| titleOfInvention | Oil/gas Well cement polymkeric substance wide temperate zone retardant and preparation method thereof |
| abstract | The invention discloses Oil/gas Well cement polymkeric substance wide temperate zone retardant and preparation method thereof, the preparation process of this retardant is as follows: (1) is by methylene-succinic acid, acrylamide, sodium p styrene sulfonate deionized water dissolving mixing, the pH of regulator solution is 6 ~ 7, the mass ratio of methylene-succinic acid, acrylamide, sodium p styrene sulfonate is 1 ~ 2:2 ~ 4:2 ~ 4, and the mass concentration that in solution, monomer is total is 10 ~ 20%; (2) above-mentioned mixing solutions is warming up to 40 ~ 60 DEG C, adds initiator, in nitrogen environment, carry out polyreaction 4 ~ 6h, obtain polymers soln; (3) with dehydrated alcohol extraction, dry, grind to form powder.This retardant effectively can avoid the generation of oil and gas well mud extra retarded set or deficient retardation phenomenon in cold zone, high-temperature zone effectively can extend the thickening time of oil and gas well mud, can with multiple admixture system compatibility, do not affect the over-all properties of grout, there are wide market outlook. |
