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.
Main feature:
Drilling jar with national oilwell varco
Hydromechanical drilling jar halliborton
Operating manual double acting drilling jar
Used in geothermal drilling and wells

Water swivel for drilling
The swivel includes two main categories, which are common swivel and double duty swivel. Double duty swivel is a common swivel combined with a spinner. Common swivel consists of swivel bail, shell, support, gooseneck, central pipe, master bearing, joint and other parts. The lower end is connected with kelly stem by reg thread. The swivel bail is hung on the hook. Gooseneck and rotary hose can be connected by reg thread connection or union connection.
Washpipe packing set assembly adopts cassette structure, so it can be quickly replaced without disassembling rotary hose and gooseneck. 3lp and 4lp internal or external thread hose connection thread are available for you. We can also manufacture low temperature resistant swivel according to customer's requirements.
Our swivel meets api spec 8cpsl1 standards. It has been awarded the api certification issued by the american petroleum institute and is allowed to use api monogram.

The Safety Clamp is one of the most valuable tools for well drilling. It helps guard against dropping flush-joint pipe, streamlined drill collars, etc. into the hole while making-up or breaking-out the string. It is necessary tools for drill rig while drilling operation is ongoing.

The Safety Clamp can be deviled into MP, the WA-T and WA-C type.
MP-S /MP-R /MP-M /MP-L /MP-XL

Application: Used as Flexible connection between standpipe and swivel (Rotary Drilling) or between pump and standpipe (Rotary Vibrator) for pumping mud at extra high pressures in oil drilling and natural gas exploration work (including 50D, 70D).

Temperature Range: -30�°C~ 120�°C, or manufactured upon customers' requirements

Hose Reinforcement:2~ 6 layers spiraled by single high-strength steel wire, and rubber as a binder to make the layers into one complete and sound construction

Lining: Principally NBR constructed, featuring oil-resistant, abrasion-resistant, acid, alkali & flame resistant.

Hose Cover: Primarily CR fabricated, featuring oil-resistant, abrasion-resistant, weatherproof and anti-ageing

Coupling Type: NKT 60X2.5 , HAMMER UNION 1502 , BSPT 4"

Reference Standard: API Spec 7K,ISO 6807

drill hose : it is composed of an inner rubber layer protection layer, middle rubber layer, steel wire spiral layer and external rubber cover
Use: The steel wire spiral drilling rubber hose are used in oil field well cementing. well pulling , petroleum geology exploration, small drilling machine, water conveyance, coal excavation. Used to carry slurry, normal temperature water, and other fluids.

1. Drilling jar is connected with drill tool and worked with drill string is a downhole stuck freeing tool in drilling operation .It is a first selected tool for directional well,complicated well and deep well.

2. The drilling jar is consisting of ZSJ type drilling up jar and ZXJ type drilling down jar,both they can be used mutually or operated separately .

3. The up jarring section takes use of hydraulic mechanism,the jarring force can be adjusted according to up elevating load but can not exceed the max.load for tool load rated .

4.The down jarring section takes use of mechanical friction mechanism, the jarring force is well preadjusted by adjusting device before put into downhole.No re-adjustment can be allowed after jar is put into downhole.
