The workover fluid formulated with PAC provides advantages that other workover fluids do not have;
- Protect the production layer from permanent damage;
- It has the carrying ability to clean the wellbore, and the workload of maintaining the wellbore is reduced;
- It has the ability to resist the infiltration of water and sediment, and it rarely foams;
- It can be stored or transferred from well to well, and the cost is lower than ordinary mud workover fluid;
- The fracturing fluid prepared with PAC can withstand 2% KCL solution (must be added when preparing the fracturing fluid) and has good solubility. It is easy to use, can be prepared on site, and has fast gel forming speed and strong sand carrying capacity. Used in formations with low osmotic pressure, its fracturing effect is more excellent
