准噶尔盆地东部北三台北4井二叠系油源油和阜康凹陷牧3井侏罗系油源油的混源地球化学实验结果表明,北三台西南斜坡的北27井原油与20:80(北4井:牧3井)的混合原油相近,侏罗系油源为主要贡献;三台凸起西侧的台22井原油与50:50的混合原油相近,为二叠系和侏罗系油源的共同贡献。

A geochemical test on mixed sources of crude oils was made.Oil samples used werePermian oil from Bei-4 well in Bei Santai area,East Junggar Basin and Jurassic oilcollected from Mu-3 well in Fukang Depression.The result shows that the crude oil fromBei-27 well on the southwest slope of Bei Santai area is similar to the mixed crude oils of20:80(20 parts of crude oil from Bei-4 well:80 parts of crude oil from Mu-3 well),andJurassic oil sources were the major contributor;the crude oil from Tai-22 well on twosides of Santai Uplift is similar to the crude oils of 50:50,and Permian and Jurassic oilsources were both the contributors.
