Modified starch for drilling fluid DFD-140 is a water-soluble product made by carefully selected starch, reaction with the active substance with a specific functional group under catalytic conditions. DFD-140 modified in the molecular chain to increase its resistance to temperature and salt. So that this product can be used in a higher formation temperature deep wells. With no degradation, fermentation, little impact on the rheological properties of drilling fluid, this product is a cheap alternative of CMC or other similar products.
This product has efforts to reduce fluid loss, can reduce the water loss of fresh water and salt water. Maximum resistance to temperature about 140 ℃, does not affect the drilling fluid flow, tackifier; fermentation, not easily degradable, good compatibility with other treatment agents; non-toxic, do not pollute the environment.
