中文摘要：

双城太平川地区为松辽盆地北部重要的油气勘探区域。对该区扶、杨油层原油和青1段、青2＋3段、嫩1段暗色泥岩地球化学特征的综合分析表明，研究区原油为同一族群，主要以青1段暗色泥岩为烃源层，部分青2＋3段泥岩可作为烃源层有部分生烃贡献，但限于三肇凹陷与朝阳沟阶地，嫩1段不可能作为扶、杨油层的烃源层。另外，三肇凹陷与朝阳沟阶地的扶、杨油层原油主要以三肇凹陷和朝阳沟阶地青1段泥岩为烃源灶；长春岭背斜带与王府凹陷的原油主要以王府凹陷青1段泥岩为烃源灶，三肇凹陷与朝阳沟阶地烃源灶也对长春岭背斜带原油有部分贡献。

英文摘要：

Shuangcheng- Taipingchuan is an important petroleum exploration area in the north of Songliao Basin. By synthetically analyzing geochemical characteristics of petroleum and mudstone, it indicates that petroleum belongs to the same population in Fuyu and Yangdaehengzi oil layer. The studied petroleum mainly comes from Qing 1 member and partly from Qing 2 ＋3 member mudstone of the Sanzhao Sag and the Chaoyanggou Bench, but not from Nen 1 member mudstone. Moreover, oil of the Sanzhao Sag and the Chaoyanggou Bench mainly comes from their Qing 1 member hydrocarbon source kitchen. Petroleum of the Changchunling Anticline Belt and the Wangfu Sag mainly comes from Qing 1 member hydrocarbon source kitchen in the Wangfu Sag. Qing 1 member hydrocarbon source kitchen of the Sanzhao Sag and the Chaoyanggou Bench also has partial contribution to petroleum in the Chang chunling Anticline Belt.
