Abstract: S-wave seismic exploration has many natural advantages，such as micro-fracture prediction and gas cloud area imaging. In recent years，the attention and research of geophysical circles on S-wave exploration are rapidly heating up. S-wave seismic acquisition，however，is obviously different from the P-wave seismic acquisition that we are familiar with regarding excitation，reception，and other aspects，and has more restrictive factors and stricter requirements for construction quality. In this paper，the piedmont S-wave seismic acquisition test line in the Tarim Basin is used as an example to expound in detail the construction process and quality control technology of the key links such as the embedding and angle correction of the 3-component geophone，as well as the excitation azimuth control of the S-wave source. The processing and analysis results of S-wave data show that in order to improve the imaging effect of Swave seismic acquisition data，an observation system with higher coverage times and larger S-wave source driving amplitude should be adopted in terms of S-wave seismic acquisition method，high，steep and complex structural areas should be avoided where possible in terms of deep seismic geological conditions，and the control of environmental noise should be strengthened in terms of the signal-tonoise ratio of original data. Field tests have provided technical reference for the quality control，popularization and application of Swave seismic acquisition technology.
