摘　　要：物源方向的准确判断对成功预测岩性油气藏分布，提高油气藏勘探程度具有重要意义。采用地球化学油气二次运移方法对鄂尔多斯盆地西南部的镇北地区长3油层组物源方向进行了研究，并与传统研究结果进行了对比。结果表明，地球化学油气二次运移方法和传统研究方法的研究结果具有一致性，研究区物源为盆地的西南部。该方法丰富了传统物源判断方法，在克拉通沉积盆地具有很好的应用前景。The accurate judgment of source direction has great significance for the successful prediction of lithologic resmwoir distribution and the enhancement of exploration degree of hydrocarbon reservoirs. Therefore, the geochemical oil ＆ gas second-migration method has been adopted to investigate the source direction of Chang-3 reservoir group in Zhenbei area in the Southeast of Ordos Basin, comparing with the traditional research results. The results show that the research results obtained by using the geochemical oil ＆ gas migration method and the traditional research method have consistency, and it is found that the source direction of the studied area is the southwest of the basin. This method enriches the traditional source judgment method and has very good application prospect in craton basins.
