| 摘 要： | 在灼烧过的方解石和蒙脱石及灰岩和泥岩中分别加入同一种有机质配制成不同有机碳含量的样品进行热解和加水热压模拟实验,结果表明,海相碳酸盐岩的烃吸附量一般在0.35mg/g左右,变化在0.2~0.85mg/g之间;泥页岩烃吸附量一般在1.25mg/g左右,变化在0.46~2.62mg/g之间。高成熟—过成熟海相碳酸盐岩排烃下限TOC值为0.08%左右,成熟海相富烃碳酸盐岩排烃下限TOC值为0.3%左右,排烃下限TOC值与烃源岩吸附烃含量、干酪根类型及有机质成熟度有关。

| Abstract: | The pyrolysis and hydrous pyrolysis simulating experiments of samples with differentTOC which confected by burned calcite,smectite,limestone and mudstone added into the same organic mat-ters respectively,show that the content of absorpted hydrocarbon by the marine carbonate rock is usually about 0.35 mg/g and the range is 0.2-0.85 mg/g,the content of absorpted hydrocarbon by the shale is usually about 1.25 mg/g and the range is 0.46-2.62 mg/g.The lower limit of total organic carbon(TOC) is about 0.08% for hydrocarbon expulsion of high-to-over mature marine carbonate rock and about 0.3% for mature marine carbonate rock rich in hydrocarbon.The lower limit of total organic car-bon(TOC) for hydrocarbon expulsion is related with the quantity of absorpted hydrocarbon by source rocks,the type of kerogen and the maturity of organic matters. |
