POLYMER-THERMAL
TREATMENT TECHNOLOGY
Combined Treatment
Technology combines thermal
formation treatment with polymer flooding.
The technology is carried out in
three stages:
:
creation of polymer solution border;
The second stage :
creation of heat carrier fringe;
The third stage :
pushing through of heat carrier fringe with cold water.
The Technology allows to increase
a layered-nonhomogeneous reservoir treatment coverage by leveling-off filter
resistance of various permeability laminas due to residual resistance factor.
It allows to ultimate oil
recovery increase for 5 - 6% with heat carrier economy of 8 -10%.
The Technology is designed for
application at high-viscosity oil deposits in terrigenous non-homogeneous
reservoirs.
It increases duration of
water-free oil production stage and decreases well production water-cutting rate.
The Technology is protected by
certificate of authorsip № 1156424.
The Technology was tested and
implemented at Karazhanbas oilfield (See Fig.).
