Abstract：There is abundant gas resource in Quatarnary in east of Qaidam Basin.Because of the complexity of shallow seismic-geologic condition and speciality of gas-bearing anomlay,both the gas-bearing anomaly and the change of shallow geologic condition can cause such seismic anomaly as"low frequency,low velocity,poor signal-to-noise ratio and pulling event down",which bring a lot of difficulties in seismic exploration of gas-besring area and in explanation of the phenomena.On the basis of theoretical analysis,the high-resolution seismic exploration in east of Qaidamu Basin adopted the acquisition techniques such as short group interval,short geophone distance,shallow shot-hole depth,short offset,dense sample interval,high multiplicity,shooting in multiple shot-holes,receiving in array of multiple geophone,highlighting the low-frequency information having in gas area and highlighting target of exploration and according to the characters of work area,the data processing adopted such techniques as noise suppression,deconvolution and stack by frequency division that place emphasis on gas-bearing anomaly ares,which sum up a suit of high-resolution techniques suitable for the exploration of gas-bearing zone in that basin.
