KINGWELL Drilling Jar Introduction:
 
The KINGWELL Drilling Jar is an effective tool for releasing stuck drill pipe and an accelerator is used to intensify force generated by the drilling jar at the upper depth of the well.
The KINGWELL Drilling Jar is designed to perform in any drilling environment, including offshore, onshore, conventional, horizontal and deep drilling.    
 
 


KINGWELL Other Types of Drilling Jar:

Mechanical Drilling Jar Type KW



The 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.

Mechanical & Hydraulic Drilling Jar Type KWQW



Model “KWQW” Drilling Jar belongs to the advanced product of model JYQ Jar. The up jarring can be acted by hydraulic as to realize the stepless tonnage control. The new hydraulic valve machine makes upjarring more stable and reliable. The down jarring can be acted mechanically. And the adjusting mechanism designed specially can realize manual regulation of down-jarring tonnage; the special slips construction makes down-jarring more stable and larger service. It can adopt the new special material for higher property and safety. It can be used for directional hole, deep hole and so on.
