Improvement of devices of abrasive jet perforation in oil wells

UDK: 622.245.142.4
Key words: enhanced oil recovery (EOR) methods, bottomhole formation zone, abrasive jet perforation, oil production problems
Authors: N.I. Krysin, E.P. Riabokon, M.S. Turbakov, S.E. Chernyshov, A.A. Shcherbakov (Perm National Research Polytechnic University, RF, Perm)

Well stimulation and provision a future sustainable hydrodynamic connection in the ‘well – reservoir’ system is performed using perforating devices by creating channels in casing and cement annulus. Oil well completion technologies does not always lead to project oil flow rates as a result of the negative impact on the bottomhole formation zone of drilling and cement slurries, perforation and well killing fluids, resulting in deterioration of reservoir properties of productive layers.

The article describes an abrasive jet perforation, as the most effective, with which an initial permeability of the rock is preserved, an effective radius of the well and a filtration area are increased. The authors have developed a device for the abrasive jet perforation in oil wells, which differs from the previously developed by setting bushings fixed using a clip into the holes of a movable cup; location of jet nozzles along the body in a spiral; presence of a groove in the movable bushing, in which a plug end is pushed (the plug is mounted into the hole in the body of the perforator); separating a spring of the movable cup from a movable rod by tubular elements, which allows to start removing mechanical particles from the well after perforation without switching to backwash and stopping circulation. The device provides a quality perforation of productive oil layers, increases the durability and reliability of operation, allows to create a hydrodynamic connection in the ‘well – reservoir’ system without deterioration in the initial reservoir properties of productive formation. Conducting the abrasive jet perforation using the developed device allows to prepare the well for a directed hydraulic fracturing.
