Medium-high temperature anti-saline fluid loss agent XBA-201
Introduction
XBA-201 has two types：XBA-201L (liquid ) and XBA-201S (solid);
XBA-201 is a polymer product with AMPS and AM as monomers.
XBA-201’s applicable temperature is 30~120℃(BHCT).
XBA-201 is not retarded and benefited to cement strength development.
XBA-201 slurry system is stable and has good compatibility.
XBA-201 is applicable to semi-saturated brine.
XBA-201L only can be used through wet mixing.
XBA-201S could be used through wet or dry mixing.
XBA-201’s dosage need to be adjusted according to temperature, salinity and cementing requirements.
