Abstract:
Linear pressure reducer apparatus for regulating injection pressure of a water-soluble polymer solution in injection wellheads, in an enhanced oil recovery system, including modules connected in series to the main injection pipe and each consisting of tubes of identical diameter but variable length, the apparatus allows variations to be made to pressure drop by adjusting the length of the tube through which the solution flows by closing or opening modules, without substantial degradation to the viscosity of the solution during its passage through the module. Installation for enhanced oil recovery implementing the apparatus.
