Specifications
1. CELLOPABCTM Polyanionic Cellulose (PAC)
CELLOPABCTM PAC is an fluid loss reducer for stabilizing the shale, divided in two different models one of which is PAC—HV having high molecular weight and thickening ability, the other is PAC—LV with low molecular weight and without thickening ability.
Product Description: free flowing white or off-white powder
Chemical Nature: Polyanionic Cellulose
Physical and chemical properties
Packing density: 0.65-0.80g/cm³
Solubility in water: soluble
Temperature resistance: stable up to 120℃
Moisture: ≤10%
pH(1% solution): 6.5—8.5
Degree of Substitution (DS): ≥0.90
Characteristic
u Effectively control the mud viscosity and fluid loss by the uniform distribution of substitution and high degree of substitution, excellent transparency, prominent resistance to temperature and bivalent ion.
u Exhibit excellent compatible with fresh and sea water, and more efficiency in saturated salt and magnesium-containing brine, higher resistance to calcium ion as compared to the traditional CMC.
u PAC—HV acts as thickening agent and renders the shear thinning fluid an eminent ratio of yp to pv.
u PAC—LV plays a special role in the weighted drilling fluid, aiding in controlling the gel concentration and improving the quality of mud cake.
u Impart rheological property to mud, inhibiting the dispersal and inflation of clay and shale in high salt medium, controlling the contamination of wellbore wall.
u Stabilize the soft soil, preventing the wellbore from being collapsed by the elevation of water level
u Slow down the accumulation of cutting in the drilling fluid as drilling through the rock formation.
u Decrease the turbulence in the drilling pipe, keeping the pressure loss of circulation system at minimum.
u Enhance the yield of mud, reduce fluid loss, and stabilize foam.
CELLOPABCTM PAC is an excellent drilling, work-over or completion fluid, as well as an effective fracturing fluid.
CELLOPABCTM PAC strictly accords with these standards as followed:
API and OCMA Specification for Drilling Fluid Materials
GB/T5005-2010 Drilling Fluid Materials Specification
Usage method
Slowly and evenly pumped in at the rate of 15—20min per bag to avoid forming large glue granule .
The additive amount is determined to a large extent by the suspended solid adsorbed on the mud particles surface, in general, additive amount of PAC—HV is 2.0-5.0kg/m3, PAC—LV is 5.0-7.0kg/m3.
