| titleOfInvention | Hybrid gel particle while-drilling plugging agent and preparation method thereof |
| abstract | The invention provides a hybrid gel particle while-drilling plugging agent and a preparation method thereof, wherein the plugging agent is prepared from the following raw materials in parts by mass: 20-35 parts of reactive monomer, 1.0-3.0 parts of cross-linking agent, 0.3-0.5 part of initiator, 3.0-5.0 parts of silane coupling agent and 0.5-2.0 parts of nano-scale rigid particles; the reactive monomer is a combination of three or more of methacrylamide, hydroxyethyl methacrylate, lauryl acrylate, tert-butyl methacrylate, dibutyl adipate, sodium p-styrene sulfonate, vinyl benzene sulfonic acid or divinylbenzene; the nano-scale rigid particles are one or a combination of more than two of nano calcium carbonate, nano silicon dioxide, talcum powder or wollastonite powder. The gel particle plugging agent prepared by the invention has the advantages of strong toughness, high temperature resistance, strong pressure bearing capacity at high temperature, good plugging effect and the like. |
