Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 24260-2009 "Petroleum Seismic Detector", compared with GB/T 24260-2009, except for editorial changes The main technical changes are as follows.
--- Modified the technical specifications of the moving coil detector (see 5.4.1, 5.4 of the 2009 edition);
--- Increasing the technical indicators and test methods of the working inclination of the moving coil geophone (see 5.4.1 and 6.5.1.8);
--- Added the technical indicators and test methods of piezoelectric detectors (see 5.4.2 and 6.5.2);
--- Added the technical indicators and test methods of the dual detector detector (see 5.4.4 and 6.5.4);
--- Added the technical index and test method of the water pressure resistance of the geophone series (see 5.4.5 and 6.5.5);
--- Added a comprehensive parameter test method for moving coil geophones (see Appendix B).

3 Terms and definitions
The following terms and definitions apply to this document.
3.1 Moving coil detector
The seismic wave sensing device is designed by the principle that the coil moves in the magnetic field to generate induced electromotive force.
3.2 Piezoelectric geophone
A seismic wave sensing device designed using the principle of piezoelectric effect of certain substances.
3.3 Three-component geophone
It consists of three sets of seismic wave sensing devices whose working directions are perpendicular to each other and enclosed in the same casing.
3.4 Dual detection detector
A two-component seismic wave sensing device combined by a moving coil detector and a piezoelectric detector.
3.5 Velocity geophone
A seismic wave sensing device whose output voltage is proportional to speed.
4 Classification
4.1 Divided into working environment. land geophone, underwater geophone and underground (high temperature) geophone. […]
