南黄海盆地北部坳陷白垩系沉积特征
|
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39675km2,最大残留厚度为5200m,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。
A comparison research on the latest drilling and seismic data indicates that the Cretaceous sedimentary characteristics of the Northern depression in the South Yellow Sea basin are characterized by a gradual enlargement of the depression from early to middle Cretaceous and a progressing shrinkage during Early Cretaceous. This shows that the water level in the Northern depression of the South Yellow Sea basin during the Cretaceous period experienced a rise and fall process. And the cretaceous lake deposit is widely distributed. The remained Cretaceous deposit in the whole region is 39 675 km~2 in area, with a maximum thickness 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.
