(1)Drilling mud additivies
The polyacrylamide can be Used as drilling mud additives in oilfield exploration and development and geology,water conservacy and coal exploration.i can prolong the bit’s life,raise the drilling rate and drilling footage,reduce the time of exchange drills.it has abvious effect in avoiding well collapse.it can also be used as oilfield fracturing fluid and profiling water blocking agent.
(1)EOR(enhanced oil recovery)
It can adjust the rheology of water injection,increase the viscosity of fisplacing liquid,improve the spreading efficiency of liquid displacement ,bring down the water permeability in strata and keep water and oil to flow at a constant speed.it is mainly used in tertiary recovery of oilfields.injection of each ton of PAM products can help to gather 100-150 tons extra crude oil.
(2) Industrial wastewater treatment.
Especially for the treatment of wastewater containing suspendent particles which is coarse,high concentration and with positive charges and water’s PH value is neutral or alkaline.most effective for wastewater treatment of iron and steel plant,electroplate factory,metallurgy and coal washing.
(3) it can be used as Papermaking additives.
(4) Drinking water treatment.
Many water plants in China come from river water,which contains large sum of sediment and mineral,very turbid.after precipitation and filtration,it still can not meet the requirements.polyacrylamide is needed.water plants used to use inorganic polyacrylamides.but large additive amount is required which caused the increase of sludge volume,not effective.use anionic PAM polyacrylamides,with 1/50 additive amount that of inorganic polyacrylamides,several times and even dozens of times effectiveness obtained than that of inorganic polyacrylamides.for those organic polluted river water,better effectiveness can be achieved while mixed used together with cationic PAM.
(5)Can be used for caustic soda’s clarification.used as retention aid,filter aid,reinforcing agent for wet and dry paper.
(6)Clarifying agent in sugar refining industry.
(7)Additives and adhesives in aquatic product feedstuff.
(8)can be used for construction bored pile.
