METHOD AND DEVICE FOR WAVE TREATMENT OF OIL DEPOSIT Russian patent published in 1999 - IPC

FIELD: oil production industry. SUBSTANCE: method and device can be used in operation of wells of low output capacity with purpose of increasing oil recovery. According to method, productive oil bed is periodically subjected to loads through casing string. Treatment is effected in process of operation of standard sucker rod pump which is installed in pump-compressor pipes. Prior to that, secure pump-compressor pipes to casing string within interval of productive bed or above or below it. Height of anchoring zone along casing string is selected so as to meet certain requirement. Device for realization of method has hoisting mechanism in the form of sucker rod pump, string of rods connected by its one end to sucker rod pump, and which by other end is connected to plunger of pump installed inside pump-compressor pipes, string of casing pipes. Introduced is anchor for transmitting treatment to deposit. Anchor is installed between pump-compressor pipes and casing string and is secured to walls of pump-compressor pipes and casing string. Application of aforesaid invention allows for increasing oil recovery without removing wells from operation for period of wave treatment. EFFECT: higher efficiency. 6 cl, 2 dwg
