油田水常规分析主要是化验油田水中的六项离子的含量,测定水样的PH值、矿化度等,分析依据《油气田水分析方法》。在化验分析过程中,误差是客观存在的,要提高分析结果的准确度,就必须考虑在分析中可能产生的各种误差,采取有效措施,将化验误差降至最小限度。本文主要是从取样、分析操作、数据处理等方面找出误差的产生的原因,并制定相应的对策,以提高分析结果的准确度。 The routine analysis of oilfield water is mainly the content of six ions in the laboratory oilfield water, and the PH value and salinity of the water sample are determined. The analysis is based on the “oil and gas field water analysis method”. In the process of laboratory analysis, the error is objective. To improve the accuracy of the analysis results, various errors that may occur in the analysis must be considered and effective measures should be taken to minimize the laboratory error. This article mainly from the sampling, analysis, data processing and other aspects to find out the reasons for the error, and to develop appropriate countermeasures to improve the accuracy of the analysis results.
