Abstract

Abstract: Through evaluation of Carboniferous hydrocarbon source rocks and correlation of oil sources in Jundong area (eastern Junggar basin),it is indicated that Well Block Cai 25,Well Caican 1 and Well Ji 15 contain crude oil which belongs to coal-derived oil from coal measures in Carboniferous Dishuiquan formation and Batamayineishan formation, the crude from Well Fu 10 was originated from source rocks of Permian Pingdiquan formation; while those from Well Cai 30 and Well Shaqiu 6 came from mixed hydrocarbons of Permian and Carboniferous source rocks. Meanwhile, crude oil from Well Block Cai 25 and WellJi 15 are coal-derived oil which formed under the weak oxido-reduction environment, that from Well Caican 1 is one formed under the reduction-strong reduction environment.

Key words: Junggar basin, east, Carboniferous, oil sources, geochemistry
