Fremgangsmåte og anordning for å bestemme petroleumsegenskaper ved geologiske sedimenter

摘要

The method of determining the petroleum characteristics of a geological sample involves subjecting the sample to rapid heating in a non-oxidising atmos. to below 200 degrees C, holding at this temp. for a certain time and then heating at 0.2-50 degrees C/minute to 600-850 degrees C. The method includes continuously measuring the CO2 and CO emissions at each instant of the sample heating period, these measurements pref. being interpreted together to differentiate between organic oxygen and mineral oxygen. Also claimed are: (i) an appts. for carrying out the above method; and (ii) a petroleum evaluation system for geological sedimentary samples, the system including the above appts. and a PC with associated display, printing and input peripherals.
