A drag reducing agent for a water-in-oil emulsion is provided. The agent comprises a water-soluble powder component and a fat-soluble powder component. The weight ratio of the water-soluble powder component to the fat-soluble powder component in the agent ranges from 1:2 to 1:4. The water-soluble powder component is made of polyacrylamide, and the fat-soluble powder component is made of polyacrylate. By using the powder form of the water-soluble and fat-soluble components, it is possible to mix them into the water-in-oil emulsion, which may significantly reduce the hydrodynamic drag of the water-in-oil emulsion. In a preferred embodiment, the fat-soluble powder component is made of polyacrylate latex. In an optional embodiment, the agent may further comprise an anti-agglomeration agent to prevent the fat-soluble and water-soluble powder components from agglomerating with each other.
