| 摘 要： | 通过钻井和地震最新资料的对比研究表明,南黄海盆地北部坳陷白垩系的沉积特征沉积范围由下白垩世到中白垩世逐渐扩大,再到上白垩世又逐渐缩小.这说明南黄海盆地北部坳陷白垩纪经历了一次水进和水退的过程,并且南黄海盆地北部坳陷白垩纪普遍发育湖泊相沉积.白垩系在全区的残留面积为39 675 km2,最大残留厚度为5 200 m,有利于有机质的生成和转化,预示了白垩系较好的生油能力.

| Abstract: | A comparison sedimentary characteristics o by a gradual enlargement of during Early Cretaceous. T Yellow Sea basin during the lake deposit is widely distrib area, with a maximum thick research on the latest drilling and seismic data indicates that the Cretaceous f the Northern depression in the South Yellow Sea basin are characterized the depression from early to middle Cretaceous and a progressing shrinkage his shows that the water level in the Northern depression of the South Cretaceous period experienced a rise and fall process. And the cretaceous uted. The remained Cretaceous deposit in the whole region is 39 675 km^2 in ness of 5 200 m, hence presenting good conditions for the generation and transformation of organic matter and indicating a better oil and gas potential in this region. |
