Geological characteristics of the Meso-Paleozoic in South Yellow Sea Basin and future exploration
-
摘要:
南黄海广泛发育海相中、古生界,资源量丰富,勘探潜力大,但一直未取得勘探突破。通过与上扬子四川盆地类比,最大的差异在于后期构造改造的强度不同。南黄海盆地遭受多期次强烈的后期改造,致使早期生成的油气被破坏和改造,不利于油气保存,在南黄海区内寻找构造相对稳定的区带,是南黄海盆地中、古生界取得油气突破的关键;综合南黄海残留地层分布、石油地质条件、构造变形特征等的研究结果,对南黄海中、古生界最具现实勘探意义的区域进行了优选,认为崂山隆起中南部弱变形区是南黄海中、古生界实现勘探突破最有利区带,下古生界是下一步重点的勘探层系。
Abstract:The South Yellow Sea Basin is a large Mesozoic-Paleozoic petroliferous basin with substantial hydrocarbon potential. However, there has had no breakthrough so far in oil exploration in the basin. Comparison suggests that the biggest difference between the South Yellow Sea Basin and the Sichun Basin is mainly caused by tectonic intensity. It is known that the South Yellow Sea Basin has suffered from multi stages of tectonic movement in the periods of Mesozoic and Palaeozoic and the preservation conditions are damaged to certain extent. Breakthrough in oil and gas exploration is expected in some tectonically stable zones. Based on the above observation, this paper is devoted to the tectonic- sedimentary evolution as well as the stratigraphic distribution of South Yellow Sea Basin, following the evaluation of petroleum geological conditions. Some target areas with weak deformation in middle-south area of Laoshan uplift are identified and the lower Paleozoic is selected as the key exploration strata. Some target areas such as the middle and south Laoshan uplift where deformation is relatively weak are recommended for future exploration.
