| 成果简介 | NOVELTY - Invention relates to breaker compositions for breaking down a filter cake of a non-aqueous drilling fluid during well completion and development. Breaker composition contains 17.0 wt.% sulphamic acid, 5.0-15.0 wt.% of mutual solvent, which is a solid phase dispersant – butyl cellosolve, 0.5-1.0 wt.% of nonionic surfactant, which is oxyethylated monoalkylphenol based on propylene trimers Neonol AF9-12, and fresh water – the rest. USE - Mining; chemistry. ADVANTAGE - Increased efficiency of destruction of filter cake and blocking emulsion formations in bottomhole formation zone. 1 cl, 6 tbl, 3 ex |
