140 MPa压裂管汇四通管道冲蚀模拟

Erosion Simulation of 140 MPa Fracturing Manifold Four-Way Pipeline

摘要: 随着页岩气开采难度的增加，为了提高效率，部分厂商设计了140 MPa高低压管汇撬，由于压裂液的冲蚀以及管道工作处于高压环境，高压管汇极易发生冲蚀磨损情况。针对140 MPa压力下四通管道的冲蚀磨损情况，根据RNGκ-ε湍流模型和DPM冲蚀模型，利用FLUENT仿真软件分析水力压裂情况下的管汇撬四通管道的冲蚀磨损规律。分析结果发现，冲蚀磨损面主要发生在四通管道交汇处及附近管壁上。

Abstract: With the increasing difficulty of shale gas extraction, in order to improve efficiency, some manufacturers have designed 140 MPa high and low pressure manifold levers. Due to the erosion of fracturing fluid and high-pressure environment, the high-pressure manifold is prone to erosion and wear. Based on the turbulence model and DPM erosion model, FLUENT simulation software was used to analyze the erosion and wear patterns of the four-way pipeline under hydraulic fracturing pressure of 140 MPa. The analysis results show that erosion and wear surfaces mainly occur at the intersection of four-way pipelines and near the pipe walls.
