用聚合物驱油提高稠油砂岩油藏采收率

聚合物驱油是提高原油采收率的重要方法之一。我国具有注聚合物驱油提高原油采收率的有利条件。目前,我国主要油区应用聚合物驱油提高采收率的矿场试验,已经取得了一定成果。但要大规模转入工业性推广应用,还要注意利用和创造有利条件、克服不利因素,特别应注重聚合物货源问题、产出油的处理问题、提高经济效益问题,以及综合经济评价问题等等。

On enhancing recovery of viscous oil sandstone reservoirs through polymer flooding

Inpouring polymer flooding is one important process to enhance oil recovery. Our country has the advantages in inpouring polymer flooding to enhance the crude oil recovery. At present, the oil field experiments that the main oil regions in our country apply polymer flooding to enhance crude oil recovery have obtained some achievements. But to change over to industrial popularization and application on a large-scale, we still need to use and create the advantage,overcome the disadvantage factors, especially pay attention to the questions such as polymer goods source, processing oil produced, enhancing the economic efficiency, as well as compositive economic evaluation, etc.
