The discovery of gas hydrates provides a wide sphere and a new way of thinking for finding clean and effective energy resources to replace increasingly exhausted traditional energy resources. Moreover, in our country there are a wide realm and bright prospect in the exploration of gas hydrate. This paper has summarized the progress on the study of gas hydrate. And based on the former research about gas hydrates, the integrative identification signs of gas hydrates were summarized in the aspects of seismic data, geophysical well logging, sedimentary and rock, geochemistry, topography and morphology. In the end, the author hopes it may provide some useful clues to the exploration of gas hydrate Keywords: integrative identification signs; gas hydrate; exploration Introduction The initial evidence of gas hydrate occurrence is the saturated gas hydrates coring from the exploration bore in 1967, although it was found foremost in 1778. Under conditions of STDATM, one stere
