现阶段我国的一些大型油田已近进入了石油开采的中后期,即逐渐从优质油层转向二、三类低渗透油层的开采,这就使得传统的开采方法等不到有效地应用,在增加开采难度的同时也降低了石油的产量,所以需要采取新的开采技术。因此本文对聚合物单管多层分支分压注入技术在大庆油田中的应用进行研究。 At this stage, some large-scale oilfields in our country have recently entered the middle and late stages of petroleum exploration, that is, they gradually shift from high-quality oil reservoirs to the exploitation of second and third low-permeability reservoirs, which makes the traditional mining methods ineffective, such as increasing production The difficulty also reduces the production of oil, so the need to adopt new mining technology. Therefore, this paper studies the application of polymer single tube multi-layer partial pressure injection technology in Daqing Oilfield.
