A wireline accelerator is wireline stretch simulator device used in conjunction with hydraulic or spring jars when jarring at shallow depths in the wellbore.
he wirline accelerator is available in sizes from 1-1/2＂to 3.00＂OD and standard or H2S trim.
Upward tension on the wireline compresses the spring with the accelerator assembly and the stored energy is transferred to the hydraulic or spring jars located further down the tool string.
A combination of surface wireline tension and the energy stored within the spring of the accelerator will eventually cause the hydraulic or spring jar to fire, thus releasing totally the energy stored within the spring. The tension of the wireline can then be relaxed and the operation repeated until the subsurface tool is jarred free.
Size | Fishing neck | Connection |
1.5＂ | 1.375＂ | 15/16UN |
1.75＂ | 1.375＂ | 15/16UN |
1.875＂ | 1.75＂ | 1-1/16UN |
2.125＂ | 1.75＂ | 1-1/16UN |
2.5＂ | 2.313＂ | 1-9/16UN |
3＂ | 2.313＂ | 1-9/16UN |
Note. More customized parts are available upon request.
The wireline accelerator consists of top sub, sleeve, spring, mandrel, caps, lower subs, etc..Spring is the major part. The top of the accelerator connects with stems and the bottom connects with the hydraulic or spring jar.
