A PRELIMINARY STUDY ON THE ACTIVATION ENERGY PARAMETERS OF GLOEOCAPSOMORPHA KEROGEN IN ORDOVICIAN SOURCE BEDS

The distribution of Low Paleozoic source beds,especially carbonate rock strata,is very wide in our country.But the geochemical evaluation for the distributive area of carbonate rocks is always a vulnerable spot.One of the important reasons is that it is difficult to obtain the accurate geochemical parameters due to the high overmaturity of carbonate rocks.In this pater,the lowmatured Gloeocapsomorpha kerogen of general distributive significance in Ordovician source beds is selected for pyrolysis experiment.A series of dynamic parameters(activation energy E,the changing relationship of frequency factor A to degradability X)of chemical reactions obtained have an obvious use for reference to the correct evaluation of oil/gas potential and hydrocarbon generation/hydrocarbon discharging history in Low Paleozoic carbonate rock strata.
