Abstract The quality monitoring and evaluation of oil and gas geochemical analysis and testing are not detailed enough in the current standards and specifications, and there are also some differences in quality requirements. Based on a comparison of related contents of the effective national standards, industry standards and enterprise standards and combined with many years of experience in quality management, this paper systematically analyzes and evaluates the monitoring and evaluation methods commonly used in oil and gas geochemical analysis and testing.At the same time,based on the comparative study of the allowable error and the qualified rate of each standard, it is pointed out that the other standards are lower than the national standards in quality and need to be revised in time. This paper also calls for speeding up the development of standard samples for oil and gas geochemical exploration, ensuring the accurate tracing of quantitative values, and promoting and improving the quality monitoring level of oil and gas geochemical analysis and testing.
