【Abstract】 The present paper briefly introduces the traditional theory on hydrocarbon geneses and the concept of "commercial deadline of exploration", outlining that the study on deep oil and gas is to break through "the theory on the hydrocarbon generation from late kerogen" and to search for deep oil and gas resources beneath the current explorative depth. Moreover, the theory on deep oil and gas as well as its key effective factors is also discussed in detail. The study on the abiogenic gas concerns searching for natural gas resources generated from abiogenic (inorganic) processes in the deep earth, the paper discusses in detail the theory on the abiogenic gas, introduces achievements obtained in this research field and reports the discovery of abiogenic gas reservoirs from the Songliao Basin and their evidence, providing a typical research example in this research field. In addition, on the basis of the above researches, a kinetic\|thermodynamic model on the organic matter evolution in the interior earth.更多还原
