Improvement on spectrum equilibrium filter in seismic data acquisition system

YUAN Zi\|long, CAO Guang\|hua ( Dept of Petroleum Prospecting, Daqing Petroleum Institute, Anda, Heilongjiang151400 ,China )  
The main factor that affects the resolution of seismic prospecting is Earth's absorption and attenuation effect on high frequency signals. Study and calculation of Earth's absorption and attenuation effect show that medium deep and deep reflectors over 135 Hz can not be recorded even by 24-bit seismometers. To effectively compensate the Earth's absorption and attenuation effect on high frequency signals, a new kind of time variable SEF has been designed which can switch its parameter of resistor network according to time. This makes it possible to compensate high frequency components of shallow, medium and deep reflections with proper ratio, thus can improve the resolution of seismic prospecting.
