METHOD OF IMAGING SUBSURFACE STRUCTURE BY REFLECTION METHOD SEISMIC EXPLORATION

摘要

PROBLEM TO BE SOLVED: To easily and accurately carry out subsurface structure imaging while reducing labor and cost for carrying out reflection method seismic exploration.;SOLUTION: A method of imaging a subsurface structure by the reflection method seismic exploration for composing visual data of a subsurface structure 1 in a measuring area comprises measuring a subsurface reflection wave reflected at a subsurface reflection point by vibration toward a subsurface generated at a time zero with a plurality of vibration receivers 5a arranged on a surface, and integrating measured data by applying prescribed processing on reflection records of the subsurface reflection wave at a surface vibration receiving point included in each measured datum with an observation part 4 provided with a data processing means. The method composes the reflection records of the subsurface reflection wave at the surface vibration receiving point by applying correlative processing by a prescribed correlative function on the measured data acquired to continuously measure subsurface noise due to random vibration without knowing the occurrence time in any one of ground surface or the subsurface with the plurality of the vibration receivers 5a.;COPYRIGHT: (C)2007,JPO&INPIT
