Optimization of the nozzles' structure in gas well

Abstract

Abstract. High-speed gas in wellhead throttling nozzle carry condensate water and sand, which cause serious erosion to nozzle. Erosion rate with the velocity generally show an exponential growth, the higher the gas velocity inside the nozzle, the more serious erosion. This paper mainly analyze gas fluid flow in nozzle and propose optimization project of nozzle structure. This project try to decrease fluid velocity turbulence structure and erosion under pressure drop and temperature are satisfied.
