Hydraulic jar tester is an necessary tool to test tensile strength and pressure performance of jars, shock absorber, jar intensifiers. It also can test the strength of thread connection. The hydraulic jar tester is designed and manufactured by integrating the advanced technology from same equipment abroad and the actual situation of the petroleum industry in china. Advantages such as easy and steady operation, big push/pull tonnages, high safety feature.
Spiral drill collar is used to reduce contact area with hole so as to avoid efficiently bit sticking from differential pressure. MS brand spiral drill collars are manufactured strictly according to API Spec7-1 and standard SY5144.
Drill collar is mainly used to provide bit weight to drill bit so that drill pipe is in tension. Especially drill collar can keep drill bit centralized and hole track by large rigidity. MS brand drill collar are manufactured strictly from API Spec7-1 and SY5411 standard.
The wall thickness of heavy weight drill pipe is between drill pipe and drill collar. Its structure is similar with drill pipe. It is made from premium alloyed steel. Its both tool joints and middle upset are welded hardbands. Technical parameters meet with API Spec7-1 standard.
Xj650 workover rig, with 1470kn of max. Static hook load, is the largest self-propelled workover equipment with single engine, mainly used for medium & deep well workover , oil testing, fishing and pump check operations. It is equipped with a lifting system and a rotary operating system. It is widely applied in many fields. It can be used for lateral drilling and shallow well drilling operation if equipped with a rotary table and relevant parts. Reasonable layout, compact structure, easy transportation, convenient operation and maintenance.
