关于石油成因理论的争鸣

A Probe of Theory of Petroleum Origin

21世纪初的几年间,关于石油成因理论的争鸣一直在进行着,国外(如美国、俄罗斯等)对于油气无机成因的研究也在进行着。面对诸如膏盐、白云石(岩)、粘土矿物等成因的石油地质学的一些基本问题也在深入展开,至于深部流体、地幔柱与油气关系的讨论也开始引起注意。重要的是,近年来,石油无机成因理论已开始应用于油气勘探实践,即预测未来油气勘探的靶区。油气无机成因的现代概念已逐渐形成。

In just a few years after the beginning of 21th century, the arguments against the organic origin theory have been kept going. The studies of inorganic petroleum origin abroad （e.g. America, Russia, etc.） have been made in progress. The in-depth analyses of some fundamental issues in petroleum geology about origins of gypsum-salt, dolomite and clay mineral, etc. have been conducted. The relationship among deep fluids, mantle plume and hydrocarbons is beginning to arouse more attentions. The more important thing is that the inorganic petroleum origin theory has been applied to the practices for oil-gas exploration at home and abroad for prediction of targets of hydrocarbon prospecting to come. It is concluded that the modem concept of inorganic petroleum origin has gradually been formed.
