Wireline Multi -Parameter Geophysical Well Logging For Water Well Survey
How to use geophysical well logging tool?
1. The instrument should be placed in the open space in the field. The space should be flat and dry land. It is about 10 meters from the winch to the well.
2. The pulley should be firmly fixed on the frame before setting on the well, so as not to loose the frame into the well. Then, connect 4 lines on the logger box, which is the power cord, USB line, depth encoder line, and collector ring line.
3. Note: geophysical well logging tool use 220V power supply, please use Multimeter to measure and check before connecting, so as not to be mistaken for burning the instrument.

How to use geophysical well logging winch?
1. Check if there are any loosing and damaged parts before use
2. Check whether the wires are reliable.
3. Make sure that electric motor is good to ground.
4. Please note that the measuring cable is a 1-core wire cable with a force of 300kg and a resistance of less than 20 ohms per 100 meters.
4. Cable winch can be electric or manual. In the case of an unexpected power failure in the work, the instrument will be upgraded by hand, and the active gear and the reducer should be removed by the left arm.
