| abstract | The invention relates to drilling; wells in the exploration industry and the oil industry and is designed to test them. The goal is to improve the technological properties of the solution by reducing its viscosity at 45- 90 ° C. The solution contains the following ingredients, wt%: polyacrylamide with a carboxyl group content of 0.5-1.9% by weight 0.14-0.20 ; alkali metal dichromate 0.14-0.20; hyposulfite O, 11-0.15; ammonium oxalate 0.001-0.010, water the rest. The solution is prepared by gradually dissolving the ingredients in the solution in water. The use of the mortar reduces the time and cost involved in fighting the complications associated with sticking the drill string or losing the technological properties of the drilling mud. 1 tabLo (L |
