Product Detail

Product Description

TSG is a kind of special technology modified natural polysaccharide polymer which possesses various glycosyl construction unit. The amine monomers are inserted into the molecular chains, so chemical activity of drilling fluid is low and the stability of shale is enhanced. The applications home and abroad show that: TSG has good properties of forming film, high-temperature resistance, shale inhibition and salt resistance. It is non-toxic and can protects oil and gas reservoirs. The recommended dosage is 3.0 -5.0% (v/v).

Features

  • Form semipermeable membrane on the interface to enhance borehole stability. It’s especially suitable for water sensitivity formation (mud stone formation, salt rock formation and soft mud stone formation and other complex formation).
  • Good lubricating property and can be applied to horizontal wells, high angle deviated wells and other complex wells.
  • Excellent salt contamination resistance.
  • Perform reasonable filtration control property well up to 120℃.
  • Protect oil and gas reservoirs.
  • Non-toxic, biodegradable, suitable for building environment friendly drilling fluid.
