摘要
本文通过优选井组,合理地应用氮气泡沫驱技术,获得了良好的增油效果,井组最高日增油11.2吨,含水下降5.4%,平均日增油9吨,含水下降4.5%,阶段增油3000吨。
The output of the oil well is improved by 11.2 tons per day by means of well group optimization and nitrogen and foam flooding,and water content declines by 5.4%,the average daily oil enhancement is 90 tons,and average percent of containing water declines by 4.5%,periodical oil enhancement is three thousand tons.
