| titleOfInvention | Procedure for process treatment of underground formations by means of modifying gel-forming agents (versions) |
| abstract | FIELD: gas and oil production. ^ SUBSTANCE: procedure for treatment of underground formation with processing thickened liquid consists in: mixing water, carbonyl containing first compound and amine containing second compound. The carbonyl containing first compound contains at least one carbonyl group and corresponds to either gel forming agent or to modifying agent. The amine containing second compound contains at least one amine group and corresponds to a gel forming agent when the carbonyl containing first compound is a modifying agent, and to a modifying agent when the carbonyl containing first compound corresponds to the gel forming agent. The gel forming agent corresponds to at least one following compounds: polysaccharide, natural polymer, bio-polymer or synthetic polymer and the modifying agent corresponds to at least one of the following compounds: halogenide, epoxide, polysaccharide, natural polymer, bio-polymer or synthetic polymer. Further, the procedure consists in interaction between at least one carbonyl group of the first compound and at least one amine group of the second compound with formation of modifying bond and production of the modified gel forming agent and in introduction or thickened liquid into a section of an underground formation. The procedure for formation of break of a section of the underground formation by means of processing thickened liquid includes the above said stages. Also, processing thickened liquid is pumped into a section of the underground formation under pressure sufficient for creation or expansion of at least one break in it. ^ EFFECT: production of modified thickened agents. ^ 16 cl |
