Water Stop Packer For Permeability Testing In Geotechnical Engineering

Top Pressure Packer (Spherical)

Top Pressure Packer (Cylindrical)

Inflatable Or water Filled Single Packer

Inflatable Or Water Filled Double Packer

Top pressure packer is a type of single packer that uses the gravity of the drilling rig's oil cylinder to expand and stop water in the rubber section. The top pressure packer is mainly used for permeability testing in shallow hole geotechnical engineering,drill a section of the drill pipe and measure it. Double plug packers are mainly used for permeability testing in deep hole geotechnical engineering. After drilling the entire hole, testing is carried out in sections of 5 meters from top to bottom, saving time and effort, and improving work efficiency.
