Abstract: Aiming at non-obvious results achieved by seismic survey in complex mountainous area in Qaidam Basin for many years, in complicate mountainous seismic survey of Qaidam Basin, it suggests changing seismic strategic ideas to adopt a series of practical geophysical new methods, new technology and new method, such as adopting 3D design concept, using the method of wide line acquiristion, selecting operation tool flexibly, fined surface survey technology, high-velocity layer tracing lithology shooting technology, the technology of selecting line and point suiting local conditions, deep hole drilling technology in complicated area, imbedding geophone receiving technology, static correcting technology, the fundamental work are strengthened, the field operation are strict to launch, the ratio of signal and noise of single shot are greatly improved, the qualities of profiles are improved, and saw the good strategic results
