摘要： The present invention relates to improved viscosification agents for a variety of aqueous solutions which comprise a family of intramolecular polymeric complexes (i.e., polyampholytes) which are copolymers of metal styrene sulfonate/methacrylamidoproplytrimethylammonium chloride (MAPTAC). The metal styrene sulfonate is an anionic monomer, while MAPTAC is cationically charged. These polyampholytes have approximately 1 to about 99 mole % of the anionic monomer and approximately 1 to about 99 mole % of the cationic moiety present within the macromolecular structure. These groups are not necessarily present in an equimolar charge ratio. The excess undissociated charge allows for facile dispensability or solubility of the polyampholytes into low ionic strength aqueous solutions.

摘要： The present invention relates to a process for the plugging of a porous formation which may be encountered during the drilling of a well. The process entails plugging of the porous formation by means of a polymeric solution containing pseudo-emulsion spheres. These particles penetrate the pore structure within a formation. Eventually, sufficient numbers of the spheres will accumulate within the pores, blocking further flow through the formation by both the pseudo-emulsion particles and any aqueous solutions. The pseudo-emulsion system is formed by a process which includes the steps of forming a solvent system of an organic liquid or oil and a polar cosolvent, the polar cosolvent being less than about 15 weight percent of the solvent system being less than about 100 cps; dissolving a neutralized sulfonated polymer in the solvent system to form a solution, a concentration of the neutralized sulfonated polymer in the solution being about 0.01 to about 0.5 weight percent, a viscosity of the solution being less than about 200 cps; and admixing or contacting said solution with about 5 to about 500 volume percent water, the water being immiscible with the organic liquid and the polar cosolvent and neutralized sulfonated polymer transferring from the organic liquid to the water phase, thereby causing the water phase to gel (i.e., thicken).

摘要： The present invention relates to a process for the viscosification of an organic liquid which comprises the steps of forming a first solution of an anionic polymer dissolved in the organic liquid; forming a second solution of a cationic polymer dissolved in the organic liquid; and mixing the first and the second solutions together to form an interpolymer complex of the anionic and cationic polymer in the organic liquid, wherein the organic liquid containing the interpolymer complex has improved viscosification properties. This solution possesses higher viscosity than the mean of the separate viscosities of the starting solutions at relatively low solids content. Moreover, these interpolymer complexes, in hydrocarbon solutions, can be formulated to exhibit shear thickening at increased shear rates. This property is useful in such technological applications as antimisting of the solvent.
