Abstract

Compared with marine gas hydrate, continental gas hydrate in Muli permafrost Qilian Mountain has a discontinuous vertical distribution and bad horizontal relativity, in addition, no BSRs or other reliable marks can be used. So gas hydrate exploration methods of permafrost have obvious difference with that of ocean. According to recent exploration works in Sanlutian study area, Muli permafrost, core observation, test analysis, well logging, seismography, drilling, gas logging, geochemistry and other methods are used to summarize the gas hydrate identification characteristics. Each method has its reliability level and fineness, so comprehensive researches must be conducted to improve the exploration level.
