1 前言源于被动大陆边缘海相盆地、以地震地层学为基础的新兴地层学分支学科——层序地层学是70年代末形成的。由于该理论在指导油气勘探方面取得了重要成功,因而自80年代初一经被引入我国立即受到了国内同行的关注,特别是受到了石油部门有关科研、生产单位的高度重视,现已形成了一股势不可挡的应用研究热潮。但是,不同学者在应用该理论时由于理解上的差异、所涉及的实际问题不同、采用的标准不同,结果导致对层序地层学理论本身不可避免地存在许多有争议、亟待完善和解决的问题。本文就目前层序地层学中所存在的有关概念加以论述,与同行进行讨论,以便在今后的工作中取得比较一致的认识,从而更好地应用该理论解决有关实际问题。
1 Introduction From the passive continental marginal marine basin, the epoch stratigraphy is based on the emerging branch of stratigraphy - sequence stratigraphy was formed in the late 70s. Since this theory has made great success in guiding oil and gas exploration, it has been immediately attracted the attention of domestic counterparts since it was introduced into our country in the early 1980s. In particular, it has received great attention from relevant scientific research and production units in the petroleum sector. Now it has formed a The irresistible application research boom. However, due to differences in understanding, different scholars have different practical problems and different standards adopted by different scholars. As a result, there are many controversial and urgent problems to be solved in the theory of sequence stratigraphy . In this paper, the existing concepts of sequence stratigraphy are discussed and discussed with their counterparts in order to obtain more consistent understanding in future work so as to better apply the theory to solve practical problems.
