江汉油区注入水水质标准控制指标评价和优选

Evaluation and Optimization of Control Indications of Injected Water Quality in Jianghan Oil Region

按照国际石油行业的腐蚀分类标准和国内有关注水水质标准文献,对注水水质标准控制指标进行评价和优选,取得了良好的效果。具体的做法是:采用岩心流动试验确定悬浮固体含量、颗粒直径中值、含油量、铁细菌和腐生菌五项控制指标;采用旋转腐蚀挂片实验确定硫酸盐还原菌和平均腐蚀率指标;采用结垢预测和敏感性实验确定平均结垢率和总矿化度指标。

According to corrosion classification criteria in international petroleum industry and documents concerning injected water quality in China, the author evaluates and optimizes control indications of injected water quality standards and gets good effects. The specific methods ： 1, to ascertain five control indications including suspended solid content, grain diameter median, oil content, iron bacteria and saprophytic bacteria by carrying out the experiment of core flow; 2. to ascertain indications of sulfate reducing bacteria and average corrosion rate by carrying out the experiment of revolving corroded test pieces; 3. to ascertain indications of average scaling rate and total mineralization degree by carrying out the experiment of scaling prediction and sensibility.
