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.

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
