致密气田集输管道积液规律分析研究

Analysis and Research on Liquid Accumulation Patterns in Tight Gas Field Gathering and Transportation Pipelines

摘要: 为了研究致密气田集输管道积液规律，利用多相流模拟软件OLGA建立管道积液模型，计算分析该管道沿程各项状态参数(包括压力、温度、管内流速、流体流型、持液率、总积液量)随生产运行时间的变化情况，从模拟运行168小时的结果来看，管内各项状态数据变化甚微，说明在本文设计参数条件下管道运行状态相对稳定。

Abstract: In order to study the liquid accumulation rules of tight gas field gathering and transportation pipelines, the multiphase flow simulation software OLGA was used to establish a pipeline liquid accumulation model, and calculate and analyze various state parameters along the pipeline (in-cluding pressure, temperature, flow velocity in the pipe, and fluid flow pattern). Liquid holding rate, total liquid volume changes with production operation time. Judging from the results of 168 hours of simulated operation, the status data in the pipe changed very little, indicating that the pipeline operating status is relatively stable under the design parameters of this article.
