茌平构造带处于鲁西隆起西北倾伏区的中部,是被带内次级断层复杂化的呈北北东向展布的断层背斜带。本文系统分析了该带构造演化特征及原生油气成藏条件:三叠纪末挤压隆起,早中三叠世地层广遭剥蚀,同时产生了兰聊断层,在兰聊断层控制下,茌平构造带定型于燕山期(喜山期以整体抬升为主,带内次级断层基本停止活动),这对古生界烃源岩二次成烃与圈闭形成的时间配套条件较为有利。本区发育有下古生界开阔(局限)海暗色(泥)灰岩和上古生界煤系两套烃源岩,下古生界顶风化壳作为良好储层,构成了自生自储成藏组合,油气远景的关键在于盖层,该带C-P残留区油气勘探远景较好
The Pingping structural belt is located in the central part of the northwestern subsidence area of the Luxi Uplift and is a fault anticline belt that is complicated by north-north eastward extensional faults. This paper systematically analyzes the tectonic evolution characteristics of the belt and the conditions for the formation of the protolith oil and gas. At the end of the Triassic, the Cretaceous was crushed and uplifted, and the Triassic strata were extensively denuded in the early Middle Triassic. At the same time, the Lanliao fault was formed. Under the control of the Lanliao fault, The tectonic belts were settled in the Yanshanian period (the whole Himalayan period was mainly uplifted, and the secondary faults in the belt basically stopped their activities), which provided favorable conditions for secondary hydrocarbon generation and trapping of the Paleozoic source rocks. There are two sets of source rocks of the open (limited) sea dark mud (mudstone) and coal measures of the Upper Paleozoic in the Lower Paleozoic, and a metamorphic shell of the Lower Paleozoic as a good reservoir, forming a spontaneous self-accumulation reservoir The key to the combination and hydrocarbon outlook lies in the caprock, which has a good prospect for oil and gas exploration in the C-P residual zone
