对钻井液化学剂铬离子含量分析研究

Analyses of the Chromium Content in the Chemical Agent Used as Drilling Liquid

利用实测的实验数据对普光油气田钻井液化学剂中铬离子含量进行了分析,发现了造成铬离子环境污染的主要原因,提出规范产品执行标准的建议。指出,在产品使用中对环境造成危害的游离铬和络合铬的检测方法及含量进行要求,制定相应的技术规范,严格控制全铬、络合铬、游离铬的含量。

The chromium content in the chemical agent used as drilling liquid in Puguang oilfields was analyzed according to the practical experiment data. Then the main causes of chromium environment pollution have been found out, followed by some advice to normalize the executive standard of products. Therefore, it is necessary to make strict demands on the detection methods and content of free chromium and complex-chromium polluting the environment in the use of products, in other words, to establish the corresponding technological standards and strictly control the content of pure chromium, complex-chromium and free chromium.
