Permeability Double Packer Rock Test/Permeability Rock Lugeon Test Equipment
- Description
- Inquiry
The Lugeon test, sometimes call also Packer test, is an in-situ testing method widely used to estimate the avarage hydraulic conductivity of rock mass. It is indeed In situ test of formation permeability performed by measuring the volume of water taken in a section of test hole when the interval is pressurized at given pressure (10 bars -150 psi). It is used primarily in variably permeable formations under evaluation of fracturating .
Deployment and operation is simple. The wireline permeability packer assemble is deployed down the drill rods until the bit seating sub lands on the drill rod bit. With the top seal assembly (tighthead) tightened, the packers are inflated and water is then pumped through the tighthead down the rods, through the packers and into the formation.
Main technical parameters:
Sealing hole diameter: 30-200mm (can be processed according to user requirements)
Working pressure :1-8MPa (can be processed according to user needs)
Work flow rate: 3-4.5 tons of grouting per hour
Sealing depth: 1-8000m
