What is the purpose of the drilling jar?
The drilling jar is used to free stuck drill strings in drilling operations by applying a controlled impact force.
Can the jarring force be adjusted?
Yes, the hydraulic section allows for adjusting the jarring force, while the mechanical section maintains consistent performance.
What material is the drilling jar made of?
The QYSZ Type Drilling Jar is made from high-quality carbon steel, forged for enhanced strength and durability.
How is the product shipped?
The product is shipped in standard export packaging, with options for customized packaging based on the client's needs.
Can I customize the product?

API spec 7-1 QJZ Type Full Mechanical Drilling Jar
Description
The drilling jar which is connected with drill tool and worked with drill string is a downhole stuck freeing tool in drilling operation. It is a first selected tool for directional well, complicated well and deep well. The drilling jar is consisting of ZSJ type drilling up jar and ZXJ type drilling down jar, they can both be used mutually or operated separately. The up jarring section makes use of hydraulic mechanism, the jarring force can be adjusted according to up elevating load but can not exceed the max, load for tool load rated. The down jarring section takes use of mechanical friction mechanism, the jarring force is well readjusted by adjusting device before put into downhole. No re-adjustment can be allowed after jar is put into downhole.
