Hydraulic Jar Suppliers and Manufacturers

Hydraulic jar (up / down) designed to use accelerator and flow sub form a coiled tubing short heavy string. The Jar delay device let the energy stored in the stretched and elongated string accelerator, when the energy released will have a great impact, generating shock effect, loose card tool stuck. Up jarring Lowering drill string to make drilling jar closed completely (in locking position), elevating drill string by the order of small tonnage to larger tonnage, which make spring and hydraulic cylinder delay, when mandrel move to a position and become release resistance, the spring force stored in drill string will transfer to upforward energy and up jarring. Repeating the above several times can force tool to produce continues up jarring. Down jarring Move up and down the drill string to make drilling jar closed completely (in locking position), lowering drill string to make spring compressed and stored energy. When pressure of jar is larger than the desired lower unlocking force, grapple will slide out from mandrel to release the locking and make down jarring. Repeating the above several times can force tool to produce continues down jarring.

Description YJS Hydraulic Jar Intensifie YJS hydraulic jar intensifier is a kind of down hole fishing jar tool designed to increase jarring function for up jar. So it must be used together with super fishing jar. It could accelerate for the top end of jar and the drill collar connecting with its bottom end when working, so to get larger jarring force on stuck point, and reduce quake of drill stem springback after jarring at the same time. We produce H2S resistance Jars, which adopt high quality import sulfur-resistance material.

Quick information Brand name: jingmeiplace of origin: china Description Mechanical-hydraulic drilling jar Sjy double-acting / mechanical-hydraulic drilling jar Sjy double-acting mechanical-hydraulic drilling jar integrates upward jarring with downward jarring hydraulic drilling jar with mechanical interlocking. It can suit for all kinds of drilling operations, and landing into the well with drilling tools assembly when used. When the drilling tools are stuck, it can make drilling jar generate upward or downward jarring force through lifting and landing the drill strings, so it can release resistance and the stick by many time jarring, and recover normal drilling operation promptly. If adjust the release force, it can be adjusted any time on the spot. We produce h2s resistance jars, which adopt high quality import sul fur-resistance material. Modelod Mm(in)id Mm(in)conn. Apimax.

Hydraulic jar is one of the drilling jars types used in drilling operations to free stuck pipe problem. Orchid Energy hydraulic drilling jar will allow the operator to apply variable impact in both the up and down directions. It can protect the drill string effectively and improve the using life. The hydraulic stored energy mechanism has the advantage of reliable property and good stability. The scope of time delay interval can be 30s 240s; the scope of service temperature can be -40 180. It can adopt the new special material for higher property and safety. It can normally used for drilling, coring, work over and fishing etc.

Hydraulic Mechanical Drilling Jar is integrate hydraulic principle with mechanical principle and applies to all kinds of drilling operations and be used through combining with drilling tools. This jar is equipped with a mechanical safety latch and mechanical latch for jarring downwards. When the downhole tools get struck, the hydraulic mechanical drilling jar can generate upward jarring or downward jarring through lifting and landing drilling strings, and release block and stuck by several times jarring to recover normal drilling operation promptly. Avoiding resistance and stuck which may cause further accident and caused greater economic loss. If releasing force is failed, it can dynamically adjust at any time on sites.

1.Description: The mechanical-hydraulic drilling jar is a jarring and stuck releasing tool. It integrates the up jar and down jar and can release the stuck accident occurring during drilling operation. The drilling jar is an ideal tool for directional well and deep well drilling. Operating principle 1.Operating principle of up jar Lifting drilling tool, slip assembly which bear the acting of dish reed elastic force and slip locking force compels latch mechanism of slip clasp slip mandrel. While slip mandrel up run with mandrel to overcome slip locking force and damping action between hydraulic valve assembly and spindle extension, jar Make drill stem accumulate energy, delay time. When mandrel up run to the state of release constraint, elastic potential energy accumulated in drill stem will convert to upward kinetic energy, generate up jar. If need sequence up jar, you need fed off drilling tool till relock latch mechanism, reduplication above process, Generate sequence up jar. 2.Operating principle of down jar The loosen load of down jar lock can be transfer as per in demand .There are a certain ratio between up locking force and down locking force , and the ratio is adjustable. If down jar, fed off drilling tool until pressure reach to down locking force, jar should generate down jar force. If need to repeat jar, lifting drilling tool to anew securing position repeat above process.
