摘要: 针对油气田水力压裂作业中高压管汇内弯头、阀门、三通等部件因高压携砂液冲蚀导致的穿孔及爆裂风险，本文自主设计并搭建液固两相流冲蚀试验装置，研究冲击角度、颗粒粒径和冲击速度对冲蚀率的影响，并基于实验数据采用最小二乘法构建冲蚀模型。利用该模型分析颗粒粒径、压裂液入口流量和颗粒质量流量对Y型三通管冲蚀率的影响，并优化其空间开角及倒圆半径。结果表明，Y型三通管的主要冲蚀区域集中在两支管与主管的相贯线壁面及主管前段。颗粒粒径对冲蚀率的影响呈先减小后增大趋势，350μm时最小；颗粒质量流量增加使冲蚀率线性上升；压裂液入口流量超过0.9 m3·min-1后，冲蚀率显著提高；空间开角增大加剧冲蚀，60°以上增长速率加快；设置20mm倒圆可降低冲蚀率35.8%。研究结果可为压裂管汇结构优化及关键冲蚀区域监测提供理论支持，以提升压裂作业的安全性和可靠性。

Abstract：Aiming at the risk of perforation and burst caused by erosion of high-pressure sand-carrying fluid in elbows, valves, tees and other components of high-pressure manifolds in hydraulic fracturing operations of oil and gas fields, this paper independently designs and builds a liquid-solid two-phase flow erosion test device to study the impact angle, particle size and impact velocity. The influence of erosion rate, and based on the experimental data, the least squares method is used to construct the erosion model. The model was used to analyze the effects of particle size, fracturing fluid inlet flow rate and particle mass flow rate on the erosion rate of Y-type tee, and to optimize its spatial opening angle and rounding radius. The results show that the main erosion areas of the Y-type tee are concentrated on the wall of the intersecting line between the two branches and the main pipe and the front section of the main pipe. The effect of particle size on erosion rate decreases first and then increases, and it is the smallest at 350 μm. The erosion rate increases linearly with the increase of particle mass flow rate. When the inlet flow rate of fracturing fluid exceeds 0.9 m3 · min-1, the erosion rate increases significantly. The increase of the space opening angle aggravates the erosion, and the growth rate above 60 ° accelerates. Setting 20 mm rounding can reduce the erosion rate by 35.8 %. The research results can provide theoretical support for the optimization of fracturing manifold structure and the monitoring of key erosion areas, so as to improve the safety and reliability of fracturing operation.
