Abstract
In the land seismic survey,mechanical vibration of the ground are recorded as seismic data.Normally this data is described in velocity or acceleration,two are common forms used for onshore petroleum exploration. We discuss in the paper the meaningful frequency band and amplitude range of onshore seismic survey in velocity and acceleration,and analyze various factors involved in the seismic recording system(sensor,sensorground coupling,and seismograph).In land seismic survey,commonly used sensors are geophones,among which the model 20DX geophone is very popular.Another one is MEMS,an acceleration sensor,Sercels DSUs for instance.We review velocity and acceleration of typical sensors,compare their consistency of data, and analyze recorded data reasonability and validity with physical and numeric results.Finally more geological and geophysical factors should be taken into accounts carefully when selecting the description domain of seismic data.关键词
