The bottom of Wireline Upstroke Jar usually is connected with the tool jarring upward. When the tool string is lowered to the predetermined location and is more than a little, stop lowering. Lift the tool string upward slightly at first, and after encountering an obstacle, control the lifting force above the basic definite value according to the adjusted jarring force in advance. Continue to lift the tool string upward in a constant speed until the steel wire loses tension suddenly, and then the jarring finished.
1. After several times of operations, disassemble the tool completely and clean it, inspect that whether the parts are damaged, and change the damaged parts in time.
2. Paint all threads with a layer of lubricating grease while assembling.
1. After several times of operations, inspect that whether the locking piece, spring and slip are damaged and change the damaged parts in time.
2. The Wireline Upstroke Jar is not suitable for the operations with large sand content in well to prevent the sand grain from entering into the jar to cause it to lose efficacy.
