摘　　要：结合榆3×储气库的注采工况,构建了气固冲蚀预测模型,研究了采气量、采气压力、颗粒属性等生产参数对冲蚀速率的影响规律,针对N80油管分析了发生不同程度冲蚀风险的极限生产工况。结果表明:在榆3×储气库预设采气指标范围内,最大冲蚀速率随采气量的增大而增大;采气压力的增加会一定程度上降低管柱的冲蚀程度;冲蚀程度随出砂量的增加呈现线性增加趋势,颗粒直径的增大会导致冲蚀速率的增大,而颗粒球度的减小会导致冲蚀速率的增大。基于预测模型,建立了N80油管的临界生产参数图版,以实现基于现场易获取参数的冲蚀风险评估。A gas solid erosion prediction model was established based on the injection production conditions of Yu 3×gas storage.The effects of production parameters such as gas production flux,gas production pressure and particle properties on the maximum erosion rate were studied,the critical production conditions were analyzed for N80 oil pipe with different degrees of erosion risk.The results show that the maximum erosion rate increased with the increase of gas production flux within the preset gas production index range of Yu 3×gas storage,while the increase of gas production pressure reduced the erosion degree of the pipe string to a certain extent.The degree of erosion increased linearly with the increase of sand production flux.The increase of particle diameter led to the increase of erosion rate,and the decrease of particle sphericity led to the increase of erosion rate.Based on the prediction model,the critical production parameter chart of N80 oil pipe was established for the erosion risk assessment based on easily available parameters on site.
