Research On The Plan To Optimize The Relationship Between Injection And Production Of Gaotaizi Reservoir

The long term production of oil field brings rigorous test on the future development of reservoir.Faced with the problems that replaced reserve volume lack,quantity of remaining recoverable oil can't be produced easily,the production of major reservoir decrease sharply,stable yields of oil can't be kept,interlayer interference between thin and poor layers,and so on,water flooding is still the most important way to keep consist stable yields of reservoir.When come into double-high production period,the potential of water flooding to infill well pattern has decreased,so keeping current well pattern disposition,exploring the optimize between injection and production and improving the produce degree of reservoir will be a main direction to adjust production plan after the high water cut stage.This paper aiming at the deposition characteristics of Gaotaizi reservoir,carry out the fine dissection,then ensure the style and distribution regularity of remaining oil.It also estimate the well pattern adaptability of Gaotaizi reservoir in east of South II field,therefore carry out the study on how to optimize the relationship between injection and production of Gaotaizi reservoir.According to the current well pattern distribution,and based on numerical simulation,we study and optimize the adjustment model of different fields' relationship between injection and production through building geologic model.At the same time,we coordinate injection flow rate with relationship between injection and production of new wells and old wells,make up a way to optimize the injection and production relationship in Gaotaizi reservoir,which has a guidance meaning to improve the water flooding effect in high water cut rate.
