Definitions

  • the elevation system proposed here is intended for wells with very low static pressure (close to the head pressure) that operate with intermittent pneumatic elevation.
  • the pneumatic intermittent wells are traditionally equipped with obturator (packer), foot valve (standing-valve) and gas-lift valve that is positioned above the obturator.
  • This type of installation provides a relatively low flow pressure, but it can reduce or even prevent the production of wells with very low static pressure.
  • the use of an insertable chamber is an alternative to overcome this problem, but it had the inconvenience of not allowing the replacement of the gas-lift valve with a wire unit (without probe intervention).
  • the document GB2257449A discloses a production system for a subsea well that includes a concentric gas-lift line and a production column, both located within a production riser.
  • a gas lift chuck, and associated apparatus, are provided on the pipe hanger to allow gas to be selectively directed downward to a lower gas-lift valve located deeper within the well.
  • the document US5785124A discloses a method to increase the production of an oil well.
  • the method comprises the steps of installing a venturi device inside the well, where the venturi can be associated with a gas-lift chuck located in the well.
  • Document W01996007813A1 discloses a gas flow control device for injecting gas into a production column to recover pressure and reduce friction losses so that critical flow can be achieved at low pressures and at production pressures higher.
  • a Venturi is used on the side pocket chuck so that the Venturi flow path is coaxially aligned with the nozzle flow path to provide a continuous flow path.
  • the invention presents a concentric mandrel and hanger, which uses the same gas-lift valve used in side bag mandrel.
  • the application of the invention is proposed for wells with very low static pressure that operate with intermittent pneumatic elevation, enabling production in these wells.
  • the development of the concentric mandrel and the respective macarroni hanger (1) allows the use of an insertable accumulation chamber, and at the same time allows the replacement of the gas-lift valve to be carried out with a wire unit, thus avoiding probe interventions, which are more costly and time-consuming.
  • FIG. 1 illustrates the concentric chuck with pneumatic lift valve installed.
  • FIG. 2 illustrates a well equipped with an insertable chamber with a concentric mandrel.
  • FIG. 3 illustrates the suspender nipple of the macarroni tube
  • FIG. 4 illustrates a sectional view of the concentric mandrel.
  • the hanger (3) is lowered together with the macarroni tubes (1) during the probe intervention, being installed in the recess of the tube sleeve (2) with NU or EU thread.
  • the concentric mandrel (8) is coupled just above the hanger (3) and snaps into it during the threading of the connection.
  • the bottom assembly has the following elements: Concentric Nipple (8) for 1.1/2 in. gas-lift valve (5) and Suspender Nipple (3) for 1,315 in. NU pipe column ( 12);
  • FIG. 1 illustrates the concentric chuck (8) with gas-lift valve (5) installed.
  • the inlet of the gas from the ring (13) occurs through the side (6) and the outlet from below.
  • Figure 2 illustrates a well equipped with insertable chamber (14) with concentric chuck (8).
  • the gas flow passing through the pneumatic lifting valve (20) pushes the liquid that initially passes through the concentric mandrel (8) and (22) itself and then rises to the surface;
  • FIG. 3 illustrates the suspender nipple (3) of the macarroni tube (1) that is installed below the concentric mandrel (8).
  • this hanger (3) has an upper seal that attaches to the mandrel and has side holes (21) to allow the passage of liquid and gas during the lifting phase;
  • Figure 4 illustrates a sectional view of the concentric chuck.
  • the gas-lift valve (5) and peripheral annular space (21) the passage of liquid and gas during the ascent occurs;

Abstract

L'invention concerne un mandrin concentrique et un suspenseur, utilisant la même vanne de gaz-lift que celle utilisée dans un mandrin à poche latérale. L'invention trouve une application dans des puits à très faible pression statique qui fonctionnent avec une élévation au gaz intermittente, permettant la production dans ces puits. La mise au point d'un mandrin concentrique et du suspenseur respectif de tube macaroni permet l'utilisation d'une chambre d'accumulation apte à l'insertion, et permet dans le même temps d'effectuer le remplacement de la valve de gaz-lift avec une unité à fil, évitant ainsi les interventions par sonde, qui sont plus onéreuses et plus longues.
