The Scheme Optimization Of Surfactant/polymer Flooding In Jin 16 Block

Jin 16 piece of Liaohe oilfield after decades of waterflood development,at present there is an difference of oil Wells well conditions,imperfect injection-production well pattern,the reservoir water level is extremely high,need to adopt a new oil displacement method for mining.Jin 16 piece of the early stage of the water flooding development effect reflects the block water drive recovery factor,the utilization rate of water flooding,injected water ripple degree is higher,the well fluid producing ability,basic ? type of reservoir development.In this paper,through the jin 16 piece of reservoir numerical simulation,fitting of the reserves and the status of the historical development,provide the basis for subsequent development plan optimization.Summary of reservoir remaining oil distribution and the distribution characteristics,combined with the indoor experiment,think jin 16 piece of reservoir has the necessity and feasibility of chemical flooding development.Through to the dual test scheme is optimized,finally determined the jin 16 piece of open using binary flooding well pattern and well spacing and other mining scheme;To predict the development indexes of binary flooding,for jin 16 piece of dual drive efficient development provides the technical guidance.
