| 摘 要： | 运用全岩光片、干酪根光片、干酪根薄片和光薄片等手段,对塔里木盆地下古生界烃源岩有机显微组分进行观察研究,对各种组分进行特征描述,根据显微组分的成因及光性特征,将其分为原生形态有机质、原生无形态有机质及次生有机质3类,并在此基础上确定了下古生界烃源岩有机显微组分的加权系数。应用该方案对塔里木盆地孔雀河1井O2+3q烃源岩有机质类型进行分析,6个样品中有1个为Ⅰ型,3个为Ⅱ1型,2个为Ⅱ2型。

| Abstract: | In this paper,the organic macerals from the Lower Paleozoic hydrocarbon source rock in the Tarim Basin were observed and studied by using the polished thick sections of whole-rock and kerogen as well as the polished thin sections of rock and kerogen.Characteristics of the organic macerals were described.These organic macerals were classified as three types according to the genesis and optical pro-perties of them.They are primary morphologic organics,non-morphologic organics and secondary organics.Based on the above,the weighting coefficient every organic maceral in the Lower Paleozoic hydrocarbon source rock was determined.Finally,this classification method was applied to the evaluation of the Middle-Upper Ordovician hydrocarbon source rock in the Well Kongquehe 1,the Tarim Basin.One of the six samples is determined as type I,two of them are type Ⅱ1 and the other two samples are type Ⅱ2. |
