| titleOfInvention | How to improve the wall-forming properties of drilling mud |
| abstract | (57) [Summary] [Purpose] To effectively regenerate degraded mud without disposing of it. In the method for improving the wall-forming properties of a drilling mud according to the present invention, an unsaturated carboxylic acid and / or a salt thereof (a) is added to degraded mud generated by a mud drilling method such as an underground continuous wall method or a mud shield method. And a monoester (b) of the unsaturated carboxylic acid (b1) and the hydroxyl group-containing compound (b2) represented by R (OA) n OH as constituent units (x) as essential components. Add a mud film forming agent for drilling mud. Here, R is hydrogen or a hydrocarbon group having 1 to 12 carbon atoms, A is an alkylene group having 2 to 4 carbon atoms, and n is 1 to Indicates an integer of 100. |
