1.油气成因具有复合(各种各样成因)的特征,烃类的成因可以因各种途径发生:不仅按经典的沉积-运移理论方案,而且例如在岩石圈板块碰撞带中,那时油气源岩层的存在完全没有必要(俯冲-仰冲模式)。烃类流体可以直接在沉积盆地底部的沉积中在足够高热流情况下形成,并不 1. The genesis of hydrocarbons is characterized by a combination of a variety of causes, and the genesis of hydrocarbons can occur in a variety of ways: not only in the classical sedimentation-transport theory but also in the lithospheric plate collision zone, at that time The existence of oil and gas source rocks is completely unnecessary (subduction - sunning mode). Hydrocarbon fluids can be formed directly in the deposition of the bottom of the sedimentary basin with a sufficiently high heat flux and not
