It has excellent anti-collapse, fluid loss reduction, and dispersion stability properties, can adsorb and encapsulate clay particles, inhibit formation hydration expansion, and stabilise the wellbore; effectively optimises filter cake quality, reduces filtrate invasion into the formation, and has good temperature and salt resistance. It is highly compatible, suitable for various water-based drilling fluids, applicable to formations prone to collapse and gelation, prevents narrowing and collapse, and stabilises mud performance
