摘要： A system and method of wellbore operations that uses an eductor unit for introducing additives into a moving fluid stream to form a mixture. The mixture is used as a completion drilling fluid for drilling through plugs installed in a wellbore. Example additives include polymers, such as friction reducers, viscosifiers, potassium chloride, polysaccharide, polyacrylamide, biocides, lubricants, long chain polymer molecules, and the like. The fluid is primarily fresh water and/or brine water, and acts as a motive fluid in the eductor unit for drawing the additive into the eductor unit. Forming the mixture in the eductor unit which is injected into the wellbore.

摘要： A mixing device has an elongate shell, an inlet, an outlet and at least one shear orifice between the inlet and the outlet. A hydration passage is located between the shear orifice and the outlet. The hydration passage has a flow area greater than a total shear flow area of the shear orifice, greater than an inlet flow area of the inlet and greater than an outlet flow area of the outlet. During operation, a polymer is mixed in a fluid flow flowing to the intake of a positive displacement pump, which pumps the fluid through the mixing device and into an injection conduit leading into a well. The shear orifice produces high shear separation of molecules of the polymer. The hydration passage causes hydration under pressure of the various polymer molecules in addition to blending the various chemicals and/or gases with other components of the fluid flow stream.
