Water Well Logging Equipment Borehole Geophysical Logging Equipment
Borehole Geophysical Logging Equipment is designed for the convenience of field work and can connect
various logging probe pipes. Due to the use of a series of advanced
technologies, the system has changed the cumbersome equipment of a
subsurface probe corresponding to a surface instrument into a light
way that can connect various logging probes to a surface
instrument, and also includes the functions of depth measurement to
supply power to the subsurface instrument. The instrument has the
advantages of light weight, simple operation and maintenance, many
kinds of underground exploration pipe, earthquake resistance,
temperature resistance, humidity resistance and high reliability.
Application
GDQ-2D Logging System can measure than 20 kinds parameters, covered
with metal ore, coal, oil field, radioactive, hydrology, and other
areas of the various user's requirements, with great
cost-effective.
Feature
1.Standardization and modularity:The benefits of standardization
and modularity Product is excellent in products' consistency ,
maintainability and reliability. It is convenient to operate and
maintain. The accessories are 100 percent universal and can be
expanded at any time.
2.Fully underground digital and measurement's signal
transmission:All the signals from the underground probe are
converted by A/D and sent to the ground after being encoded. The
underground probe is a two-way street communication.
3.Oversampling technology to obtain the most formation
information:The oversampling amount increases with the decrease of
the logging speed, and over sampling ensures the need for digital
filtering, enhancing spatial resolution and screening useful
information.
4.Small size of the underground probe with high pressure:GDQ-2D
Logging System probe is almost diameter Φ40 and Φ50 mm, the
appearance of length 1000~1500mm size. The probe is made of
stainless steel. Resistance to 20~40 MPa water pressure,
temperature of 70 ~ 90 ℃. Special orders can be 60 MPa water
pressure resistance, temperature 120 ℃ resistance.
