三江盆地绥滨坳陷中生界生烃潜力

利用三江盆地绥滨坳陷现有钻井的有机碳和热解数据, 从有机地球化学方面对坳陷中生界主力煤系烃源岩的生烃特征及潜力进行了研究。结果表明: 研究区有机显微组分以惰质组为主，但壳质组和腐泥组中存在较多富氢组分的孢子体、壳屑体和矿物沥青基质。有机质类型以Ⅲ型为主，其次为II型。其中城子河组和穆棱组有机质类型相对较好，为2套具生烃潜力的煤系烃源岩。烃源岩有机质成熟度较高，RO值变化范围主要集中在0.5%～1.0%之间，绝大部分都已进入生油阶段，且部分烃源岩已进入高成熟-过成熟阶段，转为以生气为主。

Hydrocarbon-generating Potential in Mesozoic Suibin Depression of Sanjiang Basin

Using existing well drilling data of organic carbon and thermal decomposition in Suibin depression of Sanjiang basin,from the organic geochemistry aspect we conducted the research of hydrocarbon characteristic and hydrocarbon-generating potential of main coal-bearing source rock from Mesozoic of the depression.The results indicated that in research area vitrinite is the main organic maceral while abundant sporinite,exitinite and fluorescence,which have rich hydrogen components,in liptinite and saprope.The o...
