【摘要】 组成地球的原始物质，在原始低温条件下凝聚时就含有丰富的Ｈ＿２、ＣＨ＿４、Ｃ＿２Ｈ＿６等烃类物质和碳化物。它们被吸收和封闭于地核、地幔和地壳中。板块构造旋回所形成的各种断裂系统，以及在地球演化的各个阶段，外来天体对地球的撞击在地球上形成的裂隙系统，为地球深部无机成因的烃类物质由高温、高压环境向低温、低压环境运移提供了通道。原始的简单烃类物质在运移过程中发生复杂的聚合、化学反应，形成各种高分子碳氢化合物，而由各种基性岩和超基世岩在高温高压下脱出的大量水分在运移过程中遇到金属碳化物时，也能形成碳氢化合物。在这些碳氢化合物沿着各种断裂－裂隙系统运移途中，遇到良好的圈闭和封闭条件，便可形成各种类型的油气田（藏）。根据各种类型的板块活动带所具备的地质－地球化学条件，可划分出五种油气无机成因模式，七种油气无机成因模式组合。更多还原

【Abstract】 Fundamental materials comprising the earth contain abundant hydrocarbonsand carbonide（e.g. H₂ ,CH₄,C₂H₆） when they condensed at initial low temperature,whichthen were absorbed and trapped within core,mantle,and crust.Various types of plate tec-tonic belts resulting from plate tectonic cycle formed super lithosphere faulting system,litho-sphere faulting system,super crust faulting system,crust faulting system, basement faultingsystem,and caprock faulting system. Moreover,collision of celestial bodies with the earth canproduce size-varying fracture systems in the earth at different stages of the earth’s evolution. These systems then act as a passageway for migration of deep hydrocarbons of inorganic ori-gin from high-temperature,hish-pressure zones into low-temperature,low-pressure zones.Complex polymerization and chemical reaction of these simple hydrocarbons in the process ofmigration can generate various heavy-molecular-weight hydrocarbon。On the other hand,large amounts of water released from basic rocks and super basic rocks at high temperatureand pressure can react with carbonide to form hydrocarbon。 When good traps and seals wereencountered,these resulting hydrocarbons could be gathered into the reservoir of differenttypes。 Based on the geologic and geochemical conditions of different plate tectonic belts,inor-ganic origin model can be classified into five categories,i.e. cosmogenic gas,cosmogenic oil,crust-mantle degassification, plate tectonic belt,and deep crust-mantle, Furthermore, platetectonic cycles match well with the geologic and geochemical conditions of belts of inorganichydrocarbon origin,then seven kinds of combinations of inorganic models can also be formed.This theory will extend oil and gas exploration objectives to the Proterozoic,Archaeozoic,anddeep orogenic belt,assumed on hydrocarbon potential in organic theory,as well as deep for-mation below the so-called “deal line of natural gas”。更多还原
