In this service, the 1,000 m Type Hydraulic Tester owned by Japan Nuclear Cycle Development Institute was improved for 1,500m hydraulic test. The test also improved on the quality of data and the efficiency of test. Main improved items are as follows. (1)The test depth was increased to 1,500m from 1,000m. (2)The inner diameters of main testing tubes were increased for sifting the targeted permeability to the higher permeability zone. (3)The continuous measuring function of pressure and temperature in both sides of test section were added. (4)The slide end type packers were adopted because of its excellent watertight quality, durability and pressure resistance. (5)The expansion and contraction of the upper and lower packer can be controlled individually, through the independent system for both packers. (6)The pump system that can provide stable flow control and deep draft water pumping was adopted. (7)The simultaneous analysis system was added. By the improvement on the above, the 1,000m Type Hydraulic Tester was remodeled for 1,500m and improved on the quality of data and the efficiency of test.
