As a multifunctional additive, polyacrylamide can be used in many places, especially in the oilfield drilling process for mud enhancer, stabilizer and sedimentation flocculation to improve the rheology of the mud; polyacrylamide pam product It can improve the size of suspended particles, increase the suspension power, and accelerate the filtration and separation of crude oil.
Injecting polyacrylamide into salt water during secondary oil recovery can improve the spraying ability of salt water and effectively extract crude oil from the porous rock surface. Adding polyacrylamide pam to the water-oil emulsion can significantly reduce the viscosity of the emulsion. Adding people to the oil storage tank can reduce the water content on the surface of the oil tank and reduce the cost of adoption. In oil exploitation, the viscosity of the injection water can be increased to avoid breakdown of the oil layer and increase the oil recovery rate.
It is used as a thickener in the third oil recovery to increase the oil displacement capacity and improve the recovery effect of the oil bed. In the oil field, the newer anionic and cationic polyacrylamide pam can be used to protect the injected groundwater from permeating and condensing and recovering crude oil from opening holes, improving the economy of oil well production, and controlling the influx of water into the oil layer.
In addition. PAM is also used as fracturing fluid additives, lubricants, drag reducers, etc. In oil field chemistry, polyacrylamide PAM is a multi-purpose additive, such as drilling fluids, well washing fluids, water injection and oil recovery, and enhanced oil recovery, etc., which all play an important role.
