METHOD FOR PHASE-EXPLOSION EFFECT IN WELL Russian patent published in 2005 - IPC

Abstract RU 2250366 C2

FIELD: oil industry.

SUBSTANCE: method includes lower heat energy source and implosion chamber into well. Heat effect is applied and phase-explosive process is launched by opening implosion chamber. Implosion chamber is opened after reaching maximal temperature of well liquid at the very beginning of its decrease. Then phase-explosive process launch temperature is decreased. At second object method includes lower heat energy source and air implosion chamber into well. Heat effect is applied and phase-explosive process is launched by opening air implosion chamber. Air implosion chamber is positioned at distance from heat energy source, where well liquid temperature provides for launch of phase-explosive process, or air implosion chamber is opened with a delay. By these, excessive energetic potential of phase-explosive process is prevented with destruction of casing column and cement stone. Power of phase-explosive process is limited by use of air chamber under pressure.

EFFECT: higher efficiency.
