Question: Why does oil drilling fluid use polyacrylamide powder instead of emulsion?

answer:

The choice to use polyacrylamide powder instead of emulsion in oil drilling fluids is related to factors such as usage requirements and convenience, such as:

1️⃣ High-temperature stability: Petroleum drilling fluids will be affected by high temperatures during the drilling process, and polyacrylamide powder can maintain stability in high-temperature environments and play its role in thickening and rheology control.

2️⃣ Convenience: Polyacrylamide powder is easier to store, transport and use than emulsion. Emulsions are generally composed of liquid and polymer particle suspension systems and require special equipment for stirring and stability control, while polyacrylamide in powder form is more convenient to supply and operate.

3️⃣ Flexibility in ratio adjustment: Polyacrylamide in powder form can be flexibly adjusted according to actual needs to meet different well conditions and process requirements. Emulsions are more difficult to adjust accurately on site.
