Fluid loss Additive for drilling fluid XBA-20S
Introduction
XBA-20S is a modified cellulose fluid loss agent and has the function of coating agents, inhibitors, at the same time. The drilling fluid with XBA-20S has good fluid loss, inhibition, high temperature resistance and salt resistance. XBA-20S is suitable for the drilling work of deep wells, high temperature wells, brine wells and offshore wells. XBA-20S can inhibit the dispersion and swelling of clay and shale in high salt medium, retard the time for swelling and dispersion of clay hydration.
Advantages
High temperature resistance (150°C). Good salt performance. Low filtration loss. Good slurry stability.
Indicators
API water loss (150°C, 0.69 MPa): ≤15 Ml. Apparent viscosity: ≤ 20 Pa.
