Abstract:Usual static correction methods based on refraction wave,including the generalized reciprocal method,delay time method and ABC method,need correct firstbreak times of refraction waves and trace same high-velocity refractor. Hence,I advance a new method,relative static correction using refraction wave. The new method needs no first break times of refraction waves,but derives adjacent receiving-point relative time shifts from crosscorrelation of adjacent-trace refraction wave groups. Then the mean value obtained through mid value filtering is taken as time shift between two adjacent receiving points. Finally,we compute both the residual correction values relating to the relative floating datum and the correction values corresponding to the control-point datum.The application examples show that the new method can nicely cope with static correction in the area where surface and geological conditions are very complicated because it is characterized by good adaptability and high automation.
