| titleOfInvention | Water stoppage control agent and muddy water stabilizing liquid for drilling using the same |
| abstract | PROBLEM TO BE SOLVED: To provide a viscosity adjusting action and a water stoppage improving action for a clay such as pentonite and / or a water-clay suspension composed of silt, earth and sand, and to improve their performance by pH. Provided is an adjustable water-stopping agent and a muddy water stabilizing liquid for drilling using the same. SOLUTION: Carboxyl group-containing monomer 20 to 80 parts by weight, (meth) Acrylic ester-based monomer 10 to 70 parts by weight, other copolymerizable monomer 0 to 10 parts by weight obtained by emulsion copolymerization, and from an alkali thickening emulsion having a specific viscosity developing property and water stopping properties depending on pH And a muddy water stabilizing liquid for drilling containing the same. |
