Product Description
QY type high temperature hydraulic drilling jar is a new generation dual-acting hydraulic jar which is fully upgraded by our company on the basis of the original QYSZ II full-hydraulic drilling jar. It has the characteristics of simple operation, adjustable shock tonnage, etc. This type of drilling jar adopts a new hydraulic delay release system, which has excellent reliability and wide adaptability.
Application
It is suitable for all conventional wells,inclined wells and large displacement wells whose temperature is not higher than 160ºC.
Product Features
Optimized machine structure improves the maintainability of the machine.
The selected sealing material improves the sealing reliability.
Oil bath sealing design is adopted to the core mechanism to reduce the wear of moving parts improving the working life of whole machine.
Enlarged overflow area of the release channel reduces the running resistance improving the jarring effect obviously.
The operating force of hydraulic releasing mechanism can be controlled on the ground. Driller can adjust the operating force flexibly according to the downhole condition.
The optional mechanical locking module is available to meet the special needs of some special customers.
Upper and lower stroke quick recovery function is optional. The mandrel moves back to the middle position and is ready to jar again to any direction.
