特提斯壳体演化新解与青藏高原含油性分析
|
摘要
近30年来,运用板块构造研究特提斯海的形成演化,获得了许多难以解释的资料.新的研究认为,颤动构造(su孵te(:conics)是特提斯海演化的驱动力.亚东一安多岩石圈内存在上下两个颤动通道,南部上地幔隆起.由于构造作用,始新世从通道内沿雅鲁藏布江向上向外涌出融熔岩浆,形成蛇绿岩和混杂体.地震和地热也沿该断裂带分布.同样,在此之前形成了班公湖一怒江和西金乌兰～金沙江颤动通道及其断裂带.中新世,3个颤动通道横向扩展,相互联成一片,然后青藏高原开始整体隆升.随着颤动通道的形成演化,形成了数十个沉积盆地,发育有多套生储盖组合.以坳陷型盆地海相沉积岩系所含油气较好,目前已钻探发现工业性油流.
During the past 30 years in the study of the formation and evolution of the Tethys Sea by the theory of plate tectonics,a large volume of information which cannot be explained by the plate tectonic hypothesis has been accumulated.It is believed that surge tectonics is the driving force for the evo- lution of the Tethys Sea.Two surge channels,an.upper and a lower,exist in the Yadong-Anduo lithosphere,and the upper mantle in the southern part is uplifted.During the Eocene,tectogenesis ted mol- ten magma to pour out from the channel along the Yarlungzangbo River,forming ophiolites and melanges,and earthquakes and terrestrial heat to distribute along the fracture zone.Likewise,at an earlier time it formed the Banggong Co-Nujiang and Xijinwulan-Jinshajiang surge channels and their fracture zones.During the Miocene,the three surge channels merged laterally,and then the unified rise of the Qinghai-Xizang Plateau took place.The formation and evolution of the surge channels resulted in a series of sedimentary basins.These basins contain multiple sourcebeds,reservoirs,traps and seals.At pres- ent commercial oil flow has been penetrated by drilling.
