| titleOfInvention | A kind of elastic gel water shutoff agent and preparation method thereof |
| abstract | The present invention relates to a kind of elastic gel water shutoff agents and preparation method thereof.Mainly solving the problems, such as existing selective water shutoff agent, there are the big plugging effect of ground viscosity is poor.It is characterized by: its component and proportion it is as follows by weight percentage: acrylamide monomer 2-5%, promote jelly 5-15%, polymerization inhibitor 0.05-0.15%, colloid stabilizer 0.3-0.6%, crosslinking agent 0.3-0.6%, retarder 0.2-1.0%, initiator 0.2-1.0%, intercalating agent 0.2-0.5%, remaining be water；The present invention also provides a kind of preparation methods of elastic gel water shutoff agent, and first respectively by polymerization inhibitor hydroquinone monomethyl ether with 45-55 DEG C of hot water dissolving, initiator sodium peroxydisulfate is dissolved with clear water；Then after acrylamide monomer, rush jelly, colloid stabilizer, crosslinking agent, retarder, intercalating agent being successively added to the water dissolution in proportion, the polymerization inhibitor dissolved is added, is eventually adding initiator, product is made.The elastic gel water shutoff agent, ground viscosity is small, and gel strength is high, and colloidal stability is good, and closure validity period is long, and plugging effect is good. |
