非混相泡沫段塞细分层注水关键技术
Key technology for immiscible foam slug fine separate-layer water injection
摘要
Abstract
According to chemicals in the reservoir after absorption of effectiveness, and foam fine separate-layer water injection long slug continuous injection way is easy to cause the steam breakthrough and absorb fluid profile reverse against the whole measure effect, using target reservoir oil sands to fill the model, investigating regeneration of agents after dynamic absorption and foam comprehensive property, contrasting foam small slug interval injection and long slug continuous injection effect of increase shunt. The results indicate that the different agents after absorption in porous media, regeneration and foam comprehensive performance decreased, but effective gradually increases as for flooding volume increasing; Foam small slug interval injection is better than long slug continuous injection way. Field application feedback that foam small slug interval injection can increase 23 cubic meter, water cut increasing by 2. 6%, in all increased oil improve 17200 cubic meter, improving the validity of 7 months above than long continuous injection way, further verify the foam small slug interval injection technology is superiority.关键词
