- 摘要:
- 为了解决HZ油田特低渗油藏在开发过程中存在的自然产能低、产量递减快、常规开采方式无法实现经济有效开发的问题，以数值模拟为手段结合现场开发试验,主要从合理注水时机、周期注水、注气开发等方面开展综合研究,确定合理注水时机为超前6个月注水,合理周期注水方式为短注长停不对称型周期注水,注水效果差的油藏有效开发方式为注气开发。从现场实践来看,已经取得一定的效果,为该地区同类型特低渗油藏的经济有效开发提供了技术支撑。
To solve the issues such as lower natural productivity, faster production decline, failure to achieve economical-effective development via conventional production methods represented by the development of extra-low permeability reservoirs in HZ oil field, field development test, combining with numerical simulation, is carried out to for comprehensive study from proper timing of water injection, cyclic water flooding, gas injection etc. It is confirmed that the proper timing for water injection is 6 months in advance and the method for cyclic water flooding is asymmetric types featured by short injection and long suspension. The method for effective development of reservoir with poor water injection performance shall be gas injection. Achievements have been made from field practice, which provides technical guidance for the economical-effective development of extra-low permeability reservoir in this area.
