The Fishing Bumper Sub is Downward Impact Specialist. The Fishing Bumper Sub is Dual-Energy Storage System. The Fishing Bumper Sub is Rugged Mechanical Simplicity. The Fishing Bumper Sub is Adjustable Impact Dynamics. The Fishing Bumper Sub is Multi-Functional Integration.
The ZJS type jar intensifier is a kind of down hole fishing jar designed to increase jarring energy to top jar.Therefore,it must be run in conjunction with YSJ type hydraulic top jar or CSJ type super jar.Its main function is to supply acceleration to the upper end of the jar during the free jarring stroke.With a special function,the intensifier is essentially a fluid spring which not only can accelerate the top jarring action but also make the jarring action directly to strike on the fish and reduce damages to the drill tool and fishing tool.
The two ways shock absorbers are used to simultaneously slow down or eliminate thevertical or horizontal shock from drill string. It can reduce the damage due to shocking to drill bit,drilling tool and surface drilling tool so as to enhance drilling speed and reduce drilling cost.
The one-way shock absorber (bumper )is a kind of drilling tool.It can effect shock absorbing and shock reduction by means of elasticdeforming andanti-coagulationproduced from hydraulic oil under the outside force. Its advantages such as simple structure, reliable workingperformance and easy to maintain can well absorb shocking andvibrating load from drill strings during drilling operation. Therefore, using of shock absorber can raise in structure the service life of drill bit anddrill pipe, speed up drilling, get rid of drilling jumping, well protectsurface equipments and drilling tools.
Double-Acting Hydraulic Mechanical Drilling Jar provide Dual-Action Efficiency. Double-Acting Hydraulic Mechanical Drilling Jar provide Hydraulic-Mechanical Synergy. Double-Acting Hydraulic Mechanical Drilling Jar, forged alloy steel body with anti-wear coatings ensures longevity in harsh downhole environments.
Hydraulic up jar is usedtobe freefromdrillingsticking, throughhydraulicprinciple,by means of elastic potential produced from drill tool elastic deformation.Once the elasticpotential energy is released, it would produce a large up striking load to reach apurpose of fishing and coring.Itfeatureseasystructures,strongjarringforce,easytoreturn,convenientoperation.Ifitis usedwithZJStypejarintensifier,itmaygainbetterjarringeffect.
Super Fishing Jar, industry-Leading Jarring Force Super Fishing Jar,Torque & Circulation Optimized Super Fishing Jar, easily adjustable settings and intuitive operation for oil tools teams in drilling/geological exploration.
XINRUIDE Arrow Type Back Pressure valve is an important tool preventing of blowout. The design of the Arrow Type Back Pressure valve allows for an on-site determination of back pressure to be set at surface.
A lift Sub enables safe and efficient handling of straight OD tubulars such as drill collars,shock tools,jars,directional equipment and other tools by using the drill pipe elevators.
The internal hook is a fishing tool generally used inside casings and oil tubings for fishing ropes and other fishes such as wire-lines,cables,logging wire-lines and paraffin cutters.
The External Hook is used inside casings and tubings to catch all kinds of ropes,lifting bails,hollow short cylinders,short rope slings such as wire-lines,logging steel pieces,cables,etc.
Releasable Reversing Overshot,a new type of fishing tool,has many advantages owned by various overshot,box tap and the like.Its distinguishing features are as follows: to unscrew and recover the stuck fish;To release the fish down hole if necessary;to crculate the washing fluid as one of the accessories for reversing tools.It is widely used in well servicing.
