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.

Supplier From Shenzhen, Guangdong, China
 
Fasteners are the general term of the class of mechanical parts used in fastening two or more parts (or components) into a whole. It is widely used in energy, electronics, electrical appliances, machinery, chemical, metallurgy, mold, hydraulic and other industries, at the same time, in various kinds of machinery, equipment, vehicles, ships, railway, bridge, construction, structure, tools, instruments, chemical, instruments and supplies, you can see all kinds of fasteners, is the most widely used mechanical foundation parts. It is characterized by a wide variety of variety specifications, different performance uses, and a very high degree of standardization, series, and generalization. Therefore, a class of fasteners that already have national standards is called standard fasteners, or simply standard ones.

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.
