【摘要】 岩屑荧光录井中含油岩屑的干燥方法不同,对原油荧光分析具有哪些影响?它已涉及到干燥方法的优选。该文用实验的方法,对不同类型的含油岩样和现场岩屑,分别在加入和不加入强荧光钻井液添加剂的情况下,进行了多种干燥方法的对比荧光测试。实验结果表明,干燥方法不同,岩样的干燥速率不同,岩样中原油荧光特性各异。分析认为,对于老岩样,50℃烘干最好;对于新捞取的砂样,50℃烘干和太阳晒干效果相似,而且均好于其它方法。更多还原

【Abstract】 Drying method of cuttings can make much influence on fluorescence analysis of crude oil contained in drilling cuttings. In this paper, comparative fluorescence tests of many drying methods have been taken on field cuttings and different types of core samples under two conditions which have the extraneous fluorescence interference or not. The results show that the drying rates and fluorescence characteristics of field or modified cuttings are different from one another using different drying methods. It is considered that the method of drying by oven of 50℃ is superior to the other for the old samples and both methods of drying by oven of 50℃ and drying under the sun have the similar effects which are also superior to other methods.更多还原
