中文摘要In th is paper a thermograv im etry-diffe rentia l therm a l ana lys is m e thod coupled w ith chrom atography( TG-DTA-GC) has been adopted to sim ulate the gene ration o f g aseous hydrocarbons from different hydrocarbon source rocks such as coa ls, m udstones, and carbonate rocks w ith d ifferent ma tur ities. The temperature programm ing for the rmal simulation exper im ent is 20e /m in from amb ient tem pera ture to 700e . A s v iew ed from the quantities and composition o f generated gaseous hydrocarbons at different tempe ratures, it is shown tha t low-matu re coal has exper ienced the strongest exo therm ic reaction and the h ighest loss o fw e ight in wh ich the first exotherm ic peak is relatively low. Low-m a ture coa l sam ples have stronger capab ility of generating gaseous hydrocarbons than high-m ature samp les. The am ounts and composition of g aseous hydrocarbons gene ra ted are c losely re lated no t only to the abundance of organ ic carbon in sou rce rocks, bu t a lso to the type of kerogen in the source rocks, and the ir therm a lma tur ity. In the present h ighly mature and over-m ature ro ck sam ples organ ic ca rbon, probab ly, has a lready been exhausted, so the production o f g aseous hydrocarbons in la rge amoun ts is impossible. The contents o f heavy com ponents in gaseous hydrocarbons from the source rocks conta in ing type-Ⅰ and-Ⅱ kerog ens a re gene ra lly high; those of light componen ts such as m e thane and ethane in g aseous hydrocarbons from the source rocks w ith Ⅲ- type kerog ens a re h igh as w el.l In the cou rse o f therma l simu lation of carbona te rock samples, la rge amounts of gaseous hydrocarbons w ere produced in a high tempe rature range.
