METHOD FOR PERFORATION OF WELLBORE Russian patent published in 1994 - IPC

Abstract RU 2017944 C1

FIELD: well operation. SUBSTANCE: used as active body for charging the device is liquid fuel mixture consisting of reflux titrated fuel and oxidizer. Used as fuel is, e.g., aromatic and fat amines with addition of nitrobenzene. Used as oxidizer is, e.g., composition based on nitric acid or nitrogen tetroxide. Perforation device is finally charged after its lowering into the well by supplying components of active body to high-pressure chamber in portions and separately. After each perforation effect, the depth of device is changed. EFFECT: higher efficiency due to reduced time for perforation within preset interval and reduced dynamic loads on wellbore. 2 cl, 1 dwg
