Lignite resin is a multi-component copolymer drilling fluid fluid loss agent copolymerized by nitrohumic acid, sulfomethyl phenolic resin, etc. It has a certain viscosity reducing effect and has good temperature and salt resistance. It is suitable for Suitable for various freshwater river brine drilling fluid systems.

Lignite resin has the functions of high temperature resistance, salt resistance, water loss reduction, collapse prevention, and lubrication. It can form a thin and tough mud cake on the well wall, achieve good lubrication effect and maintain good rheology. Therefore, it can be used in deep wells where the formation temperature is relatively high, and its temperature resistance can reach 200°C. It can significantly reduce the water loss of fresh water, salt water and salt slurry. It is non-toxic and does not pollute the environment. It can be added directly to various water-based drilling fluid systems. The general dosage is 2.0~4.0%.
