Wireline Tool String-Wireline Link Jar

Wireline Tool String-Link Jar

Product description:

Wireline Tubular jars/Wireline Link Jar are used in conjunction with running tools and other equipment to allow the operator to transmit effective jarring force up and down. The effect of jarring depends to a large extent on the weight of the jar upper link and the jar stroke, as well as tubing size and verticality, tool size and depth, fluid density and viscosity, well pressure, and wire size. Has a positive or negative effect on the shock's effect.Tubular Jar

Tubular jars/Link Jar are mostly used in oil pipes where cuttings or other possible foreign objects intrude. The jar is tubular in structure, with holes in the tube for fluid flow to allow easy movement of the plunger (jar rod).

Tubular jars/Link Jar are especially effective in large diameter tubing or casing, where chain jars will fail due to bending, while tubular jars are less prone to failure. some. Tubular jars with recommended displacement should be attached directly below the weighted rod.Wireline Link Jar

Advantage :

1) Before use, choose the appropriate type of jar according to the actual use environment and conditions, and do not use it blindly;

2) When using, carefully check whether the threaded connection of each component is in good condition and whether it is loose, so as to prevent some parts from falling off when going down the well and causing an accident;

3) After use, properly maintain the tool for the next use.
