哈萨克斯坦S区块盐构造类型及其成因机制
|
摘要
哈萨克斯坦S区块构造位于滨里海盆地阿斯特拉罕—阿克纠宾斯克隆起带与中央坳陷带的东部,滨里海盆地是一个典型的含盐盆地,盆地内盐岩经历了多期的构造运动,形成了丰富多样的构造类型。盆地中部阿斯特拉罕—阿克纠宾斯克隆起带和南恩巴隆起之间的区域,是一个重要的油气聚集区。以地球物理学、地质地震模型等理论为基础,针对该区盐构造类型及其成因机制进行分析,总结与盐相关的盆地地质特征,对含盐盆地发现油气具有非常重要的意义。
Block S structure in Kazakhstan was located in the east of Astrakhan-Aktyubinsk Uplift of Pre-Caspian Basin and the Central Depression Belt. Pre-Caspian Basin was a typical salt bearing basin where several periods of tectonic movement were occurred,forming varied tectonic types. In the central basin,the area between Astrakhan-Aktyubinsk Uplift and Nanenba Uplift was an important oil and gas concentration area. Based on the theories of geophysics,geological and seismic models,the author analyzed the salt structure types and their genetic mechanism in the study area,summarized the geological features of the basins related with salt which would be beneficial to the future prospecting of oil and gas in the salt bearing basins.
