阅读说明：本技术 油田应用中的铁硫化物移除 (Iron sulfide removal in oilfield applications ) 是由 陈涛 王齐伟 化权·弗兰克·张 于 2018-05-23 设计创作，主要内容包括：将在碳素钢管上的铁硫化物溶解以得到螯合铁通过用包含铁螯合剂和添加剂的组合物处理碳素钢管实现。添加剂包括氧化剂和碱中的至少一种。铁螯合剂与添加剂的重量比在50:1至5:1的重量范围内。(Dissolving the iron sulfide on the carbon steel tube to obtain chelated iron is achieved by treating the carbon steel tube with a composition comprising an iron chelator and an additive. The additive includes at least one of an oxidizing agent and a base. The weight ratio of the iron chelator to the additive is in the range 50:1 to 5:1 by weight.)
