Analysis of Serious Deformation of Cavitation Tubing in Salt Cavern Gas Storage in Jianghan Oilfield

Abstract Jianghan Oilfield salt cavern gas storage is characterized by depth, high temperature and pressure. At present, the main problem of that in process cavitation, frequent bending deformation at end cavitation tubing string leads to difficulty operating string, which extends period affects production storage. The was counted, causes were analyzed from aspects layer geological characteristics, mechanics, fluid etc. It concluded injection rate higher than critical liquid carrying flow rate, leading instability deformation, provided theoretical reference for construction
