Abstract

Abstract:

In the light of the practical conditions of the two wells, an injection profile medifier bas been developed, which has the properties of in situ gelation and adjustable gelation time. A system evaluation has been given to its properties in laboratory through core flooding experiment, and the measurement of gelation time in porous media has been proposed. A good result has been achieved in the in situ modification operation. Thus the oil production increased and the injectivity profiles of the injection wells greatly improved after the modification.

Key words: Water injection well, Injectivity profile, Injectivity index, Permeability, Profile control, Polymer
