Method and composition for improving performance of aqueous and polymer based fluids at high temperatures |
摘要 |
The invention provides aqueous based well drilling and servicing fluids containing a polymer viscosifier with enhanced thermal stability provided by a diacid or diacid salt preferably having about two to about eight carbon atoms, such as, for example, sodium oxalate. The invention also provides a method of enhancing the thermal stability of aqueous based well drilling and servicing fluids containing a polymer viscosifer by adding diacid or diacid salt to the fluids.
