Rock pyrolysis instrument

Principles and Applications

Under programmed heating conditions, the rock is heated to evaporate the oil and gas components, while the kerogen and high molecular weight bitumen are thermally decomposed into hydrocarbonsFIDQuantitative detection and analysis revealed three peaksS0TheS1TheS2andTmaxOr WufengS0TheS1TheS21TheS22TheS23, as well as other derived parameters;The residual organic matter in the sample after pyrolysis is heated and oxidized toCO2By addingH2Catalytic generationCH4, byFIDQuantitative testing resultsS4Furthermore, the total organic carbon content in the sample can be calculated to quickly evaluate the oil production potential, maturity, organic matter type, and oil and gas content and properties of the source rock and reservoir rock. Analyze the results according to relevant national standards.
