关于三次采油的经济效益

从我国国民经济的发展速度来看，在未来一段时间内，原油供应将是制约经济发展的一个重要因素。大庆油田再稳产５０００万吨／年将主要依靠三次采油。三次采油离不开聚合物驱和三元复合驱技术。对某区块三次采油工程经济效益的比较表明：聚合物驱将增加可采储量３０％，三元复合驱可增加可采储量５０％以上，适合三次采油的地区应尽快直接实施三元复合驱，以增加开采储量和提高原油产量，增强油田的综合经济实力。

About the Economy Benefit of Enhanced Oil Recovery

With the view of the national economy development, in the recent future, thd crude oil supply is a key factor to the economy increase. If Daqing oilfield can keep its top production for another ten years,the enhanced oil recovery is a very important factor. That is to say, the polymer flooding technology and the temary recombination flooding technology will play the major role in the oilfield production.The area that is suitable to EOR should be directly subject to the technology of ternary recowhination flooding so that to increase the oil production and enhance the integrated economy strengh of the oilfield.
