采用平衡剖面技术,对饶阳凹陷中的潜山进行构造演化恢复,根据潜山形成、埋藏、定型的时期,从潜山演化历史角度,将饶阳凹陷中的潜山分为五种演化类型:早形成、晚埋藏、晚定型(早-晚-晚型),早形成、晚埋藏、早定型(早-晚-早型),早形成、早埋藏、晚定型(早-早-晓型),早形成、早埋藏、早定型(早-早-早型),晚形成、早埋藏、晚定型(晚-早-晚型).通过分析潜山的形成期、埋藏时间的长短和定型时间的早晚,认为早-晚-晚型的潜山构造(带)最有利于油气成藏.

The tectonic evolution process of buried hills in Raoyang Sag, Bohaiwan Basin, is recovered by equilibrium profile method. According to the periods of buried hill formation, burial and shaping, combined with evolution history of them, these buried hills can be divided into five types of evolution models: (1) early formation, later burial and later shaping, or Type E-L-L; (2) early formation, later burial and early shaping (Type E-L-E); (3) early formation, early burial and later shaping (Type E-E-L); (4) early formation, early burial and early shaping (Type E-L-E);and (5) later formation, early burial and later shaping (Type L-E-L). By analyzing the formation periods, the experiencing burial time, the early or later shaping, it is believed that the first Type E-L-L of buried hill (belt) is the most favourable to hydrocarbon accumulation.
