KINGWELL Other Types Drill 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.




Full-Hydraulic Drilling Jar Type KWⅡ
The up-down jarring of Full-Hydraulic Drilling Jar Type KWII 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 used for drilling, coring, work over and fishing etc.






Integral Mechanical Drilling Jar Type QW
Model “QW” Drilling Jar can be actuated by mechanical fully. The inner chamber cannot roduce high-pressure. The change of oiliness cannot impact jarring effect.The short overall length can reduce the harm of bending alternating stress, facilitating the conveyance. It has the low sealing property and reliable using property.It should be used for offshore drilling and directional Drilling.






Hydro-Mechanical Drilling Jar Type QWJX
Model QWJX 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. It can be used for directional hole, deep hole and so on.
