DST tools 5" Hydraulic Jar


Type:Halliburton

Application:Drill stem testing

Working pressure:10000psi ~ 15000psi

Working condition:High pressure high temperature(HPHT)

Standard: API (American Petroleum Institute);

Service:H2S, CO2

Condition: New


Briefly Introduce   
The hydraulic jar is included as part of a toolstring to help remove stuck tools. The jar helps free a

stuck tool or toolstring by resisting a pull on the workstring. When the workstring is stretched by

the pull, tension in the jar is released and an upward impact is delivered to the stuck tool.

Features and Benefits

• Design of the hydraulic system ensures long life with little maintenance.

• Rig time is reduced.

• Jar can be recocked rapidly.

• Jar time delay is adjustable.

• Amount of pull to trip the jar can be varied within the limits of the time-delay system.

Operation

The temporary resistance that powers the jar is provided by a hydraulic time-delay system.Resistance is released when the metering sleeve inside the jar moves into a bypass section of the outer case. This action allows the special hydraulic oil to bypass rapidly.

The time delay required to release the temporary resistance varies in relation to the weight of the pull. For example, a light pull requires more time for release than a hard pull. When tools below the jar are stuck, a steady pull applied to the jar creates an upward impact blow to the string. The jar can be recocked when

the string is set down.

Specifications:
1. Halliburton type, all could change with Halliburton parts.
2. All equipments are produced according to API standard NACE MRO175-2002

Below are specfor you reference:

Add 10.00 in. (25.40 cm) for extended length for all jars except 3.00 in. For the 3.00 in. jar add

4.43 in. (11.25 cm).

²Maximum pull to trip is the pull placed on the jar to trip. Exceeding this pull might cause the

metering case to burst or the impact mandrel to part.

³Maximum pull is the pull that can be placed on the jar immediately after the jar trips, which may

be applied repeatedly without any damage. Any pull greater than this will fatigue the impact

mandrel if done repeatedly.

Meets NACE-0175 requirements (>175°F)

*Service temperature up to 450°F (dressed with 600 series o-rings and PEEK backup seals)

**The values of tensile, burst, and collapse strength are calculated with new tool conditions,

Lame's formulas with Von-Mise's Distortion Energy Theory for burst and collapse strength, and

stress area calculations for tensile strength.

***Pressure rating is defined as the differential pressure at the tool. (Differential pressure is the

difference in pressure between the casing annulus and the tool ID.)
