When selecting and using PAC-polyanionic cellulose fracturing fluid, you need to pay attention to the following points:

Adaptability and Compatibility: Select PAC products suitable for specific application scenarios to ensure their compatibility with other fracturing fluid components.

Viscosity and stability: PAC has high viscosity and high stability, which can provide good proppant carrying capacity and prolong the effective period of fracturing. Choose a PAC product with the proper viscosity and stability to meet the demands of your fracturing operation.

Thickening ability: PAC can be used as a thickener to increase the viscosity of fracturing fluid. Select PAC products with proper thickening ability to ensure that the thickening effect of fracturing fluid meets the requirements.

Suspension ability: PAC has good suspension ability and can maintain the uniform distribution of proppant in fracturing fluid. Choose PAC products with good suspending ability to ensure the suspension and delivery of proppant.

Shear resistance: During the fracturing process, the fracturing fluid needs to withstand high shear force. Choose PAC products with good shear resistance to ensure that the viscosity of the fracturing fluid can remain relatively stable under high shear conditions.

Compatibility: Ensure that the selected PAC product has good compatibility with other fracturing fluid components to avoid possible chemical reactions or incompatibility issues.

Quality Control: Before use, conduct quality inspection and control on selected PAC products to ensure that they meet relevant quality standards and requirements.

In short, when selecting and using PAC-polyanionic cellulose fracturing fluid, the above points need to be paid attention to to ensure the effectiveness and safety of fracturing operations. At the same time, it should be selected and optimized according to the specific oilfield conditions and fracturing requirements to achieve the best fracturing effect.
