原油管道输送过程中会发生结蜡现象,造成流通截面逐渐变小,输送能力下降,运行成本增大,因此对管道进行清管作业,合理确定清管周期,对保证管道安全平稳生产,降低生产成本非常有利。本文通过对长输管道运行现状的研究,给出了适合长输管道的清蜡方法和清管流程,以此指导现场实际运行有效的提高了管道输送能力,降低了运行压力,保障了管道的安全运行,节约了生产成本。
Waxing phenomenon occurs during the transportation of crude oil pipelines, resulting in a gradual decrease of flow cross section, a decrease of transportation capacity and an increase of operating costs. Therefore, pigging operations on pipelines and rational pigging cycle are ensured to ensure safe and steady production of pipelines and reduce production The cost is very favorable. In this paper, through the study of the status quo of long-distance pipeline operation, the method of wax removal and pipe cleaning suitable for long-distance pipeline are given, which can guide the actual operation of the site to effectively improve the pipeline transportation capacity, reduce the operating pressure and ensure the pipeline Safe operation, saving production costs.
