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).
