摘要：
The origin of oil and gas affects not only the configuration of energy structure in our country even the whole world but also the position and orientation of energy in social and economic development.Since the 17th century,the debate on the organic and inorganic origins of oil has lasted about 300～400 years.Although the organic origin has been a dominant theory over the inorganic origin,the latter is flourishing constantly.Based on scholars' understanding and study over the past few hundred years,in theory,both of them have their own material basis and arguments.However,it is too early or inappropriate to deny the thesis and argument of inorganic origin of oil and gas on the basis of some facts.For instance,the trace metal elements accumulate and dissipate in the source-reservoir environments of some specific oil fields throughout the world,the porphyrin molecular cannot be found as biomarkers in some oil fields,the hydrocarbon-oxidation chemical synthesis of oil achieve some development and so forth.Obviously,it is possible for the inorganic oil to migrate and permeate into the reservoirs of oil fields under the condition that the organic oil is a dominant body.Based on the above analysis,study and exploration,we propose a new idea,i.e.the hybrid origin of oil and gas (a organic origin + b inorganic origin).We sincerely hope that this new idea can be studied and explored throughout the development of oil industry in theory,technology,experiments and practice,which will be beneficial to understanding and expanding the reservoir space of oil and gas.%石油与天然气的成因问题关系到我国乃至世界各国能源结构的配置及其能源在社会与经济发展中的地位和导向.自从17世纪展开对石油的有机与无机成因的争论以来,至今已有约300～400年的历史.尽管有机成因论占据了统治地位,但是无机成因论亦不断地在兴起!通过对这二者的理解和研究,从理论上讲他们都具有一定的物质基础和论据.基于对国内、外一些特异油田的生储环境,原油中所富含的微量金属元素的聚集与散失,某些油田中并未找到卟啉分子这样的生物标志物,碳、氢、氧化学合成实验等方面取得了一定的成效,故全盘否定无机生油的论点和论据确尚感为时过早或欠妥!显然,在以有机物成油为主体的前提下,无机物亦可生成部分石油,并通过运移、渗透到各油田的储集层中应是完全可能的.基于这样的分析、研究和探索,现提出石油的双机(a有机+b无机)混合成因的新理念.诚希能在今后的石油工业发展中,从理论、技术、实验和实践中强化对双机混合成因新理念的深化研究与探索,以达深切理解和扩展石油生、储空间环境等是不无裨益的!
