The basic conditions of different structure gas accumulation in the north Kuche Depression suggest that the gas supply, reservoir conditions, cap quality, trap qualification and super pressure were not dominant factors of gas accumulation. The periods of hydrocarbon generation and release, period of faults action and trap shaping phase for different structures indicated that all traps had chances to capture oil or gas. Whether gas was accumulated or not during the periods, the key conditions could be gas migration, placement and mothballing. And complication of gas resource faults which not cut through the regional cap-rock is the key factor in the north Kuche Depression.
