Then, a ball with a diameter of 19 mm is lowered into the pipe cavity, which, passing through the HKT suspension, the shear circulation valve 6 and the hollow rod filter 10, is lowered into the seat 13 of the rod filter 10 and overlaps the central channel 14 of the pusher 11, after which HKT creates working pressure.

  • the technical and economic advantages of the proposed perforator are as follows. 1. Due to the implementation of the cutting unit, consisting of two cutting discs and two monitor nozzles, the formation of two diametrically located slots in the production casing is ensured simultaneously. 2. Due to the creation of efforts in the formation of two opposite slots, the device is not pressed against the production casing, which eliminates the loss of effort to overcome the friction forces when moving the device up and down. There is no wear of the device case, the production casing does not bend if there is no cement stone behind it.
  • the piston-pusher with a wedge support-fork performs the function of both a piston and a pusher, in addition, it provides the supply of working fluid during direct flushing of the device and the flow of fluid to two monitor nozzles.

Abstract

La présente invention relève du domaine du forage et de l'exploitation de puits, et concerne précisément un dispositif destiné à former des fentes de perforation dans une colonne de tubage, un ciment durci ou une roche. Le perforateur selon l'invention comprend un corps, un outil de coupe télescopique se présentant sous forme de deux disques de coupe placés sur des axes, un piston-poussoir possédant un canal hydraulique central et deux canaux hydrauliques latéraux, lesquels sont dotés de deux buses à jet. Lesdits disques assurent la formation de deux fentes disposées diamétralement dans la colonne. Un bras oscillant se présentant sous la forme de deux plaques profilées dotées d'ouvertures est monté sur l'axe central, lesdites ouvertures contenant les axes des disques. Un mécanisme d'extension des disques de coupe permet d'éviter tout contact entre le corps du perforateur et la colonne. La rotation du bras oscillant avec les disques est assurée par son interaction avec une fourche en V placée sur la partie inférieure du piston-poussoir.
