- 摘要:
- 硫沉积问题一直是高含硫气田开发中的难题，研究的焦点多集中在气藏地层和井筒中，而集输系统中硫沉积问题近年来才逐渐引起重视。集输系统中管道硫沉积研究所遇到的“瓶颈”是硫沉积的机理尚不清楚，因而，目前对于管道硫沉积的防控技术主要是针对系统中已沉积的元素硫所采取的物理化学治理，不能有效解决湿气集输模式下集输系统的硫沉积问题。通过总结归纳集输系统内硫沉积的研究现状，提出了新发现的基于高含硫气田集输管道呈现的环壁等厚度硫沉积特征的机理和今后研究的发展方向。
Sulfur deposition is always an important and difficult problem in development process of gas reservoirs with high H2S content.Most of past researches were focused on gas reservoir formation and bore holes, and elemental sulphur deposition in natural gas gathering system has been paid attention to gradually in recent years. Investigation on sulphur deposition of large-scale space focused on sulfur deposition in pipelines has encountered such bottleneck problem as unclear mechanism of sulfur deposition. Therefore, current physical and chemical methods are used to prevent and control the sulfur deposition, which are unable to effectively solve gathering and transportation system sulphur deposition problem existing in wet gas gathering and transmission conditions. Summarized is the research status of sulfur deposition in gathering and transportation systems, analyzed are characteristics of equivalent thickness sulfur deposition layer new discovered in high sour gas field gathering and transportation system and put forward is the development direction of future research.
