Anionic Polyacrylamide Emulsion In Drilling Fluid Polymer And Drilling Mud Additives

Acid Fracturing Emulsion

This product has very good heat resistance and small change of viscosity-temperature property below 120 ºC.

Beside thickening, the acid compounded with thickening agent has the advantages of below:

1. Easy to make on spot, low concerntration has good thickening effect;
2. Salt tolerance and heat resistance. The product is cationic polymer, which could prevent the swell of clay and migration of particle;
3. Good drainage performance;
4. Good compatility with other addtive like inhibiter, Fe stabilizer, clean up additive and etc in the acidizing fluid;
5. Reduce the acid rock reaction rate and acid loss rate, increase the reaction radius of acid fluid.

How Does It Work in Drilling Fluids?

1. Viscosity Control: Polyacrylamide helps to control the viscosity (thickness) of drilling fluids. This is important because it ensures that the drilling fluid can carry rock cuttings to the surface efficiently.
2. Stabilization: It stabilizes the drilling fluid by preventing the formation of large clumps, keeping the fluid smooth and consistent.
3. Water Loss Control: Polyacrylamide reduces water loss from the drilling fluid into the surrounding rock formations, which helps maintain the fluid’s properties and protects the wellbore.
4. Shale Inhibition: It helps prevent the swelling and disintegration of shale formations encountered during drilling, which can otherwise cause problems like sticking of the drill pipe.

Benefits

• Improved Drilling Efficiency: By stabilizing the drilling fluid, polyacrylamide helps in more efficient drilling operations.
• Reduced Problems: It minimizes issues such as stuck pipes and formation damage, leading to smoother and safer drilling.
• Cost-Effective: Using polyacrylamide can reduce overall drilling costs by improving fluid performance and reducing downtime.

Fracturing fluid

In oil and gas field fracturing operation, polyacrylamide is used as thickening agent for fracturing fluid to increase the viscosity of the fracturing fluid, so that it can bring fracturing sand into the fracture more effectively. And keep the fracture open to increase oil and gas production.
