Abstract

Efficient gas–liquid–solid pre-separation of oilfield recovery fluids is essential for downstream processing. Conventional feed systems fail to separate sand, suffer from high pressure drops, and operate with low efficiency. This study introduces a spiral multiphase pre-separator (SMPPS) and employs computational fluid dynamics (CFD) to examine flow distribution, separation mechanisms, and the effects of gas fraction, particle size, and viscosity on performance. Results show that the SMPPS stabilizes the flow field, suppresses turbulence, and maintains a pressure drop below 0.025 MPa. Performance boundaries are defined: at 35–40 % gas fraction, 0.2–0.3 mm particle size, and 1–3 mPa·s viscosity, gas and solid separation efficiencies exceed 91 % and 73 %. These findings provide both theoretical guidance and practical support for optimizing multiphase pre-separation and applying spiral separators in oilfield operations.

气液固多相螺旋分离器用于油田采出液分离的性能研究

油田采出液的高效气液固预分离是后续处理的关键。传统的进给系统不能分离砂粒，承受高压降，并且效率低。本研究介绍了一种螺旋多相预分离器（SMPPS），并利用计算流体动力学（CFD）研究了气流分布、分离机制以及气体分数、粒度和粘度对分离性能的影响。结果表明，SMPPS稳定了流场，抑制了湍流，使压降保持在0.025 MPa以下。在35 ~ 40%气分、0.2 ~ 0.3 mm粒径、1 ~ 3 mPa·s粘度条件下，气固分离效率分别超过91%和73%。研究结果为优化多相预分离及螺旋分离器在油田中的应用提供了理论指导和实践支持。

期刊介绍： The Journal of Water Process Engineering aims to publish refereed, high-quality research papers with significant novelty and impact in all areas of the engineering of water and wastewater processing . Papers on advanced and novel treatment processes and technologies are particularly welcome. The Journal considers papers in areas such as nanotechnology and biotechnology applications in water, novel oxidation and separation processes, membrane processes (except those for desalination) , catalytic processes for the removal of water contaminants, sustainable processes, water reuse and recycling, water use and wastewater minimization, integrated/hybrid technology, process modeling of water treatment and novel treatment processes. Submissions on the subject of adsorbents, including standard measurements of adsorption kinetics and equilibrium will only be considered if there is a genuine case for novelty and contribution, for example highly novel, sustainable adsorbents and their use: papers on activated carbon-type materials derived from natural matter, or surfactant-modified clays and related minerals, would not fulfil this criterion. The Journal particularly welcomes contributions involving environmentally, economically and socially sustainable technology for water treatment, including those which are energy-efficient, with minimal or no chemical consumption, and capable of water recycling and reuse that minimizes the direct disposal of wastewater to the aquatic environment. Papers that describe novel ideas for solving issues related to water quality and availability are also welcome, as are those that show the transfer of techniques from other disciplines. The Journal will consider papers dealing with processes for various water matrices including drinking water (except desalination), domestic, urban and industrial wastewaters, in addition to their residues. It is expected that the journal will be of particular relevance to chemical and process engineers working in the field. The Journal welcomes Full Text papers, Short Communications, State-of-the-Art Reviews and Letters to Editors and Case Studies
