| 摘 要： | 针对三塘湖盆地石炭系和下二叠统的烃源岩的有机丰度、有机质类型、成熟度、分子地球化学差异分析,表明:哈尔加乌组和芦草沟组烃源岩有机质丰度最高,卡拉岗组和巴塔玛依内山组烃源岩次之.卡拉岗组有机质类型以Ⅰ、Ⅱ1类为主,形成咸化-还原环境.处于低熟-成熟阶段;哈尔加乌组主要为Ⅱ1、Ⅱ2类,形成于淡水-弱还原环境.处于成熟阶段;下石炭统主要为Ⅱ2类,处于高成熟-过成熟阶段. |

| Abstract: | We carried out a study on the source rock of both Carboniferous and Lower Permian in Santanghu Basin, including organic-matter abundance, type and maturity, along with molecular geochemical difference. Results show that: (1) in source rock of both Haerjiawu and Lucaogou formations, the organic-matter abundant is the highest, second for both Kalagang and Batamayinei formations; (2) for Kalagang Formation, the organic-matter types mainly include I and II1, forming in a saline-reduction environment and being i... |
