盐构造研究进展述评

An Overview on Salt Structures

由于盐构造与油气的密切关系,盐构造研究目前已成为含油气盆地构造地质分析的重要内容。在过去的几十年中,盐构造研究已取得了很大进展,并促进了盐构造相关油气藏的勘探突破。本文在综合分析近年来有关盐构造研究文献的基础上,主要从盐构造发育地质背景、岩盐流变学性质、盐构造变形样式、盐构造平衡剖面复原、盐构造物理模拟和数值模拟、盐构造形成机制,以及盐构造对油气成藏控制作用等方面介绍了国外盐构造研究取得的主要成果和进展,并对我国的盐构造研究历史和现状进行了简要评述。最后指出了目前盐构造研究中还存在的一些不足,同时还对将来研究的重点做出了预测。

Due to their strategic significance on hydrocarbon accumulation, salt structures have become the focus attention in structural analysis of the petroliferous basins. During the past decades, great advances have been madein understanding salt structures, which has also accelerated exploration breakthrough of salt-related hydrocarbon pools. Based on the numerous references, this paper aims to give an overview of the research advances on salt structures from seven key aspects, which involve the geological settings, rheological properties, structural styles balanced cross sections, physical and numerical modeling, formation mechanisms and influence on hydrocarbon ac cumulations. In addition, the history and present situation of the study on salt structures in China have also been briefly introduced. In the end, this paper addresses some questions which have not been fully understood, and re search highlights in the following decades in salt structures.
