Multi-Scenario Application Well Logging Equipment With Resistivity Logging Probe Density Logging Probe

Product Description

Geophysical GDQ-2D borehole logging equipment accurately identifies freshwater pay zones in groundwater exploration at depths of 100 to 3000 meters through logs. Equipped with a basic combination of gamma and electrical logging probes, the borehole logging equipment can accurately identify freshwater formations, accurately map their thickness, and reveal clay lenses or saltwater intrusion. Its resistivity probes measure gradient resistivity, normal resistivity, and SP simultaneously, providing more comprehensive formation information. The borehole logging equipment is suitable for drilling bare casing holes and operating in water or mud environment. It is light in weight, simple in operation and maintenance, connected pipe and wire, earthquake-resistant to temperature and moisture, and has high reliability. The device can measure more than 20 parameters and is widely used in metal ore, coal, oil field, radioactivity, hydrology and other fields.

System composition
Ground system: It is the control center and data processing center of the entire logging CNC equipment, usually installed in the ground control room of the logging vehicle or well site. It mainly includes computer system, operation console, data storage device, communication interface, etc. The ground system is responsible for sending control instructions to the downhole instrument, receiving data uploaded by the downhole instrument, and processing, displaying, storing and transmitting the data in real time.
Downhole instrument: It is a combination of sensors directly lowered into the wellbore to measure the physical parameters of the formation. According to different measurement functions, downhole instruments can be divided into many types, such as resistivity logging instrument, acoustic logging instrument, density logging instrument, neutron logging instrument, etc. These downhole instruments usually have high-precision sensors and electronic circuits, which can accurately measure and collect various physical signals under harsh environmental conditions underground, and convert them into digital signals and transmit them to the ground system through cables.
Cable transmission system: It is mainly composed of logging cable, winch and cable bridle. Logging cable is a key component connecting the ground system and downhole instruments. It not only bears the weight of downhole instruments, but also transmits power, control signals and data signals between downhole instruments and ground systems. The winch is used to control the lifting and lowering of the logging cable so that the downhole instrument can measure at different depths in the wellbore. The cable bridle is a special connector that connects the logging cable and the downhole instrument. It has functions such as sealing, insulation and mechanical connection to ensure reliable connection and signal transmission between the downhole instrument and the cable.

Features
High-precision measurement: Using advanced sensor technology and signal processing algorithms, it can perform high-precision measurements on physical parameters such as resistivity, acoustic wave time difference, density, and neutron porosity of downhole formations. The measurement accuracy can reach several decimal places or even higher, providing accurate data support for geological analysis and reservoir evaluation.
Multiple measurement modes: With multiple measurement modes and functions, different downhole instrument combinations and measurement parameters can be flexibly selected according to different geological conditions and exploration needs to achieve comprehensive and detailed measurements of downhole formations. For example, when conducting conventional logging, multiple parameters such as resistivity, acoustic waves, and density can be measured simultaneously; when conducting special logging, such as imaging logging and nuclear magnetic resonance logging, more detailed and intuitive formation information can be obtained.
Real-time data transmission and processing: Through a high-speed cable transmission system, the data measured by downhole instruments can be transmitted to the ground system in real time, and processed and displayed in real time in the ground system. Geological engineers and logging operators can observe the changes in physical parameters of downhole formations in real time on site, and adjust measurement plans and parameters in time to ensure the smooth progress of logging work and data quality.
Data storage and management: Equipped with large-capacity data storage devices, it can store a large amount of data obtained during the logging process for a long time and stably. At the same time, it has perfect data management functions, which can classify, retrieve, query and back up the stored data, and facilitate subsequent data processing, analysis and interpretation.
Remote monitoring and diagnosis: Some advanced logging CNC equipment also has remote monitoring and diagnosis functions. Through network communication technology, the well logging data and equipment status information of the well site can be transmitted to the remote control center in real time. Technical experts can monitor and guide the logging process in real time remotely, and solve problems that arise during the logging process in a timely manner. At the same time, the equipment can also be remotely diagnosed and maintained to improve the reliability and operation efficiency of the equipment.
