下扬子地台有良好的生烃和储盖条件,但由于保存条件不好一直未获得理想的勘探效果.南黄海盆地勿南沙隆起受构造运动影响较弱,盖层保存良好,构造相对完整,该区A构造有地震含气异常,其周围还发育了一批背斜,是下扬子地台油气勘探的方向. The Lower Yangtze platform has good conditions of hydrocarbon generation and accumulation but no ideal exploration results due to poor preservation conditions.Bunsha Sha uplift in South Yellow Sea Basin is less affected by tectonic movement and the cover is well preserved with relatively complete structure, There is an anomaly of anomalous earthquakes in this area A and a series of anticlines are also developed around it, which is the direction of oil and gas exploration in the Lower Yangtze platform.
