New Experimental Methodology Research for Adsorbed Gases on Hydrocarbon-source Rocks
摘要
Abstract
As compared to the device developed by our predecessors, the newly established adsorbed gas degasifica- tion-eollection device has a series of advantages such as wide sample application range, large sample inlet, high vae- cure, short-time sample smashing, low crushing temperature and water-free gas collection, which make sure the geo- chemical characteristics of acquired adsorbed gas sample is the same as the adsorbed gas on corresponding hydrocar- bon-source rock. The results show that the acquired adsorbed gases are composed mainly of hydrocarbon gas and car- bon dioxide gas, with the hydrocarbon gas accounting for more than 80%, and can be measured reliably for their δ13C1 -δ13C3 data, evenδ13C4 -δ13C5 data. The results of carbon isotope test analysis satisfy the needs for the geochem- ical study and application of adsorbed gases. The above new techniques of experimental geochemistry establish the new direct nature gas-source correlation method, prove that the old usual method of indirect nature gas-source correla- tion is scientific and authentic, and set up the experimental basis of the research and application of adsorbed gas on hydrocarbon-source rock.关键词
