Product Description Product DescriptionIntroducing our sophisticated hydraulic drilling jar, a revolutionary downhole tool engineered to seamlessly handle challenging scenarios such as packer or gun entrapment. This indispensable tool provides powerful upward shocks to liberate stuck equipment effortlessly, eliminating the need for tripping. The advanced jar tool ensures continuous jarring action by automatically resetting with the strategic application of string weight on the packer, making it an essential asset in your drilling operations. Hydraulic drilling jars are expertly crafted with a dual-piston system, partitioned by a precision valve. Upon exerting tension or compression on the armed hydraulic jar, the fluid within one piston undergoes compression and transitions to the opposing piston, overcoming high flow resistance. The control over flow rate determines the arming duration-greater pulling or pushing forces culminate in expedited arming. This progression, known as the stroke, peaks when the compressed fluid is abruptly released through a bypass valve, propelling the fluid toward the second piston and instantaneously balancing the pressure between the pistons. Enhanced force application results in heightened fluid compression, diminished arming duration, and amplified jarring impact.In scenarios where the drill string becomes immobile at the bottom during drilling or experiences twist-offs, the jar delivers a potent upwards release. Conversely, if the pipe becomes immobilized off-bottom within key seats or other impediments, downward jarring effectively resolves the issue. Subsequently, upward reaming techniques facilitate the recovery of the entire drill string, demonstrating the jar's invaluable contribution to successful drilling operations.Upon encountering differential sticking, mobilizing the immobilized pipe is crucial to reinstating rotation and circulation. In such instances, jars exhibit their versatility, moving seamlessly up and down without disrupting the directional orientation of the drillstring. This makes them ideal neutral tools for downhole motor directional drilling and precise directional jetting, ensuring smooth and efficient operations.Our hydraulic jars are indispensable across an array of applications, excelling in fishing and cutting tasks as well as in drilling and production tools. They are integral to cementing, coring operations, and myriad downhole endeavors, providing unmatched utility and adaptability to meet diverse operational needs.The Full Hydraulic Drilling Jar Type QY is distinguished by its innovative needle valve type structure, enabling both upward and downward hydraulic impacts with seamless tonnage adjustments. This design not only safeguards the drill string but also extends its longevity. The hydraulic energy storage mechanism, secured by patented design, ensures exceptional stability. With a delay time range of 30s to 240s and a robust working temperature span of -40oC to 180oC, this jar employs cutting-edge materials for superior performance and safety. Its versatility is unmatched, making it a preferred choice for drilling, coring, workover, and fishing operations.Detailed Photos Product ParametersModelTool ODmm(in)ID of Boremm(in)ConnectionAPIAllowable Working TensilekN(Ib)Allowable Working TorquekN· m(lb· ft)Max.
