ANALYSIS OF THE DETECTOR INTERVAL SELECTION IN SHALLOW REFRACTION SEISMIC DATA INTERPRETATION
Chen Xin-qiu · Computing Techniques for Geophysical and Geochemical Exploration · 2010
The detector interval is an important parameter in shallow refraction seismic exploration,its reasonable choice guarantees to reliability of the interpretation results.Especially,in the refraction seismic exploration under duality or multi-cell terrain condition,it is disunity to use actinic interval or slantwise interval in different companies.In this paper,the error and effect to near surface effective velocity caused by selecting actinic interval or slantwise interval based on theory and computing are discussed,and then the issue of the error and rationality of different selection of actinic interval or slantwise interval in the refraction seismic data interpretation with duality or multi-cell terrain condition is opened out.
