低渗透油田在我国的总油田储量中占有很大的比例,由于低渗透油田的储层物理性质差、渗透机构方式复杂等原因,造成了油田开发难度大、油田产量低等问题。为了解决这些问题,针对低渗透油田的油量开采技术也在不断发展。文章通过分析了低渗透油田的特点,并对目前低渗透油田开采所利用的物理化学技术进行了简单的论述。
The low permeability oilfield occupies a large proportion of the total oilfield reserves in our country. Due to the poor reservoir physical properties of the low permeability oilfield and the complicated infiltration mechanism, the low permeability oilfields cause the difficulty in oilfield development and the low oilfield output. In order to solve these problems, oil extraction technologies for low permeability oil fields are also evolving. The article analyzes the characteristics of low permeability oilfields and briefly discusses the physical and chemical technologies used in the exploitation of low permeability oilfields.
