The Seismic Adaptability Discussion by Different Sorts of Geophone in Marine Facies of West Sichuan Province Area
Huan Xiuju, Zhang Weihong, Liu Yuanzhi, Yu Wenke, Wei Li · 2014
The oil exploring experts have been confused by the complex near-surface and sub-surface special seismic geological conditions for years, especially for the imaging precision of deep marine facies longitudinal resolution. Through 10 years of shooting conditions study and experience, the exploring effect is improved apparently. But how about the receiving conditions? Can it be also improved as well as different sorts of geophone have been developed? By comparing the principle and on-site tests of normal geophone, high frequency geophone, Magnetic levitation geophone, piezoelectric geophone and digital geophone, as a result the digital geophone can improve the frequency bandwidth a little but not too much.
