【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更多还原

【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.更多还原
