Numerical simulation on the migration and deposition of micron-sized sand particles in the helical tube section during hydrate production tests

Abstract In the exploitation process of offshore natural gas hydrate (“hydrate” for short), it is necessary to take into consideration the wear of wellbore equipment caused by micron-sized sand particles after their breaking through the sand control facility of the wellbore. At present, however, there is no literature on the migration, deposition and blockage of micron-sized sand particles (
