Description about well logging machine
 GDJ series winch is a special equipment for geophysical exploration and geological survey. It is mainly used with GDQ-2D integrated digital logging equipment and can also be used with other logging equipment. Most GDJ series winches are anti-magnetic design, stepless speed adjustment and automatic cable arrangement. The performance can be applied to various geological prospecting areas. DJ series winch equipment adopts frequency conversion motor, dc motor, ac asynchronous motor as power source, and has a wide range of speed regulation, smooth variable speed, convenient operation, simple maintenance and so on. It can be used in geophysical prospecting and geological survey work on the land, sea, plateau (which is less than 5,500 meters above sea level) and other environments on the earth.

FAQ

What happens if the power fails while the probe is deep in the borehole?

Answer: Professional electric logging winches are equipped with a mechanical emergency brake or a self-locking gearbox. If power drops, the brake automatically engages to prevent the probe from free-falling to the bottom of the well, which could destroy the equipment.

What are the risks of a poor level-wind system?
Answer: An automatic level-wind ensures the cable spools evenly across the drum. Without it, the cable can bunch up, overlap, and crush itself under tension. This causes "bird-nesting" or kinking, which permanently ruins expensive armored wireline and causes depth tracking errors.

How often should the cablehead be checked or remade ("reheaded")?

Answer: The cablehead connector bears the absolute brunt of downhole tension and fluid pressure.Before every run: Operators must use a high-range multimeter to verify electrical isolation across the cablehead pin connector. A reading less than 20 signifies fluid ingress or insulation failure.  Periodic Reheading: The mechanical termination must be routinely chopped and re-terminated by a trained field technician after exposure to highly corrosive fluid environments, high temperatures, or if any structural wire fatigue is noted near the tool joint.
