| titleOfInvention | A high-strength temporary plugging agent capable of realizing seepage in the well zone and its preparation method |
| abstract | The invention provides a high-strength temporary plugging agent capable of realizing seepage in the well zone and a preparation method thereof. It is prepared by the following method in parts by weight: take hydrophilic nanomaterials and evenly disperse them in a solvent, and then add glycerol allyl Ether monomer, after stirring or sonicating for 0.5-3h, add acrylamide monomer, stir to dissolve it, and add N,N-methylene acrylamide, acrylate compound and The initiator continues to react for 5-12 hours, and after the reaction is completed, it is dried to obtain the product. The high-strength temporary plugging agent capable of realizing seepage in the well zone of the present invention has a high plugging rate, which can reach more than 96%; a high plugging removal rate, which can reach more than 81%, and the residual condensation after the final plugging removal With less glue, it has less impact on the formation. At the same time, it has higher plugging strength and wider application range, and can be used for seepage volume fracturing in well zones. |
