Abstract

FIELD: oil and gas production. SUBSTANCE: composition containing bentonite, soda, and carboxymetylcellulose is supplemented with dolomite, water, and plasticizer in the following way: bentonite powder is added into water softened with soda, resultant mixture is agitated, whereupon dolomite powder, plasticizer, and carboxymetylcellulose are added. Utilization of dolomite allows creating colloid solutions with low concentration of bentonite clays. EFFECT: prolonged stability of solution and reduced cost with retaining performance characteristics.

Изобретение позволяет получать стабильный во времени, экологически чистый, недорогой раствор с относительно высоким утяжелением, совместимый со всеми поверхностно-активными веществами. Это достигается тем, что в состав, содержащий бентонит, соду и карбоксилметилцеллюлозу, дополнительно вводят доломит, воду и пластификатор. В воду, смягченную содой, добавляют бентонитовый порошок, перемешивают, а затем вводят порошок доломита, пластификатор и карбоксиметилцеллюлозу. Применение доломита в растворе позволяет создавать коллоидные растворы при значительной экономии бентонитовых глин.EFFECT: invention makes it possible to obtain a time-stable, environmentally friendly, inexpensive solution with a relatively high weighting, compatible with all surfactants. This is achieved by the fact that dolomite, water and a plasticizer are additionally added to the composition containing bentonite, soda and carboxyl methyl cellulose. Bentonite powder is added to soda-softened water, mixed, and then dolomite powder, plasticizer and carboxymethyl cellulose are added. The use of dolomite in solution allows you to create colloidal solutions with significant savings of bentonite clays.
