The Research Of Applied Technology For Profile Control Before Polymer Flooding

Produce Polymer in Polymer flooding is waste Polymer,and it is difficult to treatment the produced liquid, this has brought great difficulties to the oil field development.It is necessary to study and implementation of effective measures to control water-flooding,Improve the effect of the development of polymer flooding,Improve Recovery.because of the number of layers that Development is small,so Profile Control is Important in polymer flooding profile adjustment.article start from this point, to optimize the profile control technology that in use. The final choice is Precrosslinked swellable particles profile control,that the cost is lower and performance is better. To further enhance the profile control targeted. The timing, dosage, slug, the injection method has been optimized,Experiment is done to the expansion of the particles and the capacity of different liquid.in the choice of profile control Well,innovative the means of dentification big channels.Through the implementation of profile control to the well before polymer flooding, Has achieved good results To achieve the purpose of improve the polymer flooding injection profile, improve polymer utilization, improve the effectiveness of polymer flooding.
