Partially Hydrolyzed Polyacrylamide
PHPA is short for partially hydrolyzed polyacrylamide,it's a kind of drilling mud additive.Can be used in both industrial and oil/gas drilling.Can be used in both fresh water and brines but requires high temperature.
Application in:shale stabilization,viscosities,friction reduction,fluid loss control and lubrication

PHPA Advantages:

It functions as an inhibitor by coating or encapsulating formation & cuttings.
It also restricts the interaction of water hydratable & dispersible shale's.
It can be used as a flocculent in clear water drilling.
It also provides inhibition properties to fresh water, sea water and also in presence of calcium ions.
High viscosity of this drilling fluid helps in better removal of cuttings from bore hole.
It is resistant to bacterial fermentation.

More Application Of PHPA

Certain types of polymers have been used successfully for many years in oil fields as drilling mud additives for viscosity modification shale inhibition/clay stabilization and fluid loss control. A wide range of products is available to suit the particular type of water based drilling mud system used by the operator to achieve the optimum performance. Each specific application is given below:
Well Drilling Mud Raw Materials: In oil field exploration and development and exploration of geology,water and coal,it is used as adhensive of well drilling mud raw materials,can improve the service life of drill bits,improve the drill speed and drilling footage,and reduce plug in replacing drill,and has prominent well slough preventing effect,and it can be used as fracturing fluid of oil fields or plugging agent of controlling profile and plugging water.
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+,Fe3+,Ca2+ and other ions,a part of high molecular compound is changed from linear shape into body shapes.The product is not wastesoluble to block ground layer gaps and topreven 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 multipoint adsorption of polymer formats to the crisscross membrane macromolecules,plays a role of enhancing the stability of borehole.
