What role does water-soluble fiber play in use?

Water-soluble fibers are commonly used as a component or form of temporary plug material in oilfield development, specifically as water-soluble temporary plugging agents. These water-soluble fiber plugging agents offer excellent water solubility and temporary plugging performance, effectively sealing off areas during oilfield operations.

For example, there is a product called CXZD-5, a water-soluble temporary plugging agent made of fibers and other materials, which boasts good performance and promising prospects. Additionally, there are other water-soluble temporary plugging agents like JX-2, commonly used in well sealing operations to enhance the efficiency and effectiveness of oilfield development.

In oilfield operations, water-soluble fiber temporary plugging agents can form sealing substances by dissolving in water, temporarily reducing formation permeability or plugging highly permeable oil layers, thereby achieving the purpose of adjusting formation pressure and controlling oil well leakage. Moreover, these temporary plugging agents are typically biodegradable or can be manually unsealed after use, leaving no long-term impact on the formation.

Please note that the specific composition, properties, and usage methods of water-soluble fiber plugging agents may vary by product. Therefore, it is essential to carefully read the product manual and consult with professionals before use.
