Research on the erosion simulation of multi-layer filling sand control tools
Due to strong pressure fluctuations inside equipment in the process of oil and gas production and operation,it is prone to undergo erosion and wear.Once puncture and fracture occur,it is very likely to cause casualties and serious consequences.Based on investigation and analysis of erosion damage to sand control tools,the patterns of erosion damage in tubular pile system of multi-layer filling and fracturing construction was studied through erosion simulation experiments which under different condi-tions of fluid flow rates,sand carrying ratios,solid particle sizes and continuous phase viscosity.The findings showed that the main factor affecting erosion of filling pipe hole is output volume of liquid-solid multiphase flow.In addition,there might be in-stances of particle deposition when particle concentration is high.At the same time,considering tool structural parameters and erosion flow parameters,a predictive model for erosion damage of sand control tools was developed.The model was utilized to cal-culate erosion rate distribution and describe main erosion characteristics.Finally,based on simulation test results,structural op-timization suggestions were proposed for existing tools,which may improve overall performance and reliability of tubular pile and provide reference for subsequent construction of erosion prediction model for sand control tools.
