Abstract: front page image
(EN)Running an isolation device into the well and using the isolation device to form a seal to create a first region of the well isolating the surface of the well from a second higher pressure region of the well, further including running an assembly into the first region and engaging the isolation device with the assembly to remove the seal. After removal of the seal, the isolation device and assembly are run together further into the well. With this technique longer assemblies can be inserted into the well than is possible with possible with the use of a conventional lubricator.
(FR)L'invention concerne une technique utilisable avec un puits, consistant à faire passer un dispositif d'isolation dans le puits et à utiliser ce dispositif pour former une isolation qui permet de créer une première zone de puits isolant la surface du puits par rapport à une seconde zone de pression supérieure dans le puits. On fait passer un ensemble dans la première zone et on enclenche le dispositif avec cet ensemble pour éliminer l'isolation. Une fois l'isolation éliminée, on fait avancer ensemble le dispositif d'isolation et l'ensemble plus loin dans le puits.
