FIELD: mining.
SUBSTANCE: invention relates to well drilling, namely to flush fluids used for cleaning of wells drilled using hydrocarbon based mud. Flush water based fluid contains, wt%: sodium tripolyphosphate 3-4, butyl glycol 10-15, water - the rest.
EFFECT: technical result is high cleaning efficiency of flush fluid and, consequently, improved quality of adhesion of cement stone to rocks and casing.
