Test line for rock permeability testing - has measurement bells and packers on tube sections with connecting lines to earth's surface

摘要

The test line consists of tube sections (4) connected together and with test bells (3) and packers (5) mounted on alternate sections at selectable distances. The bells and packers are connected to lines (9,10) leading to the Earth's surface to enable indication of measurement values or for their operation. The measurement bells are open at the bottom and can be permanently or removably mounted on the tube sections. USE/ADVANTAGE - For investigation of organic and inorganic natural resources underground. Enables simple permeability testing of selectable horizontal rock strata.
