Favorable Lower Paleozoic exploration targets in the Lower Yangtze region
-
摘要:
下扬子区下古生界具有良好的油气地质条件，具备形成大型油气藏的物质基础，但一直未获得油气勘探的突破。本文通过地质、地球物理综合解释，结合部分地质露头、钻井资料及上扬子勘探成果，重点对下扬子区下古生界构造地质特征与油气地质条件等开展了综合分析研究。从构造沉积充填角度将下扬子区分为4个二级构造单元，中部地区的无锡-黄山断隆带构造相对稳定，分析认为其西北部的无锡-黄桥低褶带为油气勘探的有利区带，具有形成下古生界弱改造型油气藏的勘探前景。
Abstract:Favorable petroleum geological conditions are found existed in the Lower Paleozoic of the Lower Yangtze basin. Large oil-gas accumulations are expected. However, no breakthrough has been gained so far in oil and gas exploration in this region. In this paper, based on the integrated geological and geophysical interpretation, combined with some geological outcrop data and drilling data and taking the Upper Yangtze region as a reference, we made a comprehensive analysis of the Lower Yangtze basin, which includes the studies of tectonics and hydrocarbon geological conditions. The Lower Yangtze Basin is divided into four sub-units from sedimentary and structural point of view. Comprehensive evaluation suggests that the Wuxi-Huangqiao low fold belt, which is weakly deformed, is expected a favorable target for future exploration.
