Drilling mud

Abstract

A drilling mud is proposed, which contains a dispersion medium, a dispersion phase, for instance, clay, a stabilizer reagent, for instance, carboxymethylcellulose and a weighter. In order to reduce the viscosity and to increase the stability of the mud it contains as the dispersion medium a 75% aqueous solution of the L-7 reagent. To increase the salt resistance of the mud, it additionally contains sodium chloride in a volume of 4.04.5 percent by weight, and to regulate the alkalinity, it additionally contains sodium hydroxide in a volume of 1.1 to 1.3 percent by weight.
