通过对梨树断陷不同地区、不同层位烃源岩、原油的地球化学特征分析，明确了主力烃源岩特征和原油地球化学特征。在生物标记化合物、碳同位素分析对比的基础上，认为梨树断陷中的原油主要来源于Ⅱ1型生烃母质，苏家屯地区有部分Ⅲ型生烃母质来源原油的混入。油源对比表明，梨树断陷原油主要来自沙河子组烃源岩，部分地区有营一段烃源岩的贡献。

According to the geochemical features of source rocks and crude oils from different strata and different area in the Lishu Fault Depression, the main source rock features and crude oil geochemical characteristics have been concluded. The analyses of biomarker compound and carbon isotope show that crude oils in the Lishu Fault Depression mainly generated from parent materials of type Ⅱ1 , while in Sujiatun area some crude oils which generated from parent materials of typeⅢmixed in. Oil and source correlation proves that crude oils in the Lishu Fault Depression mainly generated from the Shahezi Formation, while the 1st member of Yingcheng Formation al-so contributed in some area.
