“石油无机成因说”的理论与实践

Theory and practice of petroleum inorganic origin

对石油的无机成因理论进行了评述,其中包括地幔脱气论、中地壳与费-托合成说、板块构造与费-托合成说.沥青、原油、干酪根的Pb-Sr-Nd同位素,原油及沥青中高含量的微量元素以及原油中的有机化合物均揭示了原油无机生成的科学依据,这是中国科学家对石油地质学的重大贡献.石油的无机成因理论是可以指导油气勘探的,并以辽宁义县-北票地区、苏南地区、鄂尔多斯盆地伊盟隆起、四川松潘-甘孜褶皱带、柴达木盆地为例讨论了寻找大油气田的可能性.

Inorganic origin theory of petroleum is discussed and reviewed.The mantle degassing,Fischer-Tropsch synthesis reactions in the mid-crust and in the plate tectonics environment are especially discussed.Based on the author's research,Pb,Sr,Nd isotopic data in the bitumen,crude oil and kerogen,high content of trace metal elements in crude oil and bitumen,and metallorganic compounds in crude oil all are evidences supporting the inorganic origin of petroleum,which is the great contribution of Chinese scientist to petroleum geology in the world.The inorganic origin theory of petroleum can guide the petroleum exploration practices.The possibility finding large oil-gas fields in Yixian-Beipiao region of Liaoning Province,Southern Jiangsu,Yimeng uplift of Ordos Basin,Songpan-Ganzi fold zone of Sichuan Province and Qaidam Basin is discussed.
