The research result of seismic gas exploration in east Chaidamu basin leads to a common conclusion, interval velocity drop {Delta}{nu} higher than 300m/s a productive gas reservoir, and {Delta}{nu} above 400m/s a high-productive gas reservoir; that is to say, the bigger the interval velocity drop is, the richer the gas in a formation is. However, the author of this paper thinks that the conclusion is unlikely to be reliable because {Delta}{nu} is not directly proportional to gas content in a formation, and present techniques fail to determine accurate {Delta}{nu}.
