Product Description
SMR is made from anionic starch ethers after special production treatment. It can be hydrated in cold water, not easy mildew, with high content of active ingredients. It can obviously improve fluids loss control, low effect to viscosity, anti-temperature and salt features. It is natural material and environment friendly, suitable for various environmental drilling fluid. It has high acid soluble rate and can protect the reservoir. Its recommend dosage is 3.0 – 7.0ppb.
