In the drilling operation, the underground drill string (BHA) often causes a drill sticking accident due to the complex geological structure, improper technical measures and mud, pipe string, wellbore and other reasons. The drill sticking has a great influence on the drilling work, and the damage is also deep. If it is not handled properly, it will not only consume a long time, it will lose the drilling footage, but also may cause the accident to deteriorate and even cause the oil and gas wells to be scrapped. The jar is an effective tool for lifting the sticking. Therefore, in the drilling speed and drilling benefits more and more attention today, the correct choice and use of jar products will bring considerable economic benefits for the drilling industry.

The effect and use of the jar is related to the design and manufacture of the product and is closely related to the reasonable use of the customer. In order to ensure your correct operation, please read this manual carefully before using the product. The reliability and performance parameters of our products after they have been used and repaired may vary depending on whether the quality of the product is properly and reasonably used and maintained.

ZH Full Hydraulic Drilling Jar is a kind of Drilling Jar with locking mechanism, which combines the jarring up and down actions. This series of jar is suitable for various drilling operations. When used, it goes downhole with BHA. For some reason blocked or stuck occurs in the downhole in the process of drilling, the operator can lift or lower the drilling string on the drilling platform to make the drilling jar provide a huge impact and strike upward or downward to free the jar so that the drilling operation could be resumed quickly.

ZH Full Hydraulic Drilling Jar gives full consideration to a series of serious impact on problems of drilling such as high temperature, high pressure, high torque, and so on. A series of specific design has been adopted to make the Full Hydraulic Drilling Jar has the advantages of simple operation, big shock force, convenient adjustment, high connection strength, stable performance, safety and reliability, convenient maintenance and so on many merits. Done properly, mistaken shock will not occur when the product in the drilling, tripping, making a connection or hit the downhole. The hydraulic delay function allows the operator to dynamically adjust jarring up and down forces. Fully sealed oil bath lubrication is helpful to reduce wear and tear, thus improve the service life. In addition, the position of the jar is relatively free in the BHA, and it can be placed in various positions such as tension, neutral point, compression and so on, so that it can meet the needs of drilling operation under various conditions, such as land and ocean.

Full Hydraulic Drilling Jar consists of connecting mechanism, sealing mechanism, jarring mechanism, hydraulic damping mechanism, energy storage mechanism, and locking mechanism, etc.
