QY type high temperature hydraulic drilling jar is a new generation of double-acting hydraulic jar that is fully upgraded by our company on the basis of the original QY full-hydraulic drilling jar. It has the characteristics of simple operation, adjustable shock tonnage, high temperature resistance, 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 at all temperatures not higher than 204ºC
Features
The superior machine structure is to further improve the machine maintainability.
The unique sealing structure is designed to improve the temperature resistance and improve the sealing reliability.
The core mechanism adopts the seal oil bath design to reduce the wear and tear of the moving parts and improve the life of the whole
The overflow area of the release channel is increased to reduce the running resistance and greatly improve the shock effect. The operating force of hydraulic releasing mechanism can be controlled on the ground by driller, and can be flexibly adjusted according to the downhole situation. The optional mechanical locking module is added to meet the needs of some special users. Increase the fast recovery function of the upward and downward strokes. The mandrel moves back to the middle position, and then the jar will do jarring again in either of the two directions

QYSZIII New Double Acting Hydraulic Drilling Jar is a new hydraulic drilling jar with locking mechanism developed on the basis of the structure of QYSZII double-acting hydraulic drilling jar. Besides the advantages of QYSZII type, it also has the following advantages.
1.The mechanical locking mechanism prevents unnecessary wear of the internal parts during the working process, and improves the working life. 2.The mechanical locking mechanism is functional safety and reliability, which is made by special process. The friction resistance is small, and the locking force is linear stability.
3.The locking mechanism can avoid the failure jarring caused by misoperation when connect simple root to the drill string or contact the hole bottom
