查明沉积盖层构造特征是开展中、古生界碳酸盐岩新领域油气普查的关键。多年来在苏南断续进行的油气普查工作中,,进展缓慢的主要原因之一就是对沉积盖层内部构造特征搞不清。近年随着物探技术方法的改进,从江宁至丹阳的地震试验剖面(简称江丹线)取得了一些令人鼓舞的反射资料。从而对研究江苏以及我国东南部的中、古生界碳酸盐岩油气普查有一定参考意义。这里试从地震地层学方法解释分析这条剖面,以期共同讨论。
Identifying the tectonic features of the sedimentary cover is the key to the oil and gas census in the new field of Mesozoic and Paleozoic carbonates. One of the major reasons for the slow progress in oil and gas census carried out intermittently in southern Jiangsu over the years is that it is unclear about the internal structural features of the sedimentary cover. In recent years, with the improvement of geophysical techniques, some encouraging reflection data have been obtained from the seismic test section (Jiangdan Line) from Jiangning to Danyang. Therefore, it is of certain reference significance to study the general survey of carbonate rocks in Mesozoic and Paleozoic in Jiangsu and southeastern China. This section attempts to explain and analyze this section from the method of seismic stratigraphy, with a view to discussing together.
