摘　　要：海拉尔盆地具有多煤阶煤分布。煤系源岩生、排烃数据反映 :最好的煤层是南上段 ,其次是大上段 ;最有利的煤系泥岩是铜钵庙组与南屯组。各凹陷煤系源岩生气量大小顺序为 :呼和湖凹陷 >贝尔凹陷 >乌尔逊凹陷 >呼伦湖凹陷。各凹陷煤系源岩生油量多少顺序为 :乌尔逊凹陷 >呼和湖凹陷 >贝尔凹陷 >呼伦湖凹陷。煤系源岩排油量大小顺序为 :乌尔逊凹陷、贝尔凹陷、呼和湖凹陷、呼伦湖凹陷。可见 ,乌尔逊凹陷、贝尔凹陷、呼和湖凹陷具有良好的煤成油气勘探前景 ,是海拉尔盆地寻找煤成气。The coals with different coal ranks occurrence in Hailaer basin.According to hydrocarbon generation and expulsion data of coalbearing source rocks,the section n 2 is the best coal bed,then is the section d 2.In addition,the Tongbomiao Formation and the Nantun Formation are the most favorable coalbearing pelites.The sequence of gas generation amount of coalbearing source rocks in different depressions is :Huhehu>beier>Wuerxun>Hulunhu depression.The sequence of oil generation amount of source rocks in above depressions is :Wuerxun>Huhehu>Beier>Hulunhu depression.The sequence of oil expulsion amount of source rocks is :wuerxun>Beier>Huhehu>Hulunhu depression.Therefore,a good exploration prospect is existed in Wuerxun and Beier and Huhehu depressions where are the favorable areas to find oil and gas resources in Hailaer basin.
