Definitions

  • This specification relates to a flow control system for a wellbore, and in particular to an advanced flow system including both autonomous and surface controlled such systems for control of the flow of fluids into a wellbore.
  • Wellbore production involves installing a production string, made of a plurality of production devices, inside a wellbore to allow the oil/ gas to flow from the reservoir/ formation to the surface through the production devices of the production string.
  • a production string made of a plurality of production devices
  • oil, gas or water either as a single phase or any combination of phases
  • the flow can occur in unpredictable or suboptimal manners.
  • a pressure or a rate of fluid flowing into the production string or a permeability at one part of the well could be significantly higher than the rate at another part of the well.
  • the oil-water ratios may change as a result of the changes in the bottom hole conditions such as differences between the average reservoir pressure and the flowing bottom hole pressure during production, in a phenomenon known as "coning".
  • Coning is a production problem in which gas or bottom water infiltrates the perforation zone in the near-wellbore area and reduces oil production. Coning only develops once the pressure forces drawing fluids toward the wellbore overcome the natural buoyancy forces that segregate gas and water from oil.
  • Coning can occur in horizontal wells near the heel, and in vertical or slightly

  • Prior art ICDs can be of a choke-type, which use chokes, and/or a nozzle, and are based on Bernoulli's principle.
  • conventional choke-type ICDs employ a nozzle to create a drop-in pressure, which can be used to regulate the flow.
  • Other prior art ICD types called tortuous and helical flow path ICDs, employ a flow path formed by constraining walls in which the flow path has numerous corners along the flow axis, which cause numerous directional changes in the fluid passing therethrough, and which can therefore also regulate the flow. Both helical and tortuous flow paths are typically governed by the Darcy-Weisbach equation and can thus be sensitive to changes in fluid viscosity.
  • fluidic or fluid amplification devices are known. These devices typically take one fluid stream and jet it into another, normally at an angle, causing a change in amplification or velocity or even flow direction.

  • fluid such as oil or water act as the conductor, and electromagnetic coils surrounding a flow tube in the magmeter generate the magnetic field.
  • magmeters In principle, a magmeter has two electrodes embedded on opposite sides of the flow tube to sense the signal. The voltage detected at the electrodes is directly proportional to the flow velocity, the intensity of the magnetic field, and the distance between electrodes.
  • a magmeter 100 uses permanent magnets 12' and 12". The fluid flow is shown with the arrow 10, and the electrodes (only one is visible) are denoted by reference numeral 14.

Abstract

L'invention concerne un système de commande d'écoulement d'entrée magnétique (MAG-ICD) pour commander l'écoulement d'entrée de fluide, lequel système est basé sur une variation de conductivité et de la constante diélectrique de fluides en tant qu'indicateur d'une condition de puits. Le MAG-ICD est conçu pour faire varier le débit du fluide s'écoulant dans la colonne de production lorsqu'une percée d'eau est détectée dans le trajet d'écoulement. De cette manière, si le réservoir se rétablit et que le contenu en eau est réduit, le MAG-ICD peut se rétablir et permettre à un écoulement à travers le MAG-ICD d'augmenter. Si la percée d'eau se reproduit, le MAG-ICD répond à nouveau à l'augmentation de la production d'eau et bloque l'écoulement à travers le MAG-ICD. Le MAG-ICD est également conçu pour réduire progressivement l'écoulement dans une zone de production d'un puits lors de la détection d'eau ou de gaz, par opposition au pétrole.
