Secondary completion technology with 60, 73 mm diameter tubing run perforator geophysically linked to cross-section allows forming large-length longitudinal split with roll-on disk (all-point loading metal plastic deformation principle) in the required casing interval, and washing a cavity with fluid jetting in the cement ring and rock.

• higher hydrodynamic quality of formation exposing due to exposing with a slot of all fluid-conducting channels;
• specific exposure area is for 80-90% higher than at jet perforating with maintained casing strength;
• penetration radius is 2 times higher compared to jet perforating;
• no impacting casing during perforation;
• no impacting cement stone outside casing upper and lower perforating interval;
• allows for selective exposing of only producing interlayers without breaking barriers between them;
• allows exposing formation with oil or any other working fluid;
• allows for reperforation with simultaneous treatment of transition zone;
• the operation can be performed at any time of day and does not require turning-off electric energy supply;
• if necessary, a well can be produced through perforator till the next workover;
• costs is not higher than for jet perforation method;
• allows effectively removing outside-casing cross-flows;
• increases well intake capacity before emergency cementing/fracturing.

Perforator designed is protected by RF patent.
