目前根据清管器功能大致分四类，有清扫型清管器、隔离型清管器、检测型清管器和管道维护型清管器。介绍了不同功能清管器各自的工作原理和特点，并研究分析了清管器未来的发展趋势，以及输送不同流体介质的管道包括原油管道、天然气管道和多相流体管道的清管作业特点，最后简要介绍了清管器清管周期的确定方法和清管流程。

Currently pigs can be broadly divided into four categories according to their specific functions, including the sweeping pig, the isolated pig, the detective pig and the pipeline maintenance pig. In this paper, their working principles and their working features were described,and their future development trends were analyzed. Different pigging characteristics of crude oil pipelines, gas pipelines and multiphase fluid pipelines were discussed. In the end, some methods to determine pigging cycles were introduced as well as the pigging processes.
