SPNH 钻井液防流失添加剂
Product introduction
As drilling depth continues to increase, drilling fluids are prone to problems such as increased viscosity, out-of-control rheological properties, and flocculation of solid particles in high-temperature environments. This not only increases circulation pressure, but may also affect wellbore stability and drilling efficiency. In order to ensure that the drilling fluid maintains stable performance under high temperature conditions, it is usually necessary to add treatment agents with excellent viscosity reduction and rheology adjustment capabilities.
Lignite resin (SPNH) is a high-performance water-based drilling fluid treatment agent with good viscosity reduction, dispersion and rheology adjustment capabilities. It can effectively control the viscosity growth of drilling fluid under high temperature conditions, improve mud flow properties, reduce filter loss, and improve the salt, calcium and pollution resistance of drilling fluids.
