Definitions

  • a well When prospecting for oil or gas, a well is drilled into a formation containing the hydrocarbons, tubing is installed in the well suspended from a wellhead and a christmas tree is placed on the wellhead for controlling the flow of hydrocarbons from the well.
  • a positive hydrostatic pressure difference (internal minus external) is found to be present then the pump is reversed, lowering the pressure in the tubing (and thereby in the tree). Otherwise the pumping pressure is reduced to provide a zero or preferably a slightly negative pressure difference e.g. of about lOOpsi (0.69MNm " ) across the tree walls.
  • the external tree cap can now be removed and a BOP placed on and locked to the tree. Now any necessary refurbishment, modifications or repairs can be carried out on the well or completion (e.g. a leaking tubing hanger or downhole safety valve can be removed through the BOP and riser while maintaining control of the well). After work is carried out, the BOP is removed. The tree cap is mounted to the tree and production can be resumed.

Abstract

L'invention porte sur une pompe réversible submersible (15) reliée à un tubage de production (16) et pouvant servir à élever le fluide de production d'un puits, ou à pomper du fluide d'injection dans la formation (11) cette pompe permet de réduire ou d'inverser la pression de pompage pour permettre d'accéder au puits sans produire de perte substantielle de fluide de production s'échappant dans l'environnement.
