Scope

Scope: This document specifies the composition, model naming method, requirements, test methods, inspection rules, marking, packaging, transportation, and storage of piezoelectric detectors for marine seismic exploration solid cables (hereinafter referred to as detectors). This document is applicable to the design, manufacture, and acceptance of piezoelectric detectors for marine seismic exploration solid cables. Main technical contents: (1) Sound pressure sensitivity M (ref 1V/μPa) 192.5±1.5 (dB) Determined according to the equipment's technical requirements and taking full account of its service life. (2) Free capacitance CT (1kHz) 8200±820 (pF) Determined based on the equipment's circuit matching and combined with the detectors' aging and failure conditions. (3) Insulation resistance R ≥2×109Ω Determined according to the actual use environment requirements and used as a criterion for the waterproofness of piezoelectric detectors.
