低渗透油田的油藏特点主要表现为孔喉半径小、渗透率低、渗流阻力大等特点,随着油田开发主体技术的推进发展,开采进程早的老油田得以持续有效深化开发,原来认为难以开采的低渗-特低渗油藏得到有效开发动用,使得资源的利用率和石油的保障供给能力得到大幅度提高.%The characteristics of reservoirs in low-permeability oilfields are characterized by small pore throat radius, low permeability and large seepage resistance. With the development of oilfield development main technology, the old oilfields with early mining process can continue to effectively deepen and develop. The low-permeability-extra-low-permeability reservoirs, which are considered to be difficult to mine, have been effectively exploited, resulting in a significant increase in resource utilization and oil supply.
