BATH COMPOSITION FOR FREEING STUCK PIPE COLUMNS

摘要

FIELD: chemistry. ^ SUBSTANCE: invention relates to oil-and-gas industry and can be used as composition of a liquid bath for freeing stuck pipe columns in difficult mining and geological conditions. The bath composition for freeing pipe columns contains, wt %: glycerin - 10 to 15; hydroxylamine chloride - 20 to 25; water - the rest. ^ EFFECT: increased efficiency of freeing stuck pipe columns due to increase in degree of breakdown of the coagulation structure of clay particles in the well through improved dispersant properties of the composition. ^ 1 tbl, 1 dwg
