| 摘要 |
The invention provides a method of treating a subterranean hydrocarbon-bearing formation comprising unconsolidated or poorly consolidated particulates, the method comprising contacting the formation with a solution or a dispersion of an organosilane, characterised in that the organosilane is a silylated polymer of formula (I)wherein each R is independently a substituted or unsubstituted alkyl having from 1 to 6 carbon atoms or a -C(O)R group where R is as hereinbefore defined; n is 0, 1 or 2; each A is an alkoxy linking group; and B is a polyoxyalkylene linking group, a polyurethane linking group, or a poly(meth)acrylate linking group wherein the polyoxyalkylene linking group or the polyurethane linking group has a number average molar mass in the range of 600 to 20,000 g×moland the poly(meth)acrylate linking group has a number average molar mass in the range of 600 to 40,000 g×mol. |
