| titleOfInvention | Drilling fluid GEL USED FOR PLUGGING WELL LOST CIRCULATION and preparation method thereof |
| abstract | The invention discloses drilling fluid GEL USED FOR PLUGGING WELL LOST CIRCULATIONs and preparation method thereof, belong to drilling fluid additive agent field.The sealing agent is polymerize to obtain by following components, based on parts by weight, the component includes: 25~35 parts of acrylamide, 20~30 parts of sodium allylsulfonate, 45~55 parts of distilled water, dimethyl -3~7 parts of ethyl acrylate-cetyl ammonium bromide, N, 3~8 parts of N- methylene bisacrylamide acid amide, 0.5~1.5 part of initiator.This product overcomes the disadvantages of poor conventional GPC sealing agent Anti-temperature difference, salt resistance, poor toughness, has good temperature resistance, resistance to compression and thermal stability, adapts to different aperture, fractured leakage stratum, is a kind of completely new polymer gel sealing agent. |
