To take common heavy oil reservoir of typical small fault block--Bi-124 fault lower series of Gucheng oil field as an example, this paper studied on the reservoir widely polymer flooding tracking numerical simulation and than optimized the polymer flooding tracking adjustment guiding by the sensitive parameters related to injection/recovery. The study took suitable pattern spac-ing, optimizing profile modification opportunity and timely effective anti-channeling measures and adjusted the consistency of the polymer and the high efficiency tracking adjustment technique such as tubing-casing zonal injection to get Ideal stimulation effect in this block. In response fastigium, daily oil production went up to 80 t/d from 47.5 t/d, composite water cut fell down to 68.0%from 83.6%, sectional polymer-oil displacement rate reached 47.7 t/t and the recovery increased by 5.7%. It had obtained great development effect.
