子北油田贺家湾地区长6油藏超前注水开发分析

Advanced water flooding development analysis of Chang 6 reservoir in Hejiawa area of Zibei oilfield

  • 摘要: 子北油田主力生产油层是长6油藏,属低孔、低渗、低压油藏,地下油水关系复杂,油井采用压裂投产,地层能量特别低,能量亏空严重,产量递减较快。为解决以上问题,通过对该区的地质认识,分析了注水开发的可行性及补充能量的必要性,探讨了注水时机及注水量的确定,为改善子北油田长6油藏开发效果提供借鉴。

     

    Abstract: Chang 6 reservoir is the main producing oil layers of Zibei oilfield, with the characteristics of low permeability, low porosity, low pressure and complicated oil-water relationship underground. If fracturing technoglogy is applied to oil wells, the producing energy is especially low, the energy deficit becomes serious and the production declines quickly. In order to solve these problems, through geological analysis of this area, the feasibility study of water injection and the necessity of supplemental energy have been analyzed. Besides that, the water flooding timing and injected water volume have been discussed, which provides good guidance for Chang 6 reservoir development effect.
