摘　　要：清管作业是长输管道投产前或运行中的一项重要工作,可保证管道的正常运行和输送效率。对于不同类型的管道,要达到较好的清管目的,必须合理选用清管器和清管技术。通过对清管器类型、清管方法、清管器进管道之前做的准备工作以及清管过程中可能遇到的故障进行分析,并通过清管技术应用的成功实例,为不同类型的长输管道投运、在线清管提供指导和参考。Pigging operation is an important task for long-distance pipeline before or during normal operation.It can ensure the normal operation of the pipeline and transportation efficiency.To achieve a better pigging effect,it must select reasonable kinds of pigging and pigging technology for different types of pipelines.It analyses the type of pigging pig cleaning technology for pipeline that should be adopted first in the preparatory work before the pig is moved into the long-distance pipeline,and analyzes the possible trouble during the pigging cleaning process systemically through the long-distance pipelines of oil,gas or two-phase flow.The examples that the pig cleaning technology has been applied successfully will provide methods and strategies and references for operation and pigging online of different types of long-distance pipelines.
