Drilling Grade Polyanioic Cellulose Pac Hv - Chinaprice: contact company for price
effectively reduces the filtration rate of many water-based
oil and gas drilling fluids and may also be used to increase
and stabilize viscosity to improve hole cleaning and
suspension properties in a wide variety of fluid
PAC R is a cost-effective additive to reduce API filtration
rate of many water based drilling fluids including
freshwater, seawater, saturated saltwater and solids-free
brines, native mud, flocculated mud, inhibited mud and
4. PAC R increases and stabilizes viscosity to improve
rheology, wellhole cleaning and suspension property by
coating and encapsulating cuttings and solids of drilling
5. PAC R is effective over a wide range of pH environments.
It lubricates solids in the system, improve wallcake
characteristics and reduces the potential for stuck pipe.
6.Petroleum grade Product features:
1), high degree of substitution, good uniformity of
2), high transparency, viscosity and water loss can be
3), suitable for fresh water, sea water, saturated brine
4), stabilize soft soil structure, prevent collapse of wall
of a well .
5), can improve mud-making volum, reduce filteration loss .
6), has excellent performance in drilling of oil .
HV-PAC, white and light yellow powder, belongs to high
molecular polyanionic cellulose. It canbe directly added
into various water base muds and its common dosage is
1, High degree of substitution, good uniformity of
2, high transparency, viscosity and water loss can be
3, suitable for fresh water, sea water, saturated brine
4, stabilize soft soil structure, prevent collapse of wall
5, can improve mud-making volum, reduce filteration loss .
6, has excellent performance in drilling of oil .
1.Polyanionic cellulose application in the drilling fluid.
PAC for fluid loss inhibitors and water is ideal, PAC fluid
mud can be prepared in high salt medium clay and shale
inhibition dispersion and expansion of the shaft so that the
pollution under control.
2, .PAC workover fluid in the application.
PAC prepared using workover fluid is a low-solid-phase,
and not because of the solid layer and the blocking of the
infiltration capacity of the production would not be harmful
to the production floor; and the loss of low water, so that
production level to reduce the amount of water, and access
to water emulsion will be formed by blocking phenomenon
PAC prepared using workover fluid to provide hydraulic
workover other advantages not available.
Production level to protect against permanent damage;
Clean the hole with a carrying capacity, and the
maintenance of boreholes to reduce the workload;
Resistance to water and sediment have the ability to
infiltrate and few foaming;
Can be stored or transferred between the wells and wells,
and workover fluid mud than the average and low cost.
3. PAC in the fracturing fluid applications.
PAC prepared by fracturing fluid capability 2% KCI
solution (the preparation of the fracturing fluid must be
added) and dissolution performance, ease of use, you can
Site preparation, and gel fast, strong ability to carry
sand. Osmotic pressure in the formation of low
It can improve the rheological properties, help to
effectively encapsulate drilling cuts, and inhibit mud
yielded by soil.
It has a strong capability of resisting salt, calcium and
magnesium. And it can be applied in fresh water, seawater,
saturated salt water and saltwater for completion drilling
It can be applied in super-deep wells because it can stand
It can effectively inhibit shale being dispersed and
stabilize the borehole.
It can match with other agents well.
It can effectively reduce viscosity and filtration loss and
its dosage is few.
It can be applied in various drilling fluids for fresh
water, salt water, saturated water and seawater.
It has a thermal stablility with standing 150℃.
It can match with other agents so that it can be applied in
various water base completion fluids.
It is not toxic and biodegradable, which helps to protect
