摘要
Abstract
In western Chinas loess area,the static correction problem is very prominent. Fine,accurate near-surface structure survey is very important for solving the problems of excitation well depth design and static correction. However,on the one hand,the terrain is very complex,resulting in extremely low conventional rolling refraction interpretation accuracy; On the other hand,its very difficult to trace the high-speed layer through the micro logging because of the thick loess coverage. Therefore,the problem as to how to take good shot records and how to do well in the static correction processing has become a major difficulty in seismic exploration of these regions. The authors proposed a new method for near-surface structure survey on the basis of full test,i. e. ,the chromatography method,which can effectively solve the difficulty. A comparison with the conventional refraction method shows that this method can obtain richer information and depict more finely the near-surface structure. Therefore,it can be used fairly well in such aspects as the well depth design and the establishment of the initial model for static correction processing.关键词
