Profile for Oil Drilling Mud Additives--polyacrylamide
The oil drilling mud additives that we can supply include anionic polyacrylamide and
guar gum powder
1.(PHPA)Anionic polyacrylamide used for oil drilling mud additive.
1)Product characteristics
White or yellow powder,non-toxic,non-corrosive,easily solubale in water,mainly used as a selective flocculant for
non-dispersed,low solid phase water-based drilling fluid.it can help to reduce water losses,improve drilling fluid
rheological properties and reduce the friction resistance as well.

3)Application
In oil exploitation, polyacrylamide is mainly used for drilling mud as well as Enhanced Oil Recovery, etc., which is
widely used in drilling,completion, cementing ,fracturing, enhanced oil recovery and other mining operations in the
oil field. SH’s products have been used successfully for many years as drilling mud additives for flocculant ,
dispersants, blocking agent , lubricants , fluid loss additive, and shale inhibition agent etc. With the continues
progress, SH devotes to develop the products with optimum performance to meet the increased requirement of
water based drilling fluid.
Flocculant
The polarity gene adsorbs the solid particles dispersed in water, bridges between the particles and formats the
large aggregates, sedimentation and separates of water, flocculates detritus and clay in drilling fluid.
Dispersant
In the drilling mud treatment, this product can improve the lubricity and stability of the mud to reduce the water loss,
prevent sticking effectively, increase drilling efficiency.
Blocking Agent
The product can generate cross linking under the effect of Al3+, Fe 3+, Ca2+ and other ions, a part of high molecular
compound is changed from linear shape into body shapes.The product is not watersoluble,and can be adsorbed on
the borehole to block ground layer gaps and to prevent the leakage of drilling fluid.
Lubricant
The product can be absorbed on the surface of metal or clay particles to form liquid film to change friction on the solid
surface into liquid frication, thereby lubricating drill bits and drills, lowering the mud cake frication coefficient, and
reducing underground accidents.
Fluid Loss Additive
The hydrolysis degree is higher, the hydration group on the molecular chain is more, the hydration is better, and it
changes from flocculant into fluid loss additive. Drilling mud should be treated to keep cake’s permeability as low
as possible in order to maintain a stable borehole and to minimize filtrate invasion, and damage to the pay zone.
Shale Inhibition Agent
The multi-point adsorption of polymer formats to the criss-cross membrane macromolecules, plays a role of
enhancing the stability of borehole.
2.Guar gum powder used for oil drilling mud additive.
Fast Hydration Guar Power is based on the guar gum, by further optimization of the purication, the dissolution rate of
the guar gum is much more enhanced. In a relatively short period of time, it can reach to the peak value of the viscosity.
This feature ensures the full use of the guar gum viscosity, making it easy to use, and at the same time to reduce the
cost and to improve the quality.
Applications
Fast Hydration Guar Power is design by our R&D Research and produced under our strict production procedure, which
is mainly used in the oil and the gas fracturing, the foodstuff and the Pharmaceutical & Health care field etc.
1) In Hydraulic Fracturing
The shale oil and gas extraction industries consume about 90% of the guar gum produced worldwide as it prevents oil
droplets from coalescing.
2) In Oil Field Drilling
It works in the petroleum industry as the additives for the aqueous and water / methanol based fracturing fluids, as the
water loss control, the viscosity control, the suspensions, the friction reduction or the mobility control, help to increase
the viscosity,to reduce the fluid loss and to decrease the fluid friction.
3) In Dairy Products
It can be used to maintain the same quality and texture after the sterilization in the yoghourt, the jelly and the sauce.
4) In Bakery
In the production of the bread and the cake etc, it could work as the dough improver, it can absorb the big cluster
structure water and prolong the shelf life of the product.
5) In healthcare
It contains galactomannan, which can improve the immunity, protect the gastrointestinal system, lower the blood
glucose and the insulin levels.
6) Pharmaceutical industry
It can work as the binder or as the disintegrator in tablets.
