Nano Depressurization and augmented injection agent for low permeability oil field is a type of nanometer silicone material made by organic silicone as the precursor, using the surface decoration technology of normal position. This product has the strong performance of oleophilic and hydrophobic, and good dispersivity in these organic agents such as diesel oil,solvent oil,carbon tetrachlorixe and chlorofluoromethane and so on. At the same time, its hydrophobic surface has the organic functional group that can combine the silanol, so that this type of nanometer particle can adsorb on the surface of crevice rockcliff of sandstone forming the stable hydrophobic surface film, accordingly reducing the resistance of water flow greatly.
Water injection and oil displacement is the conventional oil exploitation method, in the operation of water injection well, the operation pressure of water injection pump and the water injection rate of water injection well decide the output and cost of oil exploitation. Through using this product, can reduce the water injection pressure effectively, increase water injection rate, thereby can impove the crude oil output and decrease the cost. Dispersing this product in the diesel oil by the density of 0.10%-0.15%(W/V), inject this product on water injection well with a series of preprocessing such as acid cleaning, closing the well for 24-48 hours, make sure the product can absorb the underground rock surface adequately; then using the clear water as the displacement and high duty water injection, then normal injection water, in such way completing once decreasing pressure and increase injection treatment. The valid period is 4-12 months normally.
Our company not only can supply the general product DBDS-W, but also can supply the special injection agent according to the customer’s requirement.
