Product Description Product DescriptionOur QY full hydraulic drilling jar, a sophisticated downhole tool designed to unleash unparalleled capability when a packer or guns become stubbornly stuck. This innovative tool delivers precise upward shocks, ingeniously pulling them loose without the need for tripping. Experience seamless, repeated jarring as the jar tool resets autonomously through the strategic application of string weight on the packer, ensuring efficient, hassle-free operations. Hydraulic drilling jars are precision-engineered, featuring two pistons ingeniously separated by a valve. As tension or compression is applied to the armed hydraulic jar, the fluid in one piston is expertly compressed, flowing to the other piston against significant flow resistance. This flow rate is precisely calibrated to control the arming time of the tool-striking a perfect balance where higher pulling or pushing forces result in more rapid arming. The moving distance, known as the stroke, reaches a critical position where compressed fluid is dramatically released through a bypass valve, propelling the fluid toward the second piston and equalizing pressure instantly. The greater the force applied, the higher the fluid's compression, leading to shorter arming times and more robust jarring force.In scenarios where the drill string becomes lodged at the bottom during drilling, or in the event of twist-offs, our jar delivers an effective upward release motion. For instances when the pipe is ensnared off-bottom in key seats, or for other reasons, the jar efficiently releases by jarring downwards. Utilizing upward reaming methods, the entire drill string can be successfully retrieved, enhancing operational reliability.When encountering differential sticking, the ability to seamlessly move the stuck pipe is essential to regaining rotation and circulation. Our jars allow for normal up and down movement, ensuring that jar actuation does not disrupt the directional orientation of the drillstring. This makes them invaluable neutral tools for downhole motor directional drilling and directional jetting, maintaining precision and control.Our jars serve as indispensable assets in a variety of complex operations, from fishing and cutting jobs to drilling, production tools, cementing, and coring operations. They prove their worth across multiple downhole applications, providing robust performance and reliability.The Full Hydraulic Drilling Jar Type QY is engineered with a state-of-the-art needle valve type structure, delivering both upward and downward hydraulic impact with stepless tonnage adjustment capabilities. This innovative design effectively safeguards the drill string and extends its service life. The hydraulic energy storage mechanism, featuring patented design, offers exceptional stability. With a delay time range of 30s to 240s and a working temperature range of -40oC to 180oC, it uses newly developed materials for superior performance and safety. This versatile tool is widely applicable in drilling, coring, workover, and fishing operations, setting new standards in the industry.Detailed Photos Product ParametersModelTool ODmm(in)ID of Boremm(in)ConnectionAPIAllowable Working TensilekN(Ib)Allowable Working TorquekN· m(lb· ft)Max.
