Definitions

  • This Invention Patent application covers a fluids injection flow control device for use in oil wells, designed to maintain an established range in the injection rate within a given layer between two packers, corresponding to the puncture zone of an injection well, causing a controlled pressure drop of the derived flow to said sector without damaging the molecule of the viscous fluid;
  • said device which is axially coupled to a tubing string, consists of a variety of modules formed by an upper coil support onto which a primary coil is helically wound, initially connected to the pipe through which the fluid runs, causing a certain load drop in an initial control component known as a side-pocket mandrel, which consists of two main parts namely the tubing string that allows for axial tubing continuity and the pocket in which a short or long flow direction vane is selectively installed that determines the outflow towards the unit by way of a transverse opening or its passage to the next module's corresponding coil through transition tubing.
  • the implementation of the device for each layer embodies an upper module provided with a pipeline
  • the device that enables Q injection flow rate control, responds to the concept that there are no fluid sources or basins within the control volume and that, pursuant to the Law of Conservation of Matter, the inflow of the bypass tube from the tubing is equal to the outflow, where the p1 pressure of said tube is in direct relation to the unit's p2 pressure.
  • certain geometrical parameters can be acted on, that is the tube's inner diameter D (technically complex), or the length L of said tube, which is achieved through the modelling of the coils and their coupling and decoupling to successive modules, with the consequent respective increase or decline in load loss.
  • D the inner diameter
  • L the length of said tube
  • the device in question is used for controlling the injection flow of viscous fluids, generally polymer chain based, in a specific layer of an oil injection well causing a controlled load loss without affecting its rheological properties.
  • the primary aim of this patent application is to offer a device capable of maintaining the injection flow rate within a predetermined range in a given layer of an injection well, by producing a controlled pressure drop by virtue of the fact that the different coil length combinations developed as well as their inner diameter enable different flow ratios vs. pressure differentials.
