Patent

CA 2446048

The invention relates to jet device used for extracting oil from wells. The inventive device comprises a packer, a pipe column, a jet pump, a transmitter and a receiver of physical fields. The body of the pump comprises a through stepped channel embodied in a parallel position with respect to the axes of the pipe column and having a seat disposed between steps for arranging a sealing unit, which is provided with an axial channel. Said pump body is also provided with an active nozzle. The axis of the active nozzle is disposed in a parallel position with respect to the axis of the through channel at a distance equal to or higher than 1.1 of the radius thereof. The diameter of the through channel above the seat is 0.5 mm greater than the diameter thereof below said seat. The diameter of the axial channel of the sealing unit is equal to or less than 0.6 of the external diameter thereof. The sealing unit is arranged in such a way that it is movable along a cable above a bit and successfully replaceable by the following functional inserts: a blocking insert, depression insert etc. Said inserts are provided with attachments for transporting them to the pump and extracting therefrom and for arranging instruments and samplers thereon. Said invention makes it possible to optimise the dimensions of the elements of the device and increases the reliability thereof.

L'invention concerne un dispositif à jets destiné à l'extraction du pétrole dans un puits. L'appareil comprend un packer, une colonne de tubes, une pompe à jets, une source de rayonnement et un récepteur-convertisseur de champs physiques. Le corps de la pompe comprend un canal de circulation à pas, parallèle à l'axe de la colonne de tubes, qui comprend un logement entre les pas destiné au montage d'une unité d'étanchéité avec un canal axial ainsi qu'une buse active. L'axe de la buse active est parallèle à l'axe du canal de circulation et éloigné de ce dernier à une distance égale ou supérieure à 1,1 rayon du canal de circulation. Le diamètre du canal de circulation est supérieur au logement d'au moins 0,5 mm et supérieur à son diamètre sous le logement. Le diamètre du canal axial de l'unité d'étanchéité s'élève à 0,6 au maximum de son diamètre extérieur. L'unité d'étanchéité est montée de manière à pouvoir se déplacer le long du câble plus haut que l'embout et à permettre son remplacement consécutif par des inserts fonctionnels: insert de blocage, insert de dépression, etc. Les inserts comprennent des dispositifs destinés à leur acheminement et leur extraction depuis la pompe et le montage d'instruments et de dispositifs de sondage. L'invention permet d'optimiser les dimensions de l'appareil et d'augmenter l'efficacité de fonctionnement de celle-ci.
