摘要：

This paper describes efforts in an experimental search for polymers that are sufficiently soluble in dense CO//2 that they could serve as mobility control agents. The operation of the apparatus designed and built for the measurement of solubility in condensed gases is described. A modified version of this apparatus has been used to measure viscosity by timing the fall of a cylinder in a tube. Also discussed are considerations involved in the application of direct thickeners in the mobility control of CO//2 floods and the advantages in the use of such CO//2-soluble polymers in place of methods that involve the injection of water.
