【摘要】 油气的有机成因论和无机成因论都有各自的立论依据,但都存在一些不能圆满解释的现象,应用热液矿床水相变控藏(矿)理论来分析油气成因,可能能够给出较好的解释,至少可以提供一些新的思路。水相变控油气论认为油气生成和运移是与水混合在一起进行的,可把油气当作一种特殊的热液矿产;当地壳局部区域为封闭体系时,按上地壳地温线,油、气、水组成的热液为液相,而当遇到断裂或褶皱等造成局部降压后,含油气水的热液体系就会发生水与油气的相变分离,从而形成油气藏。由此分析了油气成因中与热液成矿作用相关的现象,并用岩石圈中水的相变规律,初步解释了油气、低速高导层、热液金属矿床、地球排气和地震等成因的统一性。更多还原

【Abstract】 Both the organic genesis theory and inorganic genesis theory on the formation of oil and gas have their own evidences,but any one always has some phenomena not to be satisfactorily explained.In the study of the genesis of oil and gas,the theory of water phase transition controlling hydrothermal mineralization may give a better explanation,or at least provide some new ideas.According to the theory of water phase transitions controlling the formation of oil and gas,the generation and migration of oil and gas are always mixed with water together,even the hydrocarbon is as a special hydrothermal mineral.Under a closed system in the crust,according to the upper crust hydrothermal geothermal lines,the fluid mixed hydrocarbon with water is the liquid phase.But when pressure reduction caused by the fault or fold,the fluid system will take place the separation of water and hydrocarbon,and result in the formation of oil and gas reservoirs.Bases the theory,this paper analyzed the phenomena related with hydrothermal mineralization in the formation of oil and gas.With the laws of water phase transitions in the lithosphere,this paper also explained briefly the geneses oneness of the formation of oil and gas,hydrothermal metal ore-deposit,the low velocity-high conductivity layer,the earth degassing and the earthquakes.更多还原
