Abstract

The invention discloses a spring piece for seismic detection, a detector and a seismic exploration system. The spring piece for seismic detection comprises an outer ring (1), an inner ring (2) and a plurality of connecting arms (3). Specifically, one end of each of the connecting arms (3) is connected to the inner edge of the outer ring (1), the other end of each of the connecting arms (3) is connected to the outer edge of the inner ring (2), and the width of the connecting arms (3) close to a connecting position of the outer ring (1) and / or the inner ring (2) is smaller than that of the middle positions of the connecting arms (3). Compared with a traditional spring piece, the spring piece has smaller shape change under the condition of a same stress, so that nonlinear distortion of a detector and a seismic exploration system provided with the spring piece is reduced, and then seismic detection is more accurate.

Description

technical field [0001] The invention relates to the technical field of seismic detection, in particular to a spring sheet, a geophone and a seismic detection system for seismic detection. Background technique [0002] The geophone is located at the forefront of the seismic acquisition system and is used to receive seismic signals. It is the key core device for field seismic data acquisition. The moving coil geophone has the advantages of economy, durability, and stable performance, which makes it widely used in the field of seismic exploration. For more than 70 years, it is the main force in the current seismic exploration geophone. [0003] Seismic inversion is based on the premise that the geophone is a linear system. Whether it is the shallow fine engineering exploration field or the deep high-quality oil and gas resource exploration, a high-linearity geophone is required. The non-linearity of the geophone Mainly due to the nonlinearity of its internal magnetic field and...
