摘要
该区早白垩世多巴组烃源岩岩石类型、有机质丰度、有机质类型、有机质热演化程度等方面研究表明,多巴组烃源岩有机质丰度偏低,有机质以腐泥型和腐殖腐泥型为主,有机质的热演化以高成熟为主,总体评价为较差烃源岩.该成果为在措勤盆地进一步开展油气勘探提供可靠的地质资料。
hina National Petroleum Corporation has been conducting petroleum exploration onQingzang plateau since 1994. From 1994 to 1997, authors have been there for four times,engaged in geological investigation of oil and gas. Showed through some researches on thelower Cretaceous Duoba formation scud rocks including rock type, organic abundance,organic type and the level .of organic evolution, the organic abundance is lower, the organictypes mainly include sapropel type and humic-sapropel type and the organic evolution ischiefly in high mature stage; so the source rocks is totally poor. The studies provide reliablegeological information for further oil and gas exploration in Cuoqin basin.
