Api 7K Double Acting Drilling Jar

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

Sl-swivel with spinner Xsl-swivel with spinner is a combination of swivel and kelly spinner, driven by air motor or hydraulic motor, with keyless connection adopted between spinner and central pipe of swivel.It is designed and manufactured according to api spec 8c "specification for drilling and production hoisting equipment" Skype: julia0402zcy Water swivel for drilling 1.Ma.Static load:4500kn 2.Max.Rotary speed:500r/min 3.Max.Wp:35mpa 4.Id of center pipe:75mm 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.
