摘 要: | 近年来,底辟型油气构造圈闭在我国东部各含油气盆地的研究中,已开始引起重视。盐丘构造的存在,一般已不再有很大争论。但是,对底辟构造存在的广泛性,特别是对底辟作用在我国东部中、新生代含油气盆地的构造演化中,究竟有多大影响,我国底辟型构造圈闭的形态、结构以及形成机制上有什么特点,对油气聚集的控制有那些规律可循等等问题,为文论证者还不多见。

A PRELIMINARY STUDY ON DIAPIRIC STRUCTURE IN OIL AND GAS—BEARING BASINS IN EASTERN CHINA |
| |
Abstract: | In the tectonic evolution of Meso-Cenozoic oil and gas-bearing basins in Eastern China,the diapirism,by which oil and gas structural traps are formed,are quite obvious.This paper will focus on the mechanism of salt and mud diapiric structural traps intruded at low temperature.In the meantime we will preliminarily probe the possibility of the existence of magmatic diapiric structures which are intruded at high temperature.It is emphasized that the distribution of soft mudstone are obviously much wider than that of salt and gypsum in the eastern basins of China,therefore,the diapirism of mudstone should be paid more attention to. |
