A, product introduction
CELLOPABCTM polyanionic cellulose (PAC) is to maintain the stability of the shale filter is out of control agents, there are two types of specifications: PAC HV and PAC LV. PAC HV is the polymer chain, can viscosify, PAC - LV is low molecular chains, without thickening.
Second, the main physical and chemical properties
The shape of
White or light yellow liquid powder
Packing density
0.65 ~ 0.80 g/cm after
Water soluble
dissolve
The temperature
120 ℃ stability
moisture
10% or less
Aqueous solution pH (1%)
6.5 ~ 8.5
Degree of substitution (DS)
0.90 or higher
1. The degree of substitution is high, the molecules replace uniformity, high transparency, good heat resistance and bivalent ions resistance performance is good, can control the viscosity and water fluid loss.
2. Suitable for in seawater or freshwater system as the fluid loss agent, CMC, compared with the tradition is more effective in brine saturated brine and magnesium, calcium resistance stronger.
4. The PAC - LV special role in the weighted mud system. Its mild dispersion effect can assist gel concentration control and improvement of the quality of filter cake.
5. Use the product configuration of mud has rheological property, can be suppressed in high salt medium clay and shale dispersion and swell, making wall pollution under control.
6. Stability of soft soil structure, prevent collapse caused by the rising water wall.
7. The well drill through the rockface, slow accumulation of drilling cuttings solid in the mud.
8. Inhibition of turbulence intensity in the drill pipe, keep return system minimal pressure loss.
9. Can improve the mud slurry amount, reduce the amount of filtration, stable slurry bubble.
CELLOPABCTM PAC is fine mud drilling fluid and drilling repair fluid, fracturing fluid is efficient.
Four, CELLOPABCTM PAC application conforms to the following standards:
1. OCMA drilling fluid material specification and API standards.
2. The standard GB/T5005-2010 drilling fluid materials.

Six, the processing method
1. The PAC to prevent a grand colloidal particles per bag of 15 ~ 0 minutes slow to pump into the flat.
2. The PAC addition amount to a large extent by the adsorption on the surface of the mud particles, suspended solid of the specific circumstances. Generally add quantity for, PAC - HV: 2 ~ 5 kg/m3, PAC - LV: 5 ~ 7 kg/m3.
