Abstract
The invention relates to a process for improving the characteristics of a fluid and in particular of a cement slurry for the cementing of wells, particularly of oil wells, wherein it consists in applying to this fluid an energy of between 4.8 and 6.3 kJ/kg, by incorporating adapted pressure drops, in line, before the well head and at the outlet of a high-pressure pump, said pressure drops being substantially independent of the flowrate. The invention also relates to a device for carrying out this process.
Claims7
Apparatus for homogenizing abrasive fluid comprising means for applying to said fluid an energy between 4.8 and 6.3 kJ/kg including a high pressure pump having at least one annular restriction, in line, at an outlet of said pump and mixing means in said one annular restriction whereby a pressure drop through said at least one annular restriction is substantially independent of flow rate.
