摘要：

传统清管器在天然气凝析液管道清管作业中存在清管器运行速度过快,清管段塞大等诸多缺陷.为解决传统清管器的这一系列问题,射流清管技术得到了发展.为了分析射流清管器设计及应用过程中需要考虑的因素,利用OLGA 7.2模拟软件建立了海底管道清管模型,对射流清管器旁通率,管道管径,气液比,清管器质量等因素进行了分析,为射流清管器的设计及其应用提供借鉴.

Abstract:

There exist many problems such as high pigging velocity and long pigging slug in the pigging process in natural gas liquid pipelines by using traditional pig. In order to solve these problems, bypass pigging technology has been developed. To analyze relevant factors in the design and application of bypass pig, a subsea pipeline pigging model is built by using OLGA software (version 7.2) and the factors including bypass ratio of the bypass pig, pipe diameter, gas liquid ratio, pig weight etc. have been analyzed, which can provide reference for the design and application of bypass pig.

Key words: subsea oil and gas pipeline, bypass pig, bypass ratio, pigging, influence factor
