Abstract

Le procédé de déparaffinage des puits de gaz et de pétrole consiste à mener une opération préparatoire, à introduire dans la zone de formation probable de paraffines un câble de chauffage (5) et à chauffer ce câble en régulant le régime thermique. Au stade préparatoire, on définit la profondeur probable de formation des paraffines, la longueur du câble de chauffage (5) et la puissance de celui-ci en fonction du débit du puits, du point de fusion du matériau d'isolation du câble de chauffage (5) et de la température dans la zone où se trouve l'extrémité de fond du câble de chauffage (5) introduit dans le puits. On régule la consommation du courant utilisé pour chauffer le câble en modifiant le temps de fonctionnement du câble de chauffage (5) et la température dudit câble, qui est régulée et maintenue sur toute la longueur de la partie active de câble de chauffage (5) de manière à dépasser de 5 à 50 °C le point de fusion de la paraffine. On règle la température du flux de produit sortant du puits en fonction de la température ambiante de manière à ce qu'elle soit supérieure d'au moins 5 °C à la température maximale que le produit sortant aurait en absence de câble de chauffage (5). Le câble de chauffage (5) contient au moins deux éléments chauffants (16) isolés l'un de l'autre et disposés dans une enveloppe isolante (17) et connectés par leurs premières extrémités à une source d'alimentation, les autres extrémités desdits éléments chauffants (16) étant reliées entre elles et isolées. Le rapport des résistances électriques des éléments chauffants (16) est sélectionné dans une plage entre 1,0 et 10,0.
