一种并联海管集输系统段塞接收与调控分析

Slug Receiving and Control Analysis for a Kind of Parallel Subsea Pipeline Gathering System

针对海洋油气生产中常见的一种海管并联集输系统,提出了段塞缓冲体积的定义和具体计算方法,从原理上分析了调控该海管集输系统段塞接收的方法。通过实际案例,对该海管集输系统在各个操作工况运行时的平台段塞接收能力进行了评估。针对平台段塞流捕集器无法正常缓冲集输系统段塞体积的情况,给出了多种调控方法,并阐述了最优方案。

According to a kind of parallel subsea pipeline gathering system in subsea oil and gas production, the definition and calculation method of slug volume are proposed. The method of slug receiving control is analyzed form the principle. Through the actual case, the slug receiving ability of the pipeline gathering system under each operating condition is evaluated. Aim to the situation that slug receiving vessel cannot buffer slug volume of gathering system, some control methods are proposed and the best plan is elaborated.
