Evaluation the Effect of Profile Controlling Reagent SCA-II Injection at High Temperature by NMRI in Liaohe Oil Field

This paper present a new method of evaluation the injection of profile controlling reagent by NMRI at 200℃ in Liaohe Oil Filed to elimination stream flow along the high permeability layer. With the modern digital NMR SPECTROSPIN 47/40 made in BRUKE Corporation, the reagent first flow along higher permeability layer in the middle of the sample. Then, following stream flood into lower permeability area to increase oil productivity. The velocity of stream flooding into the sample affected the effect by the injection of SCA-II. The higher of velocity of stream flooding, the lager of the permeability rising by following stream. SCAII reagent can not only reduce the permeability in higher permeable area, but also increase oil productivity from lower permeable area.
