FIELD: chemistry.
SUBSTANCE: invention relates to oil extraction industry and can be used in processing water-based drilling fluid. In the method of processing drilling fluid, the drilling fluid is mixed with an additive in amount of the additive of 0.3-0.6 % of the volume of the drilling fluid continuously while circulating the drilling fluid with a jet into the stream of drilling fluid or through a measuring connection pipe on the suction line of a drill pump in a pumping unit. The additive used is a mixture of purified spent oil and Sinol EM emulsifying agent in ratio of 55-65 and 35-45% respectively.
EFFECT: design of an efficient method of processing drilling fluid.
