低渗透油田提高采收率技术研究及应用

Low permeability reservoir and application of enhanced oil recovery

水驱油藏提高采收率的方法主要为化学法,化学法包括化学调剖和化学调驱,主要对化学调剖中的注水井深部化学调剖和注水井暂堵酸化以及化学调驱中的表面活性剂驱和空气泡沫驱进行了研究及评价。

Water drive reservoirs to enhance oil recovery methods are mainly chemical method, including chemical profile and chemical profile control, this paper on the chemical profile of the water injection well depth profile and the department of chemistry, injection well plugging acidification, and chemical control and flooding in surfactant flooding, and air bubbles were driven research and evaluation.
