国内外油气管道清管技术的现状和发展趋势

The Current Situation and Development Trend of Oil and Gas Pipeline Cleaning Technology at Home and Abroad

结合目前国内油气管道清管技术中存在的清管效果不理想,缺乏统一的标准规范等问题,介绍了国内外清管器的类型、选型依据、清管质量的控制、清管周期、清管器速度的控制与预测、清管器的跟踪定位、清管作业安全区域的确定等相关技术及国外的先进经验,对提高国内清管技术水平有重要意义。

According to the current situation of oil and gas pipeline cleaning technology at home and abroad,the type of pipeline pig,the basis for type selection,quality control of pigging operation,the pigging cycle,control and prediction of pig speed,pig tracking and location,and determination of safety area of pigging operation,as well as the foreign advanced experience of pipeline cleaning technology are introduced. Some questions existing in the domestic pigging technology are pointed out,such as the unsatisfied cleaning effect and the lack of unified standards,providing a reference for improving the level of domes-tic pipe cleaning technology.
