发布时间：2019-05-22 17:18
【摘要】：烃源岩生成演化是一个长时间的复杂过程,无机组分在此过程中起到重要作用。研究后可知,水、矿物、过渡族元素及放射性元素等可以作为反应物或催化剂,对油气形成和演化的全过程都有影响;铀、钍、钾等放射性元素除了具有催化作用以外,其放射性辐射作用可使微生物在生存繁殖过程中快速勃发,为油气的生成提供超过正常生存环境的有机物质;细粒黏土矿物、各类氧化物氢氧化物等由于其吸附性,是决定地层中有机质含量及其生烃潜力的重要条件之一。其他无机元素,如锗、镓等均存在与有机矿产共存的现象。研究后认为,在油气形成过程中,有机、无机相互作用普遍存在,并且扮演着重要的角色。
[Abstract]:The formation and evolution of source rocks is a complex process for a long time, in which inorganic components play an important role. It can be seen that water, minerals, transition elements and radioactive elements can be used as reactants or catalysts to affect the whole process of oil and gas formation and evolution. In addition to catalysis, radioactive elements such as uranium, thorium and potassium can make microorganisms develop rapidly in the process of survival and reproduction, and provide organic substances beyond the normal living environment for the formation of oil and gas. Fine clay minerals and various oxide hydroxide are one of the important conditions to determine the content of organic matter in formation and its hydrocarbon generation potential because of its adsorption. Other inorganic elements, such as germanium and gallium, coexist with organic minerals. After the study, it is considered that the interaction between organic and inorganic exists widely in the process of oil and gas formation, and plays an important role.
