摘　　要：该文采用燃烧法与抽提法对广元利州区竹园镇—羊木镇片区天然沥青矿进行沥青含量测试,根据样品测试结果进行对比分析,获得了如下认识:燃烧法和抽提法均能有效测定沥青含量;岩性改造型天然沥青含量基本不受测试方法影响,构造圈闭改造型天然沥青矿采用抽提法检出值更高;沥青含量越高,燃烧法和抽提法差异越小。The bitumen content of natural bitumen ore in Zhuyuan Town and Yangmu Town area of Lizhou District,Guangyuan was measured by combustion method and extraction method.The results show that both combustion method and extraction method can determine asphalt content effectively.The content of natural bitumen of the lithologic modified type is basically not affected by the test method,and the extraction method is higher for the natural bitumen of the structural trap modified type.The higher the content of asphalt,the smaller the difference between combustion method and extraction method.

关 键 词：广元地区 燃烧法 抽提法 天然沥青矿 沥青含量
