- 摘要:
随着海洋油气开发规模的扩大，深水长输油气管道的维护变得愈发重要，水下自动清管装置与直板式清管器的应用，既能有效清理管壁，又可提高清管及时性并降低生产成本。基于Abaqus 2023软件，采用耦合欧拉-拉格朗日方法构建水下自动发球过程流固耦合仿真模型。通过调整清管器密封盘的过盈量及其盘数并分别进行仿真，结合摩擦力、速度等结果，分析这些参数对清管器运行效果的影响。研究发现，不同过盈量的直板清管器所受摩擦力变化趋势基本一致，过盈量越大，摩擦力越大，且密封盘变形更稳定；过盈量过小则可能导致直板清管器与管道接触不充分，密封盘形变量小且易发生不规则形变，进而引发速度波动；密封盘数量越多，摩擦力越大，其固定清管器的能力与密封能力越优。研究成果可为水下自动清管装置顺利发射清管器提供理论依据和参考。
With the expansion of the scale of marine oil and gas development, the maintenance of deep-water long-distance oil and gas pipelines becomes increasingly important. The application of underwater automatic pigging devices and plug-type pigs can not only effectively clean the pipe wall, but also improve the timeliness of pigging and reduce production costs. Based on Abaqus 2023, this paper established a fluid-solid coupling simulation model of the underwater automatic pig launching process by using the coupled EulerianLagrangian method. By modifying the interference of the pig seal disk and the number of seal disks and simulating them separately, combined with the results of friction force and velocity, the paper analyzed the influences of these parameters on the running effect of the pigs. It is found that the trend of friction force changes of the plug-type pigs with different interference is basically the same. The greater the interference, the greater the friction force and the more stable the deformation of the seal disk. An interference that is too small may lead to insufficient contact between the plug-type pig and the pipeline. The seal disk has small deformation and is prone to irregular deformation, resulting in speed fluctuations. The larger the number of seal disks, the greater the friction force and the better the ability to fix the pig and seal. The research results can provide theoretical basis and reference for the smooth pig launching by underwater automatic pigging devices.
