METHOD OF CONTACTING HYDROCARBON-BEARING FORMATIONS WITH FLUORINATED IONIC POLYMERS |
摘要 |
A method is disclosed that includes contacting a hydrocarbon-bearing formation with a treatment composition comprising solvent and a fluorinated polymer. The fluorinated polymer includes: a first divalent unit represented by formula (I): wherein Rf represents a fluoroalkyl group having from 1 to 8 carbon atoms; each R1 is independently hydrogen or methyl; Q is a bond or —SO2—N(R)—, wherein R is alkyl having from 1 to 4 carbon atoms; and m is an integer from 1 to 11, a second divalent unit comprising a poly(alkyleneoxy) group; and a third divalent unit comprising a pendant ionic group. The solvent includes not more than ten percent by weight methanol and not more than 25 percent by weight water, based on the total weight of the solvent, and/or the solvent solubilizes or displaces brine in the hydrocarbon-bearing formation. Treated hydrocarbon-bearing formations are also disclosed. |
