The wireline spring jar consists of fishing neck, sleeve, jar stem, pup joint, locking piece, slip, spring, etc.When the jar is closed, the slip on the jar stem will stretch and clamp on the extension rod under the function of spring. When lifting, the jar stem will drive the slip to pull the extension rod and squeeze the disc spring to reserve energy. When the jar stem runs for some stroke, the slip will be squeezed by the pup joint and disconnect with the extension rod. Then theenergy of disc spring will release immediately to finish the jarring effect.
1. After several times of use, check whether the lock block, spring and slip are damaged and replace them in time;
2.The wireline spring jar only has the upward jar function for many times, and cannot be used for downward jar.
3.wireline spring jar is not suitable for operation in wells with large sand content, so as to avoid sand debris entering the jar and causing jar failure.
