摘要
The surface as well as the near surface lithology in Qilian Mountains area varies roughly. Seismic source in this kind of area often generates low signal to noise ratio data. In this paper, the authors propose the following applicable measures to improve seismic source: 1) optimizing shot location in the horizontal direction; 2) shooting under the strong wave impedance interface, which can effectively reduce interference and enhance the effective energy; and 3) small charges can reduce linear noise and secondary noise. The field practices show that these measures applied in complex Qilian Mountains area improve greatly the seismic data quality.
