Acid gelling agent
DESCRIPTION
SMLZ-AGA-306 is a white powder which dispersed and dissolved in water and acid, it is a copolymer of cationic monomer& acrylamide.
APPLICATION&ADVANTAGE
It is used for carbonate reservoir( Acid/rock reaction), it can viscosify effectively to 20%HCL & 25%HCL, has good temperature & shear resistance and can be used in acid system of 180℃/356F reservoir.
- It has good retarding performance, test showed that the retarding rate of 0.8% SMLZ-AGA-306+20%HCL high-temp.gel is more than 90% compared with white acid.
- It has excellent fluid loss reducing property, SMLZ-AGA-306 high temperature gel is of perfect rheological function, effectively reduces the formation of fluid loss
- It has good compatibility, can mix with inhibitor, demulsifier, iron ion stabilizer, anti-swelling agent, soluble to wateror acid.
- It has good rheological & thermal stability with below test data:
- 0.8% SMLZ-AGA-306+20%HCl gel system is for 140-160℃/284-320F reservoir, when the shear rate is 170s-, the viscosity can reach 40-60mPa.s at 25℃/77F, 30-35mPa.s at 90℃/194F, and 20-30mPa.s at 120℃/248F respectively(Chart1)
2. 1% SMLZ-AGA-306+20%HCl gel system is for 160-180℃/320-356F reservoir, when the shear rate is 170s-, the viscosity can reach 50-70mPa.s at 25℃/77F, 45-50mPa.s at 120℃/248F, and 20-30mPa.s at 160℃/320F respectively(Chart 2)
