| Abstract: | Based on the exploitable condition of unit 9-10 in second zone of Shengtou Oilfield,the oil reservoir production feature is analyzed. Aimming at plane and interlayer anisotropism of the unit,and combining with the principle of hydrodynamics,the effect of water displacing oil has been improved by periodic and supercharge water injection.During 5 years operation,the dynamic production condition is getting better in this unit.Daily crude output is higher than past.The recovery efficiency in this unit has improved by 9.62%.The exploitable reserve has increased 341,500 tons.For the same type of anisotropism oil reservoir,this method is valuable for improving the effect of water displacing oil and enhancing the final oil recovery efficiency. |
