摘　　要：古潜山油气藏是济阳坳陷内一种重要的油气藏类型.车古201潜山是济阳坳陷内较为典型的断块型潜山,深入研究其形成演化过程,不但对了解其油气成藏过程有重大的意义,而且对认识断块型潜山的成因有一定的指导作用.本次研究认为其形成演化过程可以分为4个构造期:加里东—华力西潜山雏形期,潜山呈现出低幅度背斜构造的形态,初具雏形;印支逆断期,逆断层的出现控制了潜山地层的沉积和剥蚀;燕山隆升块断期,由于埕南大断裂的生成,以及埕宁隆起的影响,虽然整个济阳坳陷处于拉张作用的背景下,但车古201潜山处于强烈隆升阶段;最后为喜山潜山定型期.由于潜山形成的多期性以及岩溶作用的影响,使车古201潜山形成了各自具有独立的油水系统,在平面上叠合连片的层状油藏.Chegu 201 buried hill is a typical fault block buried hill in Jiyang Depression. The deep study of its evolution process has not only importance of understanding oil and gas reservoir forming, but also of recognizing the genesis of fault block buried hill. According to the study of geologic background and formation characteristics, the evolution process of Chegu 201 buried hill is divided into four phases. The first phase is the forming of buried hill rudiment in Paleozic, and it takes on anticline structure during this time. The second phase is the appearance of reverse fault. The reverse fault controls the sedimentation and denudation of formation. The third phase is upthrow fault block forming period. In this time, Jiyang Depression is under the background of extension, but because of the formation of Chengnan Fault and the influence of Chengning Upthrow, the Chegu 201 buried hill is heaved strongly. In late Cenozoic, the buried hill finally forms. This is the last phase. Because Chegu 201 buried hill forms in several phases, each of its four reservoirs has itself independent oil water system. They stratifies vertically and overlaps each other on plane.
