植物酚类钻井液处理剂的电导特性研究

Study on the electrical conductance characteristics of plant-based phenolic compounds as drilling fluid additive

通过实验研究了混合态的兴安落叶松植物酚类钻井液处理剂的电导特性,提出了利用配位-电导滴定曲线来计算混合态植物酚类化合物及其改性产物中组分的相对含量的新方法,并根据电导滴定曲线的变化规律,分析了混合态植物酚类改性产物的电化学特性,进而解释了用纯化的单酚或多酚的理化性质难以解释的酚类油田化学品的一些使用特性。

The electrical conductance characteristics of phenolic compounds from Chinese larch tree were studied in this work. A new method was proposed to calculate relative amount of component in mixed plant - based phenolic com- pounds and its modified production by the coordination - conductance titration curve. According to changing laws of con- ductance titration curves, it was analyzed the electrochemical characteristic of the modified production and interpreted some operational performances of phenolic oilfield chemicals which was difficultly explained by the physical - chemistry proper- ties of pure monophenol or polyphenol.
