Water Well Logging Equipment 50HZ Borehole Geophysical Logging Equipment
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.
