渤海湾盆地辽河坳陷西部凹陷兴隆台区地质特征研究

Geological Characteristics of Xinglongtal Area in Western Depression of Liaohe Depression of Bohai Bay Basin

兴隆台潜山位于西部凹陷中部,西部凹陷属于辽河坳陷的次一级构造单元,兴隆台地区地层自下而上为太古界、中生界、下第三系沙河街组、东营组、上第三系馆陶组及第四系地层。通过对区域地层特征、构造特征和演化特征三个方面进行研究,能对辽河坳陷西部凹陷兴隆台区储层研究提供一定的指导意义。

Xinglongtai Burying Hill is located in the middle of western depression, which belongs to the sub-first tectonic unit of Liaohe depression. The strata of Xinglongtai area is Archean, Mesozoic and Lower Tertiary Shahejie Formation, Dongying Formation and the third series Guantao Formation and Quaternary strata. Based on the view of regional stratigraphic characteristics, tectonic characteristics and evolutional characteristics, we are writing this paper to provide some guidance for reservoir-study in Xinglongtai area of western depression of Liaohe Depression.
