油基钻屑的含油率和/或含油量的测量方法及其应用
摘要：
本发明涉及一种处理后的油基钻屑的含油率和/或含油量测量方法，包括如下步骤：1)用不含氢原子的有机试剂与不同质量的多种油基钻井液基础油混合，并进行核磁共振测量，建立T2谱油峰面积(Si)与基础油质量(Mi)的线性方程：Mi＝k×Si+b；2)称取处理后的油基钻屑，将其质量记录为M1，倒入容器中；3)量取四氯化碳分析纯溶液，将其体积记为V1，倒入步骤2)所述的容器中萃取；4)从步骤3)的容器中量取体积V2的溶液，条件是V2
摘要（英）：

The invention relates to a method for measuring the oil length and/or oil content of treated oil-based drilling cuttings. The method includes the following steps that 1, an organic reagent which does not contain hydrogen atoms is mixed with various types of oil-based drilling fluid base oil with different masses, nuclear magnetic resonance measuring is carried out, and the linear equation that Mi=k*Si+b of the T2 spectrum oil peak area (Si) and base oil mass (Mi) is established; 2, the treated oil-based drilling cuttings are weighed, the mass of the treated oil-based drilling cuttings is recorded as M1, and the treated oil-based drilling cuttings are poured into a vessel; 3, a carbon tetrachloride analytically-pure solution is measured, the volume of the carbon tetrachloride analytically-pure solution is recorded as V1, and the carbon tetrachloride analytically-pure solution is poured into the vessel in the step 2 for extraction; 4, a solution with the volume of V2 is measured from the vessel in the step 3 under the condition that V2
