Innovation and Practice of Key Technologies for Polymer Flooding in Offshore Oilfield
In response to issues such as significant differences in efficiency among polymer flooding well groups in offshore oilfields,limited processing capacity of produced polymers by offshore platforms,a lack of theoretical basis for adjusting and tapping potential,etc.Three key technologies have been innovatively developed:differential flow control for polymer flooding,reasonable prediction of polymer concentration,and determination of reasonable injec-tion production well spacing for polymer flooding.After applying this key technology to mining practice,it effective-ly improves the utilization rate of polymer reagents and increases oil production,reduces the risk of polymer produc-tion doses exceeding the platform's processing capacity and enhances the adjustment and potential tapping effect of polymer injection areas.
