地壳的新的地球物理模型与石油的无机成因说
NEW MODEL FOR THE CRUST AND INORGANIC ORIGIN THEORY OF PETROLEUM
【摘要】 根据深地震测深法、大爆破、天然地震转换波法、区域性对比折射法、共深度点法,结合重、磁、电法等地球物理方法,建立了含油气盆地的“缺花岗岩”型的地壳模型,这种模型利于地质条件下费托合成无机油气;近期提出的深部—浅部“立交桥模型”更为这种油气生成、运移成藏提供了可能;而沥青、干酪根的Pb、Sr、Nd同位素数据则为原油的无机成因揭示了十分可靠的证据,原油中Si-C键有机化合物的发现更为这种形成机理提供了一个重要的佐证
【Abstract】 Based on new geophysical data, the new crust model is prcsented. The model is characterised as ’non-granite type’ under the bottom of the basin, which favord petroleum generation by Fischer-Tropsch synthesis. The overlapping of deeper and shallower structures 1ocated the positions of petroleum reservoirs and mineral deposits. Pb-Sr-Nd isotopic systematics of kerogen and bitumen, and the discovery of Si-C bond organic compounds in the crude oils are important evidences for the inorganic origin theory of petroleum.
【Key words】 Non-granite type basin; Fischer-Tropsch synthesis; Pb-Sr-Nd isotopic systematics; Inorganic origin of crude oil;
