不整合是一种地层现象,又是一种构造现象。石油勘探经验证明研究盆内和盆缘的不整合对认识含油盆地的发展,对生、储、盖、运、圈、保等各方面成油要素均具有十分重要的意义,它既是重要的地质理论问题,又与石油勘探有紧密的联系。无论在世界上和在中国都有愈来愈多的不整合形成的和不整合有关的油气圈闭发现。目前对于含油盆地中不整合研究的手段日益增多,形成了利用各种资料的具综合性的研究方法。研究含油盆地的不整合虽涉及方面很多,但首先遇到的就是不整合的分类和分布问题。本文仅就这两方面进行一些初步 Unconformity is a stratigraphic phenomenon, but also a structural phenomenon. The petroleum exploration experience proves that it is of great importance to study the unconformity between the basin and basin margin in understanding the development of the oil-bearing basins, oil formation elements in the aspects of genesis, storage, cover, transport, circle and insurance. It is an important geological Theoretical problems, but also with the oil exploration are closely linked. There is more and more unconformity-related unconformity-related hydrocarbon trap discovery both in the world and in China. At present, the means of unconformity research in oil-bearing basins is increasing day by day, forming a comprehensive research method using various data. Research on the unconformity of oil-bearing basins involves many aspects, but the first one we encounter is the classification and distribution of unconformities. This article only some preliminary two aspects
