红浅1井区齐古组油藏加密区生产效果评价

针对红浅1井区齐古组油藏采出程度低、井网井距大、剩余油饱和度高的实际情况，对齐古组油藏进行了加密开发。对2009年到2010年部署的加密井生产效果进行跟踪评价分析，通过动静态结合的方法，对加密区的新老井的生产特征进行了总结分析，总结了影响加密区新井生产效果的因素，论证了齐古组加密开发的可行性和风险性，为今后齐古组加密开发和生产管理提供参考和依据。

Evaluation of the production performance of oil reservoir of Qiguzu in Well Block Hongqian-1 infilling area

Oil reservoir of Qiguzu in Well Block Hongqian-1 was developed beginning in 1991.Up to now,it has been produced for 20 years,which is going into the late stage of development,and relying on the current mining methods can not improve development effectiveness and increase ultimate oil recovery.So,from 2009,for the actual situation of low recovery percent of reservoir,long well spacing of well pattern and high residual oil saturation,oil reservoir of Qiguzu in this block was developed by infilling.On the basis of geological characteristics of the oil reservoir of Jurassic Qiguzu in this block,for 2009 to 2010 infilling well on the deployment of tracking the effect of infilling production evaluation and analysis,by the method of combining static and dynamic,the old and new wells in infilling area’s production characteristics were analyzed,and the impact of the new wells in infilling area’s effect of the factors of production wells were summed up.At last,Qiguzu infilling development feasibility and risk were demonstrated which provided the reference and basis for future Qiguzu infilling development and production management.
