摘要： A method of stabilising fines such as within a permeable subterranean formation comprises contacting said fines with an effective amount of a polymer having repeating monomer units of the general formula:
wherein
R, is an alkyl group having from about 2 to about 5 carbon atoms, and preferably propyl; R 2 is an unsubstituted alkyl group having from about 2 to about 6 carbon atoms or a substituted alkyl group having from about 2 to about 6 carbon atoms and containing a hydroxy group or from about 1 to about 3 ether groups, and preferably 2-hydroxypropyl; X is an anion selected from the group consisting of chlorine, bromine, iodine, sulfate, hydroxyl, methyl sulfate and mixtures thereof; m is an integer equal to the number of anions required to maintain electronic neutrality; and, y is an integer equal to the number of monomer units in said polymer required to increase the viscosity of deionized water to from about 250 centripoises to about 1,000 centipoises as measured by adding 40 grams of the polymerto 60 grams of deionized water to form a solution and measuring said viscosity of said solution on a Brookfield Model LVT viscometer, No. 3 spindle, 6 r.p.m. at about 76°F (24.4°C).

摘要： A method of preventing or reducing the migration of fines in a permeable structure such as an earthen formation, comprising contacting said fines with an effective amount of organic copolymer having a molecular weight of from about 1,000 to about 3,000,000 and having recurring structural monomer units formed in a random fashion of the formula:
wherein

R 1 and R 2 are independently methyl, ethyl, hydroxyethyl or hydroxymethyl;
R 3 is an unsubstituted alkylene group having from about 2 to about 4 carbon atoms or a sustituted alkylene group having from about 2 to about 4 carbon atoms and containing a hydroxy group;
R 4 is methyl or ethyl;
R 5 is hydrogen or methyl;
M is hydrogen or an alkali metal; and,

monomer unit I is present in the range of from about 5 to about 30 weight percent of the copolymer and monomer unit II is present in the range of from about 70 to about 95 percent by weight of the copolymer.

摘要： A method of preventing or reducing the migration of fines and/or the swelling of clays in a permeable subterranean formation, comprising: contacting said fines or clays with an effective amount of an organic polycationic polymer having a molecular weight in the range of from about 50,000 to about 300,000 and having monomer units of the formula:

wherein R and R 3 are independently each an alkylene group having from 2 to about 4 carbon atoms; R', R 2 , R 4 , R 5 , R 7 , R 8 , and R 8 are independently each methyl or ethyl; R 6 is an unsubstituted alkylene group having from about 2 to about 4 carbon atoms or a substituted alkylene group having from about 2 to about 4 carbon atoms and containing a hydroxy group; X is an anion selected from halogen, methyl sulfate, sulfate, and nitrate; n represents the valency of the anion represented by X; and s in an integer equal to the number of anions required to maintain electronic neutrality.
