ZD-LCA Lost Circulation Additive

This product is a gel polymer with strong water absorption and expansion, and has the characteristics of delayed expansion, which can ensure that the granular material has enough time to enter the downhole leakage layer and continue to expand. In addition, by introducing temperature and salt resistant groups and chemical coupling agents into the molecular chain, the polymer is connected to the temperature resistant material as a whole, thus making it have good strength, toughness, and thermal stability under high temperature and high salt conditions. The particle size can be adjusted according to on-site needs, suitable for sealing large and small cracks and melt holes under various conditions. This product has good compatibility with various water-based drilling fluids, which can achieve good plugging effect and effectively improve the pressure bearing capacity of the formation. The dosage depends on the specific situation.
