【摘要】 在采油过程中常出现因油砂堵塞输油管道而进行停工检修的问题，除砂检修过程大大降低了采油效率、增加了维修成本。本研究设计的并联式双管自动除砂输油管道装置，通过滤网自动除砂系统与并联结构相结合的方式，可实时监测管道堵塞情况并自动清洁堵塞管道，两根管道交替使用可实现“除砂检修不停工”，可以大大提高采油效率。管道可根据实际情况设计尺寸，能够应用于各种油田场景，具有较好的研究价值和应用性。更多还原

【Abstract】 In the process of oil recovery, there is often a problem of stoppage and maintenance due to oil sand blockage in the pipeline, and the process of desanding and maintenance greatly reduces the oil recovery efficiency and increases the maintenance cost. In this research, the parallel double-pipe automatic sand removal pipeline device can monitor the blockage of the pipeline in real time and clean the blocked pipeline automatically by combining the automatic sand removal system with the parallel structure, and the two pipelines can be used alternately to achieve“sand removal and maintenance without stopping work”. The pipeline can be designed according to the actual situation, and can be applied to various oilfield scenarios,which has good research value and applicability.更多还原
