Waterflooding Adjustment Technical Evaluation And Application In Chaoyanggou Oilfield

Chaoyanggou oilfield is a typical low,low permeability oilfield,reservoir seepage resistance,pressure conduction ability is poor,has a certain pressure sensitive features,well after the production decreasing speed,water injection is slow.Oilfield development for more than 20 years,took active water drive development adjustment measures,efforts to improve the level of oil field development.Current field is facing the main problems of water cut increase and production decline,the need for step to improve the effect of water flooding adjustment application,therefore,carried out water flooding adjustment technology evaluation and application of the optimization work,mainly analyzed water flooding adjustment technology application effect and regularity,combining with the current fine geologic research,application of numerical simulation technology,optimization of comprehensive adjustment technology,improve the effect of oilfield development.Through the 55 of typical numerical simulation research,through comprehensive adjustment technology application,can improve the recovery efficiency is about 6%.Adjust the 55 extract method as the instruction,Chaoyang oil field water flooding adjustment achieved obviously improved.The future trend of development of the oil field water flooding adjustment technology application for,injection-production system adjustment will continue to rise,thereby expanding linear water injection wellblock,flat water injection structure adjustment will be gradually narrowed,in oil field water cut rising,cyclic waterflooding scale will continue to expand,the depth profile control technology application scale.In short,oil field water injection adjustment workload and well exploration workload to further expand each year,to meet the needs of oilfield development.
