伴生的一系列断层造成了油藏多重复杂性,油气发生多次运移和聚集,纵向上形成多套含油气层系,平面上断块之间含油性差异较大,为勘探开发带来了极大的难度。该文针对王官屯油田含油层系多、圈闭类型多、断块破碎、油气运移与分布复杂的特点,应用系统分析的方法对王官屯油田复杂断块储集层、圈闭类型、油气成因与分布等要素进行研究,深化油藏形成与分布规律认识,对复杂断块成藏条件、油藏组合模式进行系统归纳,建立一套复杂断块油藏组合模式,并指导王官屯油田滚动勘探开发,取得了较好的效果。Complex fault block reservoir is split by faults of different orientation to form independent closed geology units with different sizes, different shapes, separated upthrowns and downthrowns. The broken configuration only shows a part of the complexity, the more worse situation is that the main fault controls the rules of oil and gas accumulation. A series of accompanying faults lead to multi complexity of reservoir and hydrocarbon migrated many times, so many sets of oil-bearing layers are formed vertically and there has great difference in oiliness between blocks. It is very difficult to exploration and development of this kind of reservoirs. According to the characteristics of Wangguantun Oilfield, which are of many oil-bearing strata, trap types and shatter blocks complex migration and distribution of hydrocarbon, the paper gaves a systematic analysis to the study on reservoir, trap types and hydrocarbon origin and distribution. The paper also summarizes the forming condition and distributing pattern of reservoirs, the accumulating conditions of complex faulted blocks and reservoir combining models. A set of combined patterns for complex fault block reservoirs are set up, which can gave a guidance in the rolling exploration and development of Wangguantun Oilfield. Favourable effect has been obtained.
