API SPEC 11B Straight Bar for Coiled Tubing BHA Straight Bar is a kind of product with large wall thickness similar to tubing pup joint. It is generally utilised together with accelerator and jar
Straight Bar is a kind of product with large wall thickness similar to tubing pup joint. It is generally utilised together with accelerator and jar to form a jar assembly. The ordinary Straight Bar is made of solid round steel and most commonly used. In addition, there are Tungsten Alloy Straight Bars and Lead Straight Bars. Compared with the ordinary, these two can provide greater tool load and increase the efficiency of jarring.
Applications:
1. At the lowest part of the sucker rod to generate continuous tension;
2. Effectively eliminate the pressure of the sucker rod and reduce the amount of fatigue damage;
3. Reduce the wear of sucker rod and tubing;
4. Increase the weight of the coiled tubing downhole tool string, increase the extension of the tool, and ensure sufficient impact force during the jarring operation to successfully complete the operation;
5. Used as a coiled tubing tool for loading, retrieving and aggravating during fishing operations.
