摘要: Methods of reducing the permeability of a subterranean formation to aqueous-based fluids using a water-soluble relative permeability modifier that comprises a hydrophobically modified polymer, wherein the hydrophobically modified polymer is a reaction product of: a hydrophilic polymer that comprises a polymer selected from the group consisting of a polyvinylamine, a poly(vinylamine/vinyl alcohol), and an alkyl acrylate polymer; and, a hydrophobic compound comprising at least one alkyl chain having a carbon chain length between about 4 and about 22 carbons. The water-soluble relative permeability modifier may be placed within a subterranean drilling operation such that the water-soluble relative permeability modifier attaches onto surfaces within the subterranean formation to effect permeability of aqueous fluids.

摘要: An hydraulic shock absorber with progressive braking effect comprising a cylinder (1,2) full of fluid and a piston (3) sliding axially into said cylinder. The piston (3) divides into two sequential chambers (8) and (9) the cylinder compartment (1). In the extension and/or compression operation, the piston (3) slides in the cylinder causing the fluid to move from the lower chamber (9) to the upper chamber (8) and viceversa, through ports (10) and compression (16) and extension (12) valves, with regulated and progressive opening/closing, with passages with calibrated and/or variable geometry.
