Some standard content:
SY/T 5117-1996, Petroleum and Natural Gas Industry Standard of the People's Republic of China, Rock Pyrolysis Analysis Method, 1996-12-31, issued, China National Petroleum Corporation, implemented on 1997-09-01, SY5117-86 "Rock Pyrolysis Analysis Method" has been implemented for ten years since June 30, 1986. The foreign rock pyrolysis instrument has developed from type I and II to type V, and the domestic rock pyrolysis instrument has DH910 type geochemical recording instrument series and YQ-type oil and gas display analyzer series. Although SY/T6015-94 "Rock Pyrolysis Analysis Method for Oil and Gas Display Analyzer" has been issued, it still cannot keep up with the rapid development of rock pyrolysis instruments and their analysis methods. Therefore, it is necessary to revise SY5117-86 "Rock Pyrolysis Analysis Method". The principles of revision are: 1. The revised standard is universal and applicable to all types of rock pyrolysis instruments, both imported and domestic. 2. The revised standard is applicable to both pyrolysis analysis of source rock and reservoir rock. This standard replaces SY5117-8G from the date of publication. This standard is proposed and managed by the Petroleum Geology Exploration Professional Standardization Committee.

This standard specifies the analysis conditions, required steps, precision and calculation parameters for pyrolysis analysis of rocks. This standard is applicable to the determination of gaseous hydrocarbons, liquid hydrocarbons, pyrolytic hydrocarbons, carbon dioxide and residual organic carbon in mudstone, carbonate rock and sandstone. It is also applicable to the pyrolysis analysis of other rocks 2 Cited standards

The gaseous hydrocarbons, liquid hydrocarbons and pyrolysis hydrocarbons discharged during the heating of the sample by carrier gas ammonia, hydrogen or nitrogen flow are detected by oxygen flame ionization detector, and the carbon dioxide discharged in the meantime is detected by thermal detector or infrared detector. The carbon dioxide generated by the oxidation of residual organic matter after pyrolysis is also detected by thermal conductivity detector or infrared detector. The carbon dioxide generated by oxidation is catalytically hydrogenated to generate methane and then detected by hydrogen flame ionization detector. 5 Reagents, materials and standard substances
