    • The present invention relates to a device for transforming at least two fluid flows into a number of minor fluid flows and mixing said minor flows. Said device comprises at least two hollow sectional cylinder or cone bodies which lie one on top of each other in a coaxial manner forming at least two annular spaces, a plate (50) covering one end of said bodies perpendicular to the bodies axis having inlets through which said fluidflows (25, 20) are fed to said spaces and a distributor plate (11) located at the opposite end of said bodies and optionally at least one distributor plate located within said bodies. All said distributor plates are perpendicular to the bodies axis, where said distributor plates cover the entire cross-sectional area of said spaces and said distributor plates have a number of channels (45) and holes (40) through which said fluid flows are fed from said spaces to a mixing zone located adjacent to each of said disks. Furthermore, the present invention relates to a method for transforming at least two fluid flows into a number of minor fluid flows and mixing said minor flows. Said method is performed in said device where said fluidflows are fed through said inlets into said spaces towards said distributor plate(s) and further through said holes and channels into said mixing zone where a homogeneous mixing between said minor flows occurs. The present invention also relates to a use of said device and method.

    • Assembly for pressure control when drilling underground to locate or produce hydrocarbons; whereby the drilling is done by means of a drill string with fluid circulation down through the drill string and up through an annulus between tlie drill string and the open hole or casing, as the underground in the open hole may comprise one or both of: areas with formation strength which is unable to withstand the pressure from the fluid circulation without fracturing and areas with formation pressure which cannot be combined with each other or the fluid circulation pressure without the fluid unintentionally leaking in or out from the above-mentioned areas. The assembly is distinguished in that onto the drill string a bottomhole assembly is fitted, comprising: a reversible and expandable packer fitted near to the lower end of the drill string to seal the annulus, controllable from the surface a measuring device for measuring the pressure inside the annulus both above and below the packer, with means to simultaneously transfer the data to the surface, a circulation valve fitted above the packer and controllable from the surface in order to open or close off the communication of fluids between the inside of the drill string and the annulus, a control valve (closing valve) fitted below the circulation valve and controllable from the surface, to open and close off the communication of fluids through the drill string, and a connecting sub located above the packer and controllable from the surface for connecting and un-connecting the drill string.
