【Abstract】 As the forefront of seismic data reception and acquisition equipment,the performance of geophones used for detecting seismic signals directly affects the seismic data interpretation work. With the development of seismic observation technologies and the enhancement of the exploration ability,the large-scale seismic array observation will become an important means and a trend of high resolution imaging of deep structure.The seismic array adopts high resolution seismic observation systems to observe underground weak seismic signals in a wide range and a long time,and we use unique seismic data processing methods to suppress the ground noise in order to improve the signal-to-noise ratio and achieve the accurate inversion information of the earth deep structure.This article first describes the present situation of low-frequency geophones, mainly introduces broadband geophones, electrochemical geophones, new type digital geophones based on MEMS technology and an optical fiber sensor,and then briefly reviews the seismic array observation.With typical seismic array observation projects as examples,this paper also introduces the application and main achievements of low frequency geophones in seismic array observation,and finally points out the future development trend of seismic geophones.更多还原
