Abstract: There are some problems in unconventional hydrocarbon enrichment research,such as unclear key controlling factors,unclear enrichment mechanism and efficiency. By means of investigation,field observation, core description,microscopic identification,simulation experiment and statistical analysis,combined with its own research outcome,this paper proposed the hypothesis of "fracture-pore coupling enriching hydrocarbon" based on the knowledge of fracture-pore coupling is the key controlling factor restricting unconventional oil and gas retention,migration,accumulation and enrichment. The main conclusions are as follows:(1)Fracture-pore coupling not only controls the dynamic and resistance of unconventional hydrocarbon migration,accumulation and enrichment,but also controls their migration channels and accumulation space,as well as their phase, mode,fluid flow rule and efficiency of migration and accumulation.(2)There are 16 kinds of fracture-pore coupling and four evaluation levels of fracture-pore coupling of advantage coupling,good coupling,general coupling and unfavorable coupling,and fracture-pore system with advantage coupling is most conducive to the migration,accumulation and enrichment of unconventional oil and gas,followed by that with good coupling.(3)This paper summarized the background,basic principle,main basis,main viewpoints of the "fracture-pore coupling enriching hydrocarbon hypothesis", and exploration strategy based on this hypothesis. This hypothesis has important guiding significance for unconventional oil and gas exploration,but it still needs further revision,improvement and development to develop the unconventional oil and gas accumulation theory.

Key words: unconventional oil and gas, fracture-pore coupling, advantage coupling, hypothesis of enriching hydrocarbon
