Hydraulic bidirectional impact tool
As a standard tool for many downhole tubing strings, the coiled‑tubing jar can be used in conjunction with boosters or accelerators to perform various operations. In addition to applications such as jar‑induced release of stuck tools and fishing, it is also employed for tasks like opening and closing sliding sleeves, assisting drilling, crushing, shearing shear pins, and retrieving downhole components, thereby significantly enhancing the versatility of coiled‑tubing operations. The jar consists of an upper connector, an upper pressure body, a connecting body, a lower pressure body, a mandrel, a splined mandrel, a flushing tube, a locking ring, an upper piston, a lower piston, a flushing‑tube nut, and other components.

Product Features
- All-metal piston design, offering an exceptionally long service life;
- The high-strength steel body ensures tensile strength.
- With a compact design and greater impact force, it delivers more power than any other impact wrench of the same specification.
- The maximum operating temperature can reach 260 °C.
- Large diameter;
- The impact tool can operate bidirectionally under both compressive and tensile loads.
- It is equipped with an adjustment and compensation mechanism, eliminating the need to release hydraulic fluid based on downhole temperature prior to well entry.
