- 摘要:
- 目前油田管道的结垢问题已经严重影响到油田的正常生产运行,超声波除垢技术作为一种新型物理除垢技术越来越受到重视。为了深入研究超声波对油田管道除垢的效果,设计了一套超声波除垢装置,分别进行了20、28、68、120 kHz四种频率下的超声波除垢模拟实验。针对碳酸钙垢,超声波频率为28 kHz时除垢效果最佳；超声波作用时间为5 min时除垢效果和经济效益最佳,垢质晶体形成能力较弱；超声波作用周期为12 h时,除垢能力较强。通过对碳酸钙、硫酸钙、硫酸钡、硫酸锶等四种常见的无机垢进行超声波除垢实验并对比,发现超声波对于硫酸钙垢的除垢效果最好。Scale has seriously impacted the normal operation of oil field. Ultrasonic treatment, as a new physical descaling technology, is getting more attention. To ascertain that ultrasonic treatment has effect on pipeline's anti-scaling, a set of ultrasonic descaling device was designed to experiment at different frequency of 20kHz, 28kHz, 68kHz, 120kHz respectively. For calcium carbonate, it was found that anti-scale effect was best under frequency of 28kHz; best descaling and economical benefit can be got when ultrasonic lasted for 5 minutes,with weaker ability of form crystals; the anti-scale ability is stronger at the ultrasonic action cycle of 12 hours. According to comparison for the results of ultrasonic scaling experiment for four salt scales, namely calcium carbonate, calcium sulfate, barium sulfate, and strontium sulfate, it is found that ultrasonic treatment has the best descaling effect on calcium sulfate.
