摘要: 为查明准噶尔盆地吉木萨尔凹陷中二叠统芦草沟组烃源岩古沉积环境演化过程,对27块烃源岩样品进行主量元素、微量元素测试,并结合生物标志物、碳酸盐岩δ18O数据,对芦一段、芦二段沉积期的古氧相、古盐度、古气候以及古水深演化进行了研究。结果表明:吉木萨尔凹陷芦草沟组一段正构烷烃主峰碳以nC17为主,相对富集伽马蜡烷,Ph,β胡萝卜烷,V,U,FeO,Sr,Mg和Ca等,碳酸盐岩δ18O偏正,为干旱气候咸化贫氧—厌氧沉积,部分层段为半咸水沉积,MnO/TiO2指示其古水深较深;芦二段正构烷烃主峰碳以nC21和nC23为主,相对富集Pr,Fe2O3,Al,Ti和C24四环萜烷等,总体为湿润气候半咸水贫氧沉积,偶尔处于干旱咸化沉积,古水深相对较浅。该研究成果表明芦一段可作为研究区下一步勘探的重点层系。
