Oil-well slurry |
| abstract |
The invention relates to the oil and gas industry. The goal is to increase operational sv-in tampon composition. It contains (parts by weight) chloroprene rubber latex based on either homopolymer or copolymer of chloroprene with methacrylic acid containing not less than 98 wt.% Insoluble polymer 100; bentonite 20-30; ethoxylated phenol with degree of ethoxylation from 10 to 12 2.0-2.08: ammonium sulfate 4.0-4.5, water 304-348. The ratio between the content of ethoxylated phenol and ammonium sulfate is chosen in the range (1: 2) - (1: 2.25). 1 tab. |
