作为一种非再生的化石能源,石油采收率不仅是石油工业界,而且是整个工业界普遍关心的问题。由于石油是一种流体矿藏而带来的独特的开采方式,所以在各种矿物中石油的采收率是比较低的。在世界范围内,石油的采收率平均约在30～90％之间。在目前条件下,当一个油藏停止开采时,油藏中仍然残留着大量石油,而采出油量仅占其中较少的一部分。如何把遗留在油藏中的石油经济有效地开采出来,是石油工作者多年来一直在不断探索的一个问题。本文仅就三次采油技术作一些探讨。
As a non-renewable fossil energy source, oil recovery is not only the oil industry, but also the general concern of the whole industry. Because petroleum is a unique mining method that results from fluid deposits, the recovery of petroleum from various minerals is relatively low. In the world, the oil recovery rate on average about 30 to 90%. Under the current conditions, when a reservoir ceased mining, there was still a large amount of oil remaining in the reservoir, while only a small part of it was produced. How to mine the oil left in the reservoir economically and efficiently is one of the problems that oil workers have been constantly exploring for years. This article only on the tertiary oil production technology for some discussion.
