METHOD FOR DEVELOPMENT OF OIL DEPOSIT Russian patent published in 1999 - IPC

FIELD: oil production industry. SUBSTANCE: method can be used for development of oil deposit with high flooding of recovered product. According to method, working agent is injected through injection wells and oil is recovered through producing wells. Injection wells are operated in cyclic mode that is "injection-stopping". In one of half-cycle "stopping", seismo-acoustic emitter is installed in injection well in upper part of productive interval. Seismo-acoustic treatment is carried out during 20-40 min. Seismo-acoustic emitter is displaced along productive interval with stoppages after every 250-500 m for period of 20-40 min for performing seismo-acoustic treatment. Operations are repeated after 6-50 months. Application of aforesaid method ensures reduction of flooding of recovered product together with increasing oil recovery from deposit. EFFECT: higher efficiency.
