摘　　要：根据原油中的3类极性化合物(烷基咔唑类化合物、烷基二苯并噻吩类化合物和烷基苯酚类化合物)在运移过程中与固相的吸附机理及其吸附性特征,探讨了这3种极性化合物与固定相通过氢键或者范德华力等作用力而被吸附,并导致原油中极性化合物浓度随着运移距离的增大逐渐降低的现象。通过对塔河油田22个奥陶系原油样品中3类极性化合物进行定量分析,结果显示其浓度具有从南向北、从东向西逐渐降低的规律,指示出塔河油田奥陶系原油的运移具有从南部和东部指向主体区的趋势。Alkyl-carbazole,alkyl-dibenzothiophene and alkyl phenol are prone to form hydrogen bonds and vander Waals bonds with solid phase because of the existence of strong electro negativity atoms such as N,S and O,and the concentrations of the compounds decrease during the process of oil migration.The analysis results of the concentrations of alkyl-carbazole,alkyl-dibenzothiophene and alkyl phenol of 23 crude oil samples in Ordovician age collected from the Tahe Oilfield indicate the concentrations decreases from south to north,and from east to west,which implies that Ordovician crude oil in Tahe Oilfield migrated from southern and eastern parts to the main part.
