Abstract: Two kinds of new high temperature detergent were synthesized, and the scale of sample dissolution experiment under the condition of the well was done to determine the best ratio of compound. Then performance of the descaling fluid was evaluated. The results showed that the detergent has good corrosion for three kinds of scale at high temperature. At the same time, the study found that the core permeability had been significantly improved when the detergent was used together with acid. 

摘要： 合成两种新型高温除垢剂 A - 1、 B - 1, 并模拟地层环境进行垢样溶蚀实验, 确定了两种除垢剂的最佳复 配比例, 并对复配的除垢液进行性能评价。结果表明, 在高温下除垢液对3种垢均有较好的溶蚀能力, 同时研究发现 将除垢与酸化相结合能显著地改善岩心渗透率。
