摘要： 利用咔唑类非烃化合物作为油气运移示踪剂,探讨了塔中地区志留系可动油的运移方向。对塔中地区志留系可动油的吡咯类化合物的丰度、参数的变化规律的研究结果表明,塔中地区志留系可动油侧向运移分馏效应不显著,具有近源性特点。志留系可动油主要来源于满西地区和塔中北斜坡的寒武-奥陶系烃源岩,向南东-南的方向首先进入塔中47号构造,然后依次向塔中11、塔中12-50及塔中16号等构造侧向运移。垂向上,志留系可动油有自下而上运移的趋势。油气运移过程受区域构造控制,运移方向与志留系主要断裂走向一致。

Abstract: Carbazole non-hydrocarbon compounds are used as tracers for investigation of Silurian oil migration direction in Tazhong area, Tarim basin. The results from their abundances, parameter variations indicate that the movable oil has unremarkable distillation efficiency of lateral migration and proximal feature similar to the Cambrian-Ordovician source rocks in Manxi area and slope of northern Tazhong area, with lateral migration directions towards Tazhong 47 from SE to S, and then Tazhong 11, Tazhong 12-50 and Tazhong 16 structures. Vertically, the movable oil migration of Silurian has a tendency from lower to upper sections. The process of the oil migration is controlled by regional structures and the direction of the oil migration is consistent with the strike of major faults of Silurian.

Key words: Tarim basin, Silurian, petroleum migration, carbazole compound
