PolyTSHCHR reagent for drilling fluids

PolyTSHCHR is a composite reagent for treatment of freshwater, saline and clay-free drilling fluids to obtain aerated fluids of reduced density and construct wells in sections prone to lost returns.
PolyTSHCHR-1 reagent is designed for preparation of clay-free drilling fluids.
PolyTSHCHR-2 reagent is designed for treatment of freshwater and saline clay suspensions.

Application

PolyTSHCHR reagent reduces drilling fluid density, facilitates foam formation and stabilization. When applied, the reagent ensures reduction in the density of the flush liquid to 0.9 g/cm? and below, thus reducing the probability of lost return when passing fissured and complicated sections. In addition to its foam-forming action, PolyTSHCHR is an effective colmatant, which also helps prevent lost returns.

 

Treatment

When preparing a clay-free drilling fluid, PolyTSHCHR consumption is ~ 70-100 kg per 1m? of fresh or saline water. Reagent consumption when used as an additive in clay fluid is ~10-30 kg per 1m?.

 

Packaging

PolyTSHCHR reagent for drilling fluids is packed into 20 kg polypropylene bags with polyethylene liner.
