Patent number: 7794135Abstract: Disclosed are apparatus and methods for preparing wellbore viscous treatment gels from dry polymer and water. The apparatus includes an eductor which slurries dry polymer with water, at least two input tubes, wherein one input tube is connected with the eductor, and another to a water source. The apparatus also includes a mixing chimney connected to the input tubes. The mixing chimney includes a lower input section with inlets connected to the input tubes wherein a jet of metered dilution water is applied at high pressure to the incoming polymer-water slurry stream. This mixture is then accelerated in a circular, and preferably upward, motion where it is sheared against the wall of a central section of the chimney, without the use of an impeller. The chimney further includes an output section that comprising holes circumferentially located, through which the mixture passes from the central section and into a hydration tank.Type: GrantFiled: October 7, 2005Date of Patent: September 14, 2010Assignee: Schlumberger Technology CorporationInventors: Ismail El Kholy, Gregoire Jacob, Jean-Louis Pessin

Publication number: 20090296516Abstract: The dynamic mixer for mixing components in different volumetric amounts comprises a rotor housing (25) in which a mixing rotor is arranged and which is closed on the inlet side by a cover (45) on which inlets for the components are arranged. The inlet (47) for the first component having the larger volumetric amount leads to an antechamber (32) that communicates with a following mixing chamber (36) by at least one passage (19). The mixing rotor (10) includes a distributor body (13) located in the antechamber for distributing the first component around the axis of rotation of the mixing rotor. The inlet (48) for the second component having the smaller volumetric amount leads to at least one inlet opening (54) located in the area of the passage to the mixing chamber transversally to the axis of rotation.Type: ApplicationFiled: October 3, 2006Publication date: December 3, 2009Applicant: Sulzer Mixpac AGInventor: Wilhelm A.

Patent number: 7575364Abstract: A cyclone type cylindrical body 10 having a part whose diameter decreases in the direction toward a lower opening from an upper opening is used, and liquid is made fall in the inside of the cylindrical body 10 while swirling and thereby accelerated to form a vortex flow. Fine particles are charged into the center of the vortex flow so as to be wrapped by the vortex flow, and thereby the both are mixed. By this characteristic, the fine particles do not contact with an inner wall of the cylindrical body, and therefore clogging does not occur in the cylindrical body. Moreover, the pressure around the center of the vortex flow becomes negative, and the fine particles are aspirated. Therefore, dust is hardly generated. Thus, a mixing apparatus of a small size that can slurry fine particles without much maintenance cost can be provided.Type: GrantFiled: February 26, 2004Date of Patent: August 18, 2009Assignee: Okutama Kogyo Co., Ltd.Inventors: Noboru Goto, Kouzi Sekine
