摘　　要：通过对准东地区石炭系烃源岩评价和油源对比研究认为,彩25井区、彩参1井和吉15井原油为石炭系滴水泉组和巴塔玛依内山组煤系的煤成油;阜10井原油源于二叠系平地泉组烃源岩;彩31井和沙丘6井原油为二叠系烃源岩和石炭系烃源岩的混油;彩25井区和吉15井原油为在弱氧化-弱还原环境下形成的煤成油;而彩参1井原油则为在还原-强还原还境下形成的煤成油。Through evaluation of Carboniferous hydrocarbon source rocks and correlation of oil sources in Jundong area(eastern Junggar basin),it is indicated that Well Block Cai25,Well Caican1and Well Ji15contain crude oil which belongs to coal-derived oil from coal measures in Carboniferous Dishuiquan formation and Batamayineishan for-mation,the crude from Well Fu10was originated from source rocks of Permian Pingdiquan formation;while those from Well Cai30and Well Shaqiu6came from mixed hydrocarbons of Permian and Carboniferous source rocks.Meanwhile,crude oil from Well Block Cai25and Well Ji15are coal-derived oil which formed under the weak oxido-reduction envi-ronment,that from Well Caican1is one formed under the reduction-strong reduction environment.
