Product Description Product DescriptionJYSZ Double Action Hydraulic-Mechanical Drilling Jar(The drilling jar is a double acting jar) This drilling jar is designed to deliver hydraulic delay when jarring in the up direction, and mechanical release when jarring in the down direction. It provides excellent functional stability and strong jarring forces in both jarring direction. It is used to free stuck drill string components and is recommended for directional/deep wells drilling application. Working principleUp JarringLower the drill stem to ensure that drilling jar is closed completely (in locking position). Up jarring is achieved by slowly increasing the lifting force on the drill stem, until there is sufficient pull force to overcome the spring resistance and initial hydraulic time delay. During the time delay, the overpull at surface can be adjusted to vary the desired impact force. When the mandrel reaches the trigger position, there is a sudden release in resistance, the elastic potential energy stored within the drill string will be transmitted to forward up jarring impact energy. After impact, apply a downward force sufficient to close jar in locking position, then repeat the jarring cycle as required. Down JarringLift and lower the drill stem to ensure that the drilling jar is closed completely (in locking position). Down Jarring is achieved by applying sufficient downward force to compress the spring and store elastic potential energy. When the pressure of the jar is greater than the desired unlocking force, the grapple will slide away from the mandrel to release the locking, performing down jarring action. Repeat the procedures to produce continuous down jarring action.Product ParametersSpecification-Double Action Hydraulic-Mechanical Drilling JarModelQYSZ121BQYSZ159CQYSZ165BQYSZ172CQYSZ178BQYSZ203BQYSZ241Product Code1808000181000018110001812000181300018150001817000O.D.
