Method and apparatus for melting a material and squeezing the melted material through casing perforations into a fault within the cement or formation of an oil or gas well. A heating tool carries solid material which is melted at depth within the well and adjacent to the casing perforations. The liquefied material is forced through the perforations and into the formation or the well cement. When the material cools and solidifies, the faults become sealed.
L'invention concerne un procédé et un dispositif permettant de faire fondre un matériau et d'injecter le matériau fondu à travers des perforations du tubage, dans un défaut du ciment ou de la formation dans un puits de pétrole ou de gaz. Un outil chauffant transporte le matériau solide qui est fondu en profondeur à l'intérieur du puits, à proximité immédiate des perforations du tubage. La matériau liquéfié est injecté sous pression dans la formation ou dans le ciment du puits à travers les perforations. En se refroidissant et en durcissant, le matériau scelle les défauts.
