    摘要： Method comprising contacting a hydrocarbon-bearing formation with a composition comprising solvent and a fluoropolyether compound, wherein the fluoropolyether compound comprises at least one first divalent unit represented by formula: Each Rf is independently selected from the group consisting of Rfa—(O)t—CHL′-(CF2)n—; [Rfa—(O)t—C(L)H—CF2)—O]m—W—; Rfb—O—(CF2)p-; F(CkF2k)—(O—CkF2K(p—O—CF2—; and CF3—O—(CF2)3—OCF(CF3)—CF2)z—O-L1-. Treated hydrocarbon-bearing formations are also disclosed.
