AU-30 Microcapsule Gel Breaking Agent
AU-30 is a new water-based fracturing fluid breaker. Through a special process
layer formed on the surface of ammonium persulfate in water to prevent the intrusion
of insulation cladding. Cladding on the broken plastic components play a role in
shielding, by fracturing the temperature, pressure injection pump, carrying sand
abrasion and the combined effect of crack closure, cladding rupture, releasing
broken plastic components, play a slow gel breaking effect. Made to ensure that
the fracturing fluid in the joints and sand-carrying the required viscosity, the
construction can improve the final after breaking the fracturing fluid gel water,
increase liquid water fracturing fluid flowback rate, reduce the formation fracturing
fluid residue on the and diversion crack damage, thereby effectively improving the
productivity of formation.
(1) Appearance: light yellow granules; diameter of 0.6 ~ 1.2mm.
(2) gel breaking component effective content:> 80%;
(3) Inclusion rate:> 95%;
(4) dissolved foreskin type: can slowly dissolve in the crude oil;
(5) release rate: <25% (80 ℃1h).
Breaker for the formation temperature of 50 ~ 120 ℃, maximum pressure of 60MPa
construction of water-based fracturing fluid construction. For different depth strata,
construction emissions, tiles and sand than the total fluid volume to determine the
amount of breaker, breaker concentration of 0.01 to 0.06%.
25kg plastic lined paper bags, should be stored in the cool air, the effective storage
period is one year.
