我国的经济发展的越来越快,随之带来的就是各行各业对于能源的需求大大增加,目前最为重要的能源就是石油,它是我国目前能源供给的基础,加上我国经济持续增长又将导致对于石油的高度依赖,因此石油的勘探和开发对于我国来说具有重大的影响,但是,我国一方面石油资源短缺,一方面石油采收率不高,开发过程中破坏性开采比较严重。我国陆上油田采用常规的注水方式开发,平均采收率只有33%左右,大约有2/3的储量仍滞留在地下,而对那些低渗透油田、断块油田、稠油油田等来说采收率还要更低些,因而提高原油采收率是一项不容忽视事情。本文分析的就是石油工程开采的几种技术。
With the rapid economic development in our country, along with it, the demand for energy of all trades and industries has greatly increased. At present, the most important energy source is oil, which is the basis of our current energy supply. With the continuous growth of our economy Therefore, the exploration and development of oil have a significant impact on our country. However, on the one hand, our country has a shortage of oil resources. On the one hand, the oil recovery rate is not high, and the destructive exploitation in the development process is more serious. China’s onshore oilfields are developed by conventional waterflooding with an average recovery of only about 33% and about two-thirds of the reserves remain underground, whereas for those with low permeability, fault block, heavy oil fields, etc. Yields are even lower, so increasing oil recovery is a matter that can not be ignored. This article analyzes several techniques for the exploitation of petroleum engineering.
