Detailed Product Description

  

Attapulgite drilling fluids API grade & OCMA grade.
Attapulgite drilling fluids is a kind of anti-salt clay used as drilling fluids based on good quality attapulgite clay. It is applicable to geological drilling, marine drilling and geological drilling in salt containing area. It has good thermal stability and salt resistant property, reduce the rate of useless wells while using it to protect the wall of wells, save barite powder, the drilling efficiency is improved and the cost is cut down.

Performance and Applications
1. The product has good colloidal and suspending properties, is suitable to be used as drilling mud under different geological conditions.
2. Because of good thermal stability, it shows no flocculation and dilution under high temperature conditions, therefore, it is applicable to deep well drilling and terrestrial heat drilling.
3. Its salt resistant ability makes it free from being affected by electrolytes, thus it can still be in mud form even in saturated brine. It is suitable for marine and salty stratum drilling.
