摘　　要：通过对孤西断裂带下古生界褶皱块断型潜山油藏的综合研究,总结出孤西潜山带经历印支期挤压逆冲、燕山期拉张负反转和喜马拉雅期拉张断裂改造3个构造演化阶段,形成了受北西向孤西断裂控制的内幕褶皱块断型潜山带,发育了不整合面风化壳型、潜山内幕孔洞型和构造裂缝型3种储集层类型,进一步厘定了高潜山和低潜山2大类5种潜山油气成藏模式,其中高潜山油气藏模式有风化壳型、反向断块内幕型和地层不整合型,低潜山油气藏模式有反向断块和顺向断块型2种,这对济阳坳陷潜山勘探及多样性潜山理论的完善具有重要意义,为实现成藏规律指导下的潜山勘探奠定了基础。According to a comprehensive study of the early Palaeozoic reservoirs in the Guxi fold-block buried hill fault zone, it is suggested that the Guxi buried hill zone underwent three main forming-evolving stages: extruding and thrusting stage in the Indonisian period, pulling apart and reversing counter stage in the Yanshanian period and fault recreating stage in the Himalayan period. The Guxi fault zone, controlled by the Guxi fracture in the north direction, has three reservoir types, including unconformity weathering crust, internal cavern of buried hill and structural fracture. In addition to high and low Buried Hills, five types of oil and gas pool-forming models are built, including weathering crust, internal cavern of reversal fault block and unconformity structure reservoirs for high-location buried hills and reversal fault block and normal fault block for low-location buried hills. The theory of this paper is significant to Jiyang depression exploration and the perfection of buried hill diversity theory, and furthermore, it is a foundation for buried hill exploration under the direction of oil and gas pool-forming rules.
