Study Of Remaining Oil Distribution And Development Adjustment On The West Section Of Central Saertu Oil Field

This paper focuses on the west section of central Saertu oil field,the remaining oil distribution,as well as development adjustment plan to carry on the forecast,lay the foundation for oilfield production stable.The project mainly established fine phased geological model,based on the application GPTMap software and study of fine geology in actual in experimental area in Central Saertu Oilfield.Through the arrangement,analysis,according to the development characteristic,we set up two dynamic model,the first to establish the water flooding stage fine dynamic model,fine fitting in the reserves,water cut,accumulative total oil,day oil production,we fit the foundation well nets,a well nets,and different period of production of two three combination well network of water cut,oil production,accumulated oil index,and fitting index meet requirements.Then we establish geological model of polymer flooding and a dynamic model of polymer flooding period based on fine water flooding historical fitting,the dynamic model truly reflect the molecular weight polymer stage,concentration,measures of the dynamic change characteristics,by high quality historical fitting,we complete tracking historical fitting work history in experimental area of polymer flooding,and the fitting indexes finished is very good.Based on the above model,we studies remaining oil distribution of water flooding stage and after the current polymer flooding separately and use condition at different reservoirs,study different reservoirs and different types of the reservoir characteristics of remaining oil distribution in the experimental area.On the basis of the remaining oil distribution,and this project mainly forecast from:adjustment of development plan:(1)water flooding oil recovery of a perforation object of the first phase in the well nets conditions.(2)effect role of tracking adjusment measures of the oil wells to improve development.(3)prediction effect to improve the recovery of object of the first phase after the polymer flooding.(4)the second phase of fill holes timing and the design of optimizing the parameters.(5)encryption effect of the water flooding the well nets evaluation to improve oil recovery.
