METHOD OF WELL PRODUCTIVITY INCREASING Russian patent published in 2002 - IPC

Abstract RU 2191259 C2

FIELD: methods of oil recovery intensification. SUBSTANCE: method includes location of fluid with propping agent in interval of producing formation; lowering of powder pressure generator into well; hydraulic fracturing of formation by pressure of powder gases. Preliminarily installed in well above producing formation is fluid packer in the form of column of plastic, or pseudoplastic, or viscoplastic fluid. Powder pressure generator is installed in interval between producing formation and fluid packer. EFFECT: higher efficiency.
