摘要:
提要:塔里木盆地东河砂岩是中国首例海相深层含油气沉积储层。笔者通过对塔里木盆地地质和地球物理资料综合研究发现,塔中和塔北东河砂岩均具有较高的成分和结构成熟度、典型的海相粒度参数和微量元素组合、明显的滨浅海沉积构造等特征,但在沉积特征细节和沉积环境等方面还存在着差异。塔北地区东河砂岩段沉积于滨岸及障壁岛—泻湖环境,塔中地区东河砂岩段沉积于河口湾—滨岸环境。进而阐明了塔中和塔北东河砂岩段沉积特征的垂向序列和沉积相平面分布特征。

Abstract:
Abstract:The Donghe sandstone is a marine petroleum-bearing reservoir that was first found in China. An integrated study of the geological and geophysical data of the Tarim basin show that the Donghe sandstone in Tabei and Tazhong has high compositional and textural maturities, typical grain-size parameters of the marine environment and trace element association and distinct littoral-neritic sedimentary structures. However, there are differences in details of sedimentary characteristics and sedimentary environment in the Donghe sandstone. The Donghe sandstone in the Tabei area was deposited in the littoral and barrier island-lagoonal environment, while the sandstone in the Tazhong area in the estuary-littoral environment. Finally, this paper elucidates the vertical sequence of the sedimentary characteristics and distribution of sedimentary facies of the Donghe sandstone section in the Tabei and Tazhong areas.
