摘　　要：根据泌阳凹陷古城、新庄油田不同的稠油物性特征及9口井油砂的氯仿沥青“A”、族组分及饱和烃色谱分析资料,对两油田稠油的地球化学特征及其稠变程度进行了分析和对比;研究了稠油族组分与距离新近系不整合面远近的相关性,探讨了稠油族组分与油层埋藏深浅、稠变程度高低的关系;指出了古城油田油藏的成藏时间早、新庄油田成藏时间晚是造成古城油田稠油稠变程度高于新庄油田的主要原因。According to different physical properties of heavy oil in Guchen and Xinzhuang oilfield in the northern slope of Biyang sag, and chlorofoum bitumen 'A', heavy oil com-plosition and saturated hydrocarbon chromatographic analytical data of oil - bearing sand in nine wells, the geo-chemical features and heavy oil consistency variance degree of the two oilfields have been compared and analyzed, the correlation between heavy oil complosition and unconformity which is close to Neogene has been studied, and the relationship between the heavy oil complosition and burying depth and variance degree has been discussed. The results show that the reservoir generation period is in accordance with the heavy oil consistency variance degree in this two oilfields, that is earlier hydrocarbon generation in Gucheng results in higher heavy oil consitency variancedegree than that of in Xinzhuang.
