| titleOfInvention | A kind of cementing properties GEL USED FOR PLUGGING WELL LOST CIRCULATION and preparation method thereof |
| abstract | Open a kind of cementing properties GEL USED FOR PLUGGING WELL LOST CIRCULATION of the present invention and preparation method thereof, belong to technical field of oilfield chemistry, carried out polycondensation by sulfonated melamine, hydrophilic monomer, cationic monomer, initiator, pH value regulator and water and copolyreaction obtains, its beneficial effect is the introduction of the heat-resist triazine ring heterocycle structure contained by sulfonated melamine, improve heat-resisting property, and containing substantial amounts of hydroxyl, carboxyl, amino isoreactivity group in cementing properties loss circulation material, can react further at the formation temperature, there is cementation, it is possible to form stronger blocking. |
