The up-down jarring of Full-Hydraulic Drilling Jar can be acted hydraulically, realizing the stepless control of up-down jarring tonnage. It can protect the drill string effectively and improve the using life. The hydraulic stored energy mechanism has the advantage of reliable property and good stability. The scope of time delay interval can be 30s～240s; the scope of service temperature can be -40℃～180℃. It can adopt the new special material for higher property and safety. It can normally be used for drilling, coring, work over and fishing etc.

Double Acting Hydraulic-Mechanical Drilling Jar can integrate the mechanical and hydraulic. The up jarring can be acted by hydraulic as to realize the stepless control of up jarring tonnage. The lock mechanism designed specially can avoid the mistaken jarring of up. The down jarring can be acted mechanically. It can adopt the new special material for higher property and safety and also can be used for directional hole, deep hole and so on.

Mechanical Drilling Jar up-down jarring tonnage can be adjusted for a large range.The Drilling Jar can be actuated by mechanical fully. The inner chamber cannot produce high-pressure. The change of oiliness cannot impact jarring effect.The low sealing property can make the using life improve observably.The mounted special flexible joint can reduce the bending stress of Jar body effectively.It should adopt the new special material as to insure the higher performance.It should be used for straight hole, deep hole, complicated hole and directional hole.

Super Jar is a hydraulic tool, realizing the stepless control of up jarring tonnage. The scope of time delay interval can be 30s～240s; the scope of service temperature can be -40℃～180℃. It can be used with Accelerator as to obtain the remarkable jarring effect. And it can supply the new special material as the requirement as to obtain higher using property and safety. It should be used for fishing and coring of up jarring.
