Abstract

Abstract: The sealing of casing thread is a key factor affecting the safety of UGS (Under Gas Storage) well for periodic highspeed injection and production operation, so the integrity of sealing of gas storage well is extremely important. It is necessary to focus on the influence of gas storage well injection and production process on the sealing property of the string, especially the variation law of the special thread joint sealing structure performance of the UGS string caused by the alternating load in the process of circulating injection and production. Based on the theory of finite element method, combined with the actual working condition of the UGS well and field data of a special thread joint used in a UGS well in northern China, a special thread joint finite element calculation model is established and the cycle injection-production condition, temperature, injection-production pressure, axial load and pitting of the effects of the casing thread seal UGS is studied. The results show that the temperature has little effect on the structural integrity and sealing integrity of the casing thread joint, but the injection-production pressure, axial load, and pitting have a great effect on it, which should be controlled at a low value. This study can provide a reference for sealing failure determination and pipe string design of gas storage wells.

Key words: under gas storage well, special thread joint, casing sealing, high-speed injection-production, alternate load
