CA 2641601

A method and apparatus for inserting a small diameter continuous hydraulic conduit or capillary tube down a well bore is presented. The methods and apparatus allow either the injection of chemicals to enhance production of oil and gas, or to provide a conduit for production up through the small diameter tubing in marginal wells, into a hanger below a well valve to permit its removal from below the valve if the valve should be required to be closed and its reinsertion without pulling the tubing from the well bore.

Il s'agit d'un procédé et d'un appareil pour insérer un tube capillaire ou un conduit hydraulique continu de petit diamètre dans un trou de forage. Les procédés et appareils permettent d'injecter des substances chimiques destinées à améliorer la production de pétrole et de gaz ou de disposer un conduit d'extraction à travers le tubage de petit diamètre dans des puits marginaux, dans un dispositif de suspension sous une vanne de puits de façon à permettre son retrait du dessous de la vanne si cette dernière doit être fermée et sa réinsertion sans qu'il soit nécessaire de sortir le tubage du trou de forage.
