Title
(EN) METHOD FOR FORMATION TREATMENT OF WELL BOTTOM ZONE
(FR) PROCEDE DE TRAITEMENT DE FORMATION D'UNE ZONE DE FOND D'UN PUITS
Abstract
(EN)
The method relates to the obtention of oil and provides for feeding a bactericidal agent into a well bottom zone of a developed formation. Gamma radiation is used as the agent, the dose of its radioactivity is not less than 150 krad, whilst the pressure in the well bottom zone is maintained during the radiation thereof in the range from 2 to 50 MPa.
(FR)
Le procédé concerne l'obtention de pétrole et assure l'alimentation en agent anti-bactérien dans une zone de fond d'un puits d'une formation développée. On utilise comme agent une radiation gamma, dont la dose de radioactivité n'est pas inférieure à 150 krad, tandis que la pression dans la zone de fond du puits est maintenue pendant son irradiation dans la plage de 2 à 50 MPa.
