Multifunctional broad-band seismic assemblage SEP-1

Abstract

Results of research and development of three velocimeter components in the form of an assemblage of mechanical seismic detector and boards of electronics, realizing stabilization of inertial mass zero point and formation of amplitude-frequency characteristic, are presented. Original electromagnetic system of mass suspension for the vertical variant is applied in the seismic detector; it gives a possibility of mass reduction to the variant of horizontal seismic detector without change of the general design. The suspension system consists of two cylindrical magnets and a ferromagnetic shunt. On the basis of the developed seismic detectors, design of the multifunctional seismic assemblage SEP-1 is realized allowing its application for solution of a wide variety of seismologic problems at measurements both in base variant and in wellholes.
