Geophysical Borehole Logging Equipment with The Lightest Electric Logging Winch for Sale

Beneath the Earth's surface lies a hidden world rich with vital information crucial for understanding geological formations, hydrocarbon reserves, and environmental conditions. At the heart of unraveling these mysteries lies the well logging tool, a remarkable instrument designed to probe deep into the Earth's layers and unveil its secrets.

Imagine a sleek, slender device delicately lowered into a borehole, equipped with an array of sensors and detectors capable of capturing a wealth of data as it traverses the depths below. This is the well logging tool—an indispensable companion in the exploration and exploitation of oil and gas reservoirs, as well as in the assessment of groundwater resources and geological hazards.

With unparalleled precision, the well logging tool measures various properties of the subsurface formations it encounters. From electrical resistivity and natural gamma radiation to acoustic velocity and neutron porosity, it provides a comprehensive portrait of the underground environment. Each data point serves as a piece in the intricate puzzle of subsurface characterization, aiding geoscientists and engineers in making informed decisions crucial for resource evaluation and reservoir management.

  The function of the ground integrated host of the GDQ-2D system is to supply a standard power supply (+200V) to the downhole probe and to communicate with the downhole probe in two directions. The communication signal is a digital signal that is coded and can perform forward error correction. The working state and opening of the downhole probe are controlled by downward instructions. The parameters measured by the downhole probe are transmitted to the integrated host, and after demodulation and processing, they are sent to the PC for further data processing and saving the result data. The communication interface between the integrated host and the PC is USB1.0 or USB2.0, and the user can also choose RS232 mode. The integrated host works in a multi-tasking mode, and multiple MCUs are integrated to complete fault self-detection, power supply protection, modulation and demodulation, and depth measurement, ensuring smooth oversampling and very strong real-time performance.

   Each single-parameter or combined-parameter probe is composed of a standard power supply module, a modulation and demodulation module, and its own measurement and processing module. Except for the different measurement and processing modules, the external interfaces of the probes are completely consistent. In actual work, users do not need to adjust factors such as power supply current, signal amplification, etc. There is no adjustment device on the ground. Changing a probe is as convenient as changing an incandescent bulb. Most probes have two specifications of Φ40mm or Φ50mm to adapt to different borehole diameter applications. At present, there are more than 20 parameters that can be measured by the probe, including electricity, magnetism, density, radioactivity, borehole spatial orientation, temperature, pressure, flow, sound velocity, etc. Whether it is metal mines, coal fields, oil fields, radioactive mines, salt wells, or hydrological wells, they are all covered. The parameters of commonly used probes are also consistent with international practices.

   The software of GDQ-2D system is a visualization software running under Windows—XP or NT. The software consists of modules such as acquisition processing, scale calibration, curve editing, analysis filtering, etc. The function is very powerful, and the required PC configuration is not very high. The result data can be stored in the database for management or saved as a single data file for management. It can be exported to a format readable by software such as Sufer. The graphic results can be drawn by various printers, thermal plotters and other devices.

   The winch equipped with GDQ-2D is currently the lightest electric logging winch. The winch is made of high-strength aluminum alloy. It has significant features such as non-magnetic, low sensitivity, light weight and durability. The winch works with stepless speed change and has a very reliable anti-slip function, manual function, and fully automatic tight cable arrangement function. Logging cables can range from armored single core to rubber multi-core according to the equipment required by the user. Everything from coaxial to multi-core spirals can be used. JHQ-2D downhole instrument does not have strict requirements on cables

This set of equipment has the following advantages over other similar products:

(1) the measurement parameters are large and the scope is wide.

(2) the reliability is high and the Mean Time Between Failure (MTBF) is long.

(3) portable, convenient for mobile transportation.

(4) operating and maintenance is simple.

The main reason for these advantages is that the design and development is absorbing other's merits, fully considering the variouts needs of the industry, and considering the competitiveness in the international market. GDQ - 2D 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.
