  • 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.
