Abstract:

There is great difference of seismic exploration between in mountain regions and in plain-water-system regions, which is mainly caused by different surface lithologies. For the seismic exploration in the plain-water-system region, besides both the test of each data acquisition and the investigation of surface lithological changes, it is the key to make out the design of observation system of seismic exploration in residential area. In order to get good effects of seismic exploration, several important aspects for this design include as follows: firstly, the seismic exploration do not damage surface buildings; secondly, it is possible to get good effects for each single-shot seismic record; thirdly, it is the best to reduce spent shot. The main methods include many following measures: strengthening the energy of seismic reflection waves by improving quality of both initiation and accepting;improving the quality of seismic profile through controlling noise and the adaptation of method of the little dose in deep well.
