摘要: 韦2块平均渗透率为(6.1~13.5)×10-3 μm2,是一个较为整装的低渗—特低渗油藏。开发过程中通过采取合理的开发井网,实施注采同步,不断完善注采井网,以及加强注采调控和储层改造等技术,投入开发后油田保持良好的高产稳产态势,连续5年采油速度稳定在1.9%~2.0%,综合含水控制在18%以内,各项开发指标明显好于开发方案。在此重点介绍了韦2断块保持高速高效开发的作法及效果。

Abstract: The average permeability of block Wei-2 is (6.1~13.5) ×10-3μm2, it is a comparatively integral low and super-low permeability reservoir. In the process of developing block Wei2, we took advantage of various development technologies, including reasonable development well pattern, synchronous water injection and oil production, improving injection-production system continually, intensifying adjustment and control of injection-production and reservoir stimulation. From the beginning of development, the field maintains a very good situation of high and stable productivity. The recovery velocity keeps at 1.9%~2.0% in five years, the comprehensive water cut is well controlled below 18% and all kinds of development indexes are significantly better that what they are in development plan.This paper mainly aims at introducing the measures to attainhigh-velocity and high-efficiency development at block wei-2
and the effect.


Key words: block Wei-2, low permeability, synchronous injection-production, high-velocity and high-efficiency, development technology, effectiveness
