This theory is demonstrated by three examples: the natural gas blowout when drilling in the permafrost, the hydrate cropouts in the seafloor and the gas bubbles in abyssal plumes. Then, several conclusions are drawn: there maybe exist the seeping and diffusing types of gas hydrate reservoirs which may still be growing in the Xisha trough, Dongsha continental slope of the South China Sea, west and south of Taiwan basin, and Bijianan basin; whereas in the Qiangtang basin of the Qinghai\|Tibet plateau may exist the regressive\|type gas hydrate deposit. Furthermore, the phenomenon of hydrocarbon gas leaking in the Qilian mountain areas and Junger basin indicates that these areas may ensconce gas hydrate reservoirs.
