伦坡拉盆地牛堡组烃源岩综合评价

Comprehensive Evaluation on Source Rocks of Niubao Formation, Lunpola Basin

通过对伦坡拉盆地牛堡组烃源岩的展布、有机质丰度、有机质类型及成熟度等分层系进行研究及综合评价,指出盆地中西部烃源岩条件较东部烃源岩更好,且牛堡组二段烃源岩是伦坡拉盆地品质最好的一套主力烃源岩,最终指出了伦坡拉盆地中央凹陷带具有较好的勘探潜力。

For source rocks of Niubao Formation, Lunpola Basin,the distribution, and the organic-matter abundance, type, and maturity were comprehensively analyzed and evaluated. Results show that(1) the source-rock conditions in central and western basin are much better than those in eastern basin;(2) the source rocks of Niubao 2 Member are the main ones with best quality; and(3) there are brighter prospects for further exploration in central sag of Lunpola Basin.
