西峰油田白马南井区由于储层物性差、渗流阻力大等原因,导致油藏开发难度大,严重影响油田稳定生产。通过对井网形式、注水方案等研究,提出采用菱形井网、超前注水等措施进行开发,从而提高油田开发效率,有效控制油田递减率,使采收率基本保持在20%,接近标准采收率,实现特低渗油田的稳定生产。
Due to the poor reservoir physical properties and large seepage resistance, the south bank area of Baima in Xifeng Oil Field has caused the difficulty of reservoir development and seriously affected the stable production of oilfields. Through the research on well patterns and water injection schemes, it is proposed to use rhombus well pattern and advanced water injection to develop the oilfield so as to improve the oilfield development efficiency and effectively control the decline rate of the oilfield so that the oil recovery rate will remain at 20%, which is close to the standard recovery Rate, to achieve stable production of ultra-low permeability oilfield.
