The carbonate reservoir in the Central Tarim Basin is one of the main targets of hydrocarbon exploration. The appropriate technical measures of seismic acquisition were proposed. Firstly, the authors investigated the absorption and attenuation of seismic wave in loose sand-dune, and implemented the experimentation of receiving in high-velocity layer. The result indicates that absorption and attenuation on the seismic wave with the main frequency below 35 Hz in sand-dune isn’t serious, and geophone array is one important method for improving signal-to-noise of seismic data. Secondly, the authors studied 3D geometry design method for fracture-cave reservoir of carbonate, which presents the design method of trace density and the design principle of 3D geometry for assuring bin attributes uniformity. Finally, by the analysis of the elevation difference of geophone array, a flexible design method based on the properties of sand dune was proposed. The methods were used to the 3D seismic exploration in the Central Tarim Basin, and good result was obtained.
