摘要： 塔里木盆地中央隆起带东段的塔东2井在寒武系储集层中获取少量稠泊。该稠油具有m(Pr)/m(Ph）高、伽马蜡烧含量高、24一降胆笛烧含量高、c28笛炕含量高、甲藻笛炕及三芳甲藻笛炕含量高、4甲基24一乙基胆笛炕及芳构化筒烧含量高的特点,地质分析与油源对比认为,原油来源于寒武系。原油中含有25降雀烧系列,表明原油曾发生生物降解作用；芳炬馆分中存在大量菲、葱、苯并惠、苯并荧惠、苗等化合物及流体包裹体均一化温度表明,原油曾经历了热蚀变作用。流体包裹体均一化温度结合埋藏史分析认为,塔东2井原油是在（450440)xl06a前形成的。

Abstract: A little heavy oil was acquired from Well TD 2 in Cambrian reservoir in the eastern central uplift of Tarim basin. The oil 1s characterized by high Pr/Ph, high gammacerane, high 24 norcholestane, high C28 sterane, high dinosterane and triaromatic dinosterane, high 4 methyl 24-ethyl cholestane and 4-methyl-24-ethyl triaromatic cholestane. The geologic analysis and oil-source correlation showed the heavy oil originated from the Cambrian source rock. The 25-norhopane series of the oil indicated that the oil had been hiodegraded. A large amount of the phenanthrene, flnoranthene, henzoanthracene, henzofluoranthene, pyrene and the homogenization temperature of the fluid inclusion suggested the oil has suffered thermal lteration. Combined with the burial history of Well TD-2, the homogenized temper- ature of the fluid inclusion indicated the oil formed dming (450~44)×106a．
