Submersible pump wells downhole operation of the cable protection
When you go submersible pump will be neglected, so Sky Wave Pump for you to summarize the details of the place
a. Most of the damage to the cable is due to improper handling or downhole operation, so downhole operation is very important
b. Starting the tubing, it is extremely important to start and stop slowly and steadily. Severe acceleration or deceleration is the main reason for cable damage. From the tubing speed shall not exceed 0.7m / s.
c. The pulling force of the cables between the cable drum and the guide wheel during the downhole operation should be minimized.
d. The cable clamps and cable protectors must go through the cables until the cable armors are slightly deformed but not crushed during the well-digging process. Generally, two clamps should be put on each tubing, and one card should be stuck above the tubing coupling 0.5m-1m Department, a card in the middle of the tubing
note:
1. Do not install the cable clamp at the cable connection. Generally, install a cable clamp at the upper and lower parts to bear the load.
2. At the bottom of the 1-2 tubing, consider the appropriate use of several cable clamps (5 or more), because the salvage operation here may cut off the tubing.
e. Downhole operation, generally every 50 under the tube to measure the submersible pump insulation resistance, DC resistance once down to the bottom of a careful measurement of insulation resistance and DC resistance and make a record.
f. It is vital that the cable be allowed to relax in the well and that the tubing must not be rotated at all times, and that the cable must be parallel to the tubing and must not be caught on the tubing. Care must be taken in handling
If the submersible pump unit is lowered into a deviated well, a cable protector is required for each cable tie to protect the cable. Place the cable in the cable protector slot and secure the cable protector to the tubing collar with a screw. Do not move and rotate
