Research On Water Injection Countermeasures In ShuangHe Olifield XiQu No.8 Station

Based on the analysis of all kinds of information, the study area after the implementation of water injection, the formation pressure gradually increased, the reservoir decline significantly reduced, water injection improved the oilfield situation, but the oillayer energy shortage, the vertical water absorption, high water cut and other issues still exist.For further tapping the potential of reservoir, to ensure that future oil production continued to increase stability, realize the yield and production target.Through the use of the study area of well logging data, drilling data andcore analysis data, made fine division and correlation of the small layer on the Chang6, sedimentary facies and distribution of sand body,reservoir characteristics research, and combined with the reservoir characteristics and laws of, comprehensive evaluation of the effect of water flooding reservoir and analysis influence factors currently oil production, puts forward the yield and production countermeasures, for improving the effect of oilfield development.
