选取3个国外克拉通盆地，即西西伯利亚盆地、巴黎盆地和伊利诺斯盆地，与鄂尔多斯盆地进行对比。鄂尔多斯盆地作为发育在坳拉谷基底之上的克拉通盆地，具有含丰富油气资源量的地质基础。鄂尔多斯盆地为中生代陆相沉积，其烃源岩的分布相对于整个盆地较为局限，圈闭类型较为复杂多样，除此之外的其他地质因素均比较相似。根据盆地对比估算得到鄂尔多斯盆地中生界的探明石油储量为17.21×108 t（据西西伯利亚盆地）、22.67×108 t（据巴黎盆地）和24.40×108 t（据伊利诺斯盆地），表明鄂尔多斯盆地中生界具有很大的资源潜力和勘探前景。

West Siberia,Paris and Illinois basins were chosen to do comparison with Ordos Basin.The Ordos Basin is a cratonic basin that was developed above aulacogen base,so it has good tectonic basis for accumulating abundant oil and gas resources.Besides continental sedimentation,limited distribution of source rocks and com-plex trap types,all the other geologic conditions of Mesozoic Ordos Basin are similar to those of the three foreign basins.The results of basins comparison and calculation show that the Mesozoic Ordos Basin can possess proved oil reserves as 17.21 ×108 t (based on West Siberia Basin),22.67 ×108 t (based on Paris Basin)and 24.40 ×108 t (based on Illinois Basin),indicating that the Mesozoic Ordos Basin has great oil resource potential and exploration prospect.
