| titleOfInvention | A kind of high temperature resistant antipollution well cementation insulating liquid and preparation method thereof |
| abstract | The invention discloses a kind of high temperature resistant antipollution well cementation insulating liquid and preparation method thereof, the insulating liquid is made up of by weight following each component：100 parts of clear water, 1~3 portion of suspension stabilizer, 0.5~2 part of tackifier, 0.5~1.5 part of diluent, 0.2~2 part carries viscous extracting and cutting agent, 0.02~0.1 part of antioxidant, 2~30 parts of anti-pollutants, 30~220 parts of heavy weight additives, 0.1~1 part of pH adjusting agent, 0.1~0.5 part of defoamer.The tackifier are that at 40~60 DEG C graft copolymer caused by radical polymerization occurs for hydroxyethyl cellulose and sodium p styrene sulfonate.The anti-pollutant is itaconic acid, acrylamide, the sodium p styrene sulfonate copolymer that 4~6h of polymerisation is obtained in 40~60 DEG C of nitrogen environment.The insulating liquid temperature limit is wider, solves the pollution problem of slurry, meets engine request, and its preparation method principle is reliable, easy to operate, has wide market application foreground. |
