The SEG(Society of Exploration Geophysicists)in the United States establishes seismic record polari-ty standards as SEG polarity and SEG anti-polarity,ensuring the uniformity of original field records.In seismic exploration projects,oil companies provide explicit instructions and requirements for instrument polarity,vibro-seis polarity,and seismic data polarity in advance.Polarity errors can lead to significant quality incidents.Hence,special attention must be given to polarity testing after construction audits,routine inspections of acquisi-tion equipment,and replacement of relevant acquisition equipment components.This paper,in conjunction with a field seismic acquisition project and using the Sercel system as a case study,employs the third-party testing soft-ware Testif-i to examine and dissect SEG polarity-related knowledge.The goal is to provide guidance in the actu-al production process and prevent quality incidents arising from polarity issues.
