钻井液用重晶石粉密度测定不确定度的评定

Evaluation on the Uncertainty in Determining the Density of Drilling Fluid Barite Powder

在钻井液化学剂性能的检验工作中,各种参数的数学关系比较复杂,且很难搜集到该方面不确定度的评定先例借鉴。如何对测量结果的不确定度进行合理的评定是困扰检测实验室的一个难题。依据测量不确定度的评价原则,通过实例,简要阐述了钻井液用重晶石粉密度测量不确定度的评定方法,对钻井液化学剂检测领域测量不确定度评定具有借鉴意义。

In the inspection for chemical properties of drilling fluid,mathematical relationship of various parameters are very complex,and it is also difficult to find out the precedent evaluated examples for reference.So,how to evaluate the uncertainty of inspection result rationally has been a difficult issue puzzling the inspection laboratory.In this paper,according to the evaluating principles of measurement uncertainty,the evaluation methods about the uncertainty of determining the density of drilling fluid barite powder have been expounded briefly,which is of significance for the evaluation of measuring uncertainty in the inspection field of drilling fluid chemicals.
