防垢剂中Ca2＋对检验结果的影响

防垢剂是指能有效阻止或抑制油田水结垢的一类化学品,是油田水处理过程中常用的化学药剂。检测防垢剂主要指标碳酸钙垢防垢率时有时出现超过100%的异常现象。通过试验分析,发现防垢剂本身含有Ca2＋是造成这种异常现象的主要原因,防垢剂本身含的Ca2＋很大程度上影响着检验结果。

An Effect of Ca2+ in Anti-Scaling Agent on the Testing Result

Anti-scaling agent is one kind of chemicals that can effectively prohibit and restrict the water scaling in oilfields,and is also the chemical agent often used in the process of water treatment in oilfields.The unusual phenomenon of 100% sometimes emerges in detecting the main index of anti-scaling agents——the anti-scaling rate of calcium carbonate.But through the test and analysis,it is found that Ca2＋ in anti-scaling agent is the main reason that leads to this phenomenon.In other words,Ca2＋ in anti-scaling agent affects the testing results to a large degree.
