YJ Type Hydraulic Shock Absorber

Shock absorbers

Hydraulic Shock Absorber Type YJ should be connected with the drilling string close to the bit. It can absorb or reduce axial vibration and thrust load of the drilling string, and have a good result for prolonging the service life of the bit and protecting the drilling tools as well as the surface equipment.

SJ Type Shock Absorber
Shock Absorber Type SJ should be connected with the drilling string close to the bit. It can reduce or absorb both longitudinal and circumferential vibration of the drilling string in drilling operations. It can achieve the optimum combination of drill pressure and drill speed, reduce the drilling cost and promote the drilling efficiency.

Reverse circulation fishing magnets

CLF type fishing magnet in petroleum and geology exploration is used for fishing of small fallen objects in the down hole.With some of advantages such as simply structure, easy to operate, reliable performance, small size and lightweight,it is equipped with permanent magnet iron which can attract small objects such as teeth wheel, palm, tong teeth and tool so that small objects in down hole are fished and the well bottom is cleaned up.

In drilling and work over opertion,the releasing spear is a tool mainly used for fishing of drill pipe,oil pipe and casing from fish hole.It can be used with internal cutter ,bumper jar etc.

The LL-F type reverse circulation junk basket is used to retrieve all types of small junk objects such as cone,cutter,hand tool and junks from the bottom hole.During drilling operation,it produces a local reverse circulation of fluid at well core so as to effect a complete recovery of junk in the junk basket .Especially when PDC bit is used ,cleaning bottom well by the tool becmes very necessary to ensure the bit with a normal application.The reverse circulation junk basket therefore becomes an essential tool in oil ,geology exploration and drilling engineering.

Reversing subs

Reversing sub is also called reversing spear which is a special tool for reversing stuck drill stem above stuck point in drilling and work over operation. When make fishing or reversing, if fallen object is stuck or fail to be released, the tool can released from thread connection of reversing sub to take out fishing tool.

Mechanical internal cutters

The mechanical internal cutter is a special tool to cut pipe in pipe string. With exception of coupling, it can cut at any position of fish. During cutting operation,the releasing spear can be connected above internal cutter, after finish cutting,pipe string above cutting position can be lifted out at a time.
