随着经济的发展,石油资源成为社会正常运转中一种不可或缺的能源,对于交通、冶金、航空航天等多个领域产生着巨大的影响,社会对于石油的需求与日俱增。我国石油储量并不占优势,且在待开采油田中,低渗透油层占据着较大的比例。如何提高低渗透油田的开采效率,提高资源的利用率,减少不必要的资源浪费,是石油企业必须重点关注的问题。本文结合低渗透油层的特性,对其物理化学采油技术进行了分析和研究。
With economic development, petroleum resources have become an indispensable energy source in the normal operation of society and have a huge impact on many fields such as transportation, metallurgy and aerospace. The demand for petroleum from the society is increasing day by day. China’s oil reserves are not dominant, and in the field to be exploited, low permeability reservoirs occupy a large proportion. How to improve the exploitation efficiency of low permeability oilfields, improve the utilization rate of resources and reduce the unnecessary waste of resources are the problems that petroleum enterprises must focus on. Combined with the characteristics of low permeability oil reservoir, this paper analyzes and studies its physical and chemical oil recovery technologies.
