摘      要：To meet the requirements of marine natural gas hydrate exploitation,it is necessary to improve the penetration of completion sand control string in the large curvature *** this study,large curvature test wells were selected to carry out the running test of sand control string with pre-packed ***,the running simulation was performed by using the Landmark *** results show that the sand control packer and screen can be run smoothly in the wellbore with a dogleg angle of more than 20°/30 m and keep the structure ***,the comprehensive friction coefficient is 0.4,under which and the simulation shows that the sand control string for hydrate exploitation can be run *** findings have important guiding significance for running the completion sand control string in natural gas hydrate exploitation.
