成矿热液与石油生成

Mineralized Hydrothermal Liquid and Petroleum Generation

热液矿床与油气田常相伴分布，我国原油中存在有较多的含量超过中国陆壳平均含量一倍以上的成矿元素，新疆石油中有38个（占检测元素的64．41％）、辽河原油中有35个（占检测元素的77．77％）、大庆石油中有35个（占检测元素的58．33％）、大港原油中有16个（占检测元素的28．07％）。这是由于来自地球深部的成矿热液，携带有350℃以上的热能和来自地球深部的成矿元素所造成的。当成矿热液与有机质相遇并发生作用时，温度促使有机质向烃类物质转化；而其中的成矿元素又促使有机质中的碳原子与氢原子更多更快的结合，使有机质向烃类转化的过程加快而转化量又提高。由成矿热液催化生成的烃类富含成矿元素，并形成了热液矿床与油气田相邻分布的景观。

： Hydrothermal deposits are usually distributed in association with oil and gas fields． In the China＇s crude，there are many mineralized elements whose content are twice of the average content of the China＇s continental crust，with 38 in Xinjiang crudeaccounting for 64．41％ of the elements detected， 35 in Liaohe oilaccounting for 77．77％， 35 in Daqing oilaccounting for 58．33％， 16 in Dagang oilaccounting for 28．07％ respectively． This is caused energy carried in mineralized thermal liquid over 350℃ and the mineralized elements from the deep portion of the earth． When mineralized thermal liquid and the organic matter meet and react with each Other， the temperature Prompted transformation of organic matter into hydrocarbon matters while the mineralized elements enhanced combination of more carbon atoms and hydrogen atoms in the Organic matter， and accelerated the process of transformation from organic matter to hydrocarbons and enhanced transformation． The hydrocarbon compounds generated by catalysis of mineralized thermal liquids are rich in mineralized elements， which resulted in the fact that the hydrothermal deposits are adjacently distributed with oil and gas fields．
