摘要

塔里木盆地塔中地区原油总体上相对富含链烷烃,贫芳烃,苯的含量很低,正己烷和己烷含量较高,处于高成熟阶段,所经历的最高温度为115~128℃,除个别井原油表现为高K1值外,其他样品K1值与M ango所做的结论一致。

Abstract

Light hydrocarbons of crude oils in Tarim basin Tazhong area overall relatively enrich the alkanes and is deficient in aromatic hydrocarbons.The benzene content is very low,in other hand the normal hexane and the hexane content are high.All of the Tazhong area crude oil are maturity oils.That K_1((2-MC6+2,3-DMC5)/(3-MC6+2,4-DMC5)) distributes at normal range is consistent with the conclusion which reported of the Mango’s light hydrocarbon in a majority of crude oils except that specific well behave highly.

Key words： Tarim basin; Light hydrocarbon; Heptane value; Isoheptane value; Mango’s light hydrocarbon parameters.
