Simulation Analysis of Erosion Wear Induced by Hydraulic Fracturing Fluid in Cross-pipe

  • 摘要: 在页岩气压裂开采过程中,为了提高压裂效率,部分井场在地面采用一种新型的高压管汇快接装置。针对该装置中四通管处的冲蚀磨损问题,基于DPM冲蚀预测模型,利用FLUENT软件研究水力压裂下快接管汇装置的四通部位的冲蚀磨损规律。结果表明,冲蚀集中面位于相贯线及其附近的管壁上;质量流不变的情况下,随着粒度的增大,相贯线上最大冲蚀率呈指数式降低,管壁上最大冲蚀率先增大后减小;质量流不变的情况下,随着黏度的增大,最大冲蚀磨损量增大,且随着粒径的增大,其变化规律由对数型向指数型过渡。
