Erosion caused by solid particles is one of the important reasons for the failure of shale gas gathering pipelines. However, the erosion laws of right-angle pipe and blind tee were rarely compared in previous studies, and the parameter settings almost did not meet the actual requirements of shale gas exploitation. The aim of this paper is to study the erosion laws of 90° elbow, right-angle pipe and blind tee based on the production parameters of a gas field. CFD-DPM approach integrates the Mixture model, the Discrete Phase Model, and an erosion model is employed to predict solid particle erosion in gas-liquid two-phase flow in the shale gas field. The results show that the maximum erosion rate of pipe wall increases exponentially with the fluid velocity. With the development of mining, the lower the free water content, the more serious the pipe wall erosion. In addition, under the same working conditions, the blind tee is relatively erosion-resistant compared with 90° elbow and right-angle pipe. The shale gas gathering and transmission system can use blind tees to connect pipes and limit fluid velocity, so as to prolong service life and ensure flow safety. |
