Tarim basin is located in northwestern China and is the one of main basins with abundant oil and gas. Due to existence of thick low velocity-reducing layer in desert area of the basin, it is very difficult to gain good seismic datum. The main problem in collecting data include: 1) Bad shot and receiving situation cause very low signalto- noise ratio and low resolution; 2) Undulant hypsography make complicated static correction; 3) Surface deep sand stratum induce absorption and attenuation of seismic wave. To finish the geologic target, we introduce following methods: 1) Enhancing analysis and investigation of surface structure to perfect surface structure model which will serve for choosing better shot points; 2) Exploding under water table to guarantee enough shot energy, and embed the geophone to get the better receiving condition; 3) Selecting bigger diameter of dynamite to form better point explosive response; 4) Surveying the noise wave to design the best acquisition parameters; 5) Calculating better static correction by surface refraction tomography; 6) Applying the compensation of absorbed energy of seismic wave to gain better information. After these methods are introduced, the signal-to-noise ratio and resolution of main prospecting objective in collecting seismic datum are improved obviously and obtain correct geologic interpretation.
