Single-point high-sensitivity detector

Abstract

The invention relates to a single-point high-sensitivity detector, which solves the technical problems that due to the low sensitivity, an existing detector can be effectively used after various combinations in field application, and the combined detector has the characteristics of large amount, heavy weight and large construction strength and is difficult to realize high-density field acquisition. The single-point high-sensitivity detector comprises a steel magnet, magnetic boots, magnetic-conductive casings, coil frameworks, coils, spring leaves, upper covers, lower covers and leading-out terminals, wherein the magnetic boots are arranged at upper and lower ends of the steel magnet; the magnetic-conductive casings are arranged at outer parts of the magnetic boots; coil systems are arranged in the gaps between the magnetic boots and the magnetic-conductive casings; the spring leaves are arranged at end parts of the coil systems; the coil systems are connected with the magnetic boots through the spring leaves; and the upper covers and the lower covers are arranged on the peripheries of the magnetic boots and respectively fixed at upper parts and lower parts of the magnetic-conductive casings. The single-point high-sensitivity detector can be widely applied to detectors.

Description

technical field [0001] The invention relates to a wave detector, in particular to a single-point high-sensitivity wave detector. Background technique [0002] We know that the current geophones used in petroleum exploration are mainly magnetoelectric geophones, and the magnetoelectric geophones widely used now mainly have three specifications: PS-10ES, PS-10X and PS-10GS. The sensitivities are 28.8v / m / s, 19.7v / m / s, and 22.8v / m / s respectively. When used in the field, it is generally used to combine single detectors, such as 3 in series, 6 in series, 6 The main purpose is to improve the sensitivity of the detector to realize the effective collection of on-site vibration signals. [0003] With the continuous development of oil exploration technology in the direction of high density and high sensitivity, the requirements for geophones are getting higher and higher. Geophones are required to have the characteristics of high sensitivity, small size, light weight, and low construc...

AI Technical Summary

Problems solved by technology

[0004] The present invention aims to solve the problem of low sensitivity of the existing geophones, which require various combinations in field application before they can be effectively used. After combination, the number of geophones is large, the weight is heavy, and the construction intensity is high, so it is difficult to realize the technology of high-density field collection. The problem is to provide a single-point high-sensitivity geophone with high sensitivity, no need for on-site combination, small size, light weight, low construction strength, and high-density on-site acquisition.
