| titleOfInvention | Method for preparing lignosulfonate reagent for drilling muds |
| abstract | 1. A method of producing a lignosulfonate reagent for drilling solutions, including mixing sulphite-alcohol stillage or sulphite liquor with a compound of hexavalent chromium, characterized in that, in order to increase the structure-forming properties of the reagent and its ability to reduce the flow of flurry molds. , a solid filler is pre-introduced into the sulfite-alcohol bard or sulfite liquor. O, 5-5.0% aqueous solution of liquid glass in a weight ratio of 1: 3-1: 5. 3 2. The method according to p. 1, difference. Yusch and with the fact that as a solid filler use finely divided asbestos ktti finely divided cellulose., or clay, or 2 chalk. |
