THERMOTROPIC GEL-FORMING COMPOSITION

机译:热凝胶形成组合物

摘要

FIELD: chemistry.SUBSTANCE: invention relates to oil-extracting industry, in particular to dry thermotropic compositions, water solutions of which form gel due to formation temperature after introduction into oil pool. Thermotropic gel-forming composition includes aluminium chloroxohydrate with hydrogen pH index of its 1% water solution not lower than 3.5, carbamide, polyethyleneoxide and additionally contains talc with the following component ratio, wt %: aluminium hydroxochlorate- 25-40, carbamide - 58-73.9, polyethyleneoxide - 0.1-0.2, talc - 1-4.EFFECT: increased efficiency of composition due to stabilisation of flowability in storage and transportation, simplification of technological process of application, also when composition is dosed into water flow through ejector while pumping into well.1 tbl
