Releasing and Circulating OvershotLT Overshot is one of the fishing tools which is fishing the pipes
externally. It can catch drill collar, drill pipe, tubing, subs and other pipes.Because of the seals, the fluid can circulate with the high pump pressure after catching the fish. The top of the fish will be milled by under mill shoe. It can aslo work with jars to catch the stuck fishes. If the catched fish can’t be release from stucking ,we could release the oveshot and lifting the drill string.
Short Catch Overshot Short catch overshot is used for catching short length fish which the stuck point is closed or
above the coupling, such as tubing, drill pipe, sucker rod and subs. If the fish head is more than 50 mm, it will be catched. The short catch overshot has features of small volume, low cost, reasonable structure design, convenient to use and wide application. It can prevent overshot self-locked when in large torque, and improve the fishing success rate and work efficiency.

It has well structure and well property. Because of the different connecting components, there are different requirments to crossover subs. It has “A”, “B” and “C” type.
Specification:All sizes.

Wear SubIn rotating drilling process, the rotating power of drill bit is from rotary rig platform or top-drive equipment
through the drill stem. In the process of directional,dirlling because of the friction between drill stem and well wall or drill stem and casing, it is difficult to transfer the rotating power, especially in horizontal well. Because of the loss of torque, it will effect the rig efficiency and reduce the rig drilling power. The friction between drill stem and well wall or drill stem and casing will reduce the life of drill stem and casing, also the well wall will become irregularity. Because of the loss of passing torque, it should increase the torque load of drill stem in order to keep the drilling torque on bit. So it will reduce the drill stem’s safety factor. All these will effect the safety, quality and rapid drilling.
Wear sub can valid resolve the above mentioned problems in the process of oil and gas drilling. It can reduce the drilling torque and friction between drill stem and casing by rotating drilling. So it can protect the casing and drill pipe.

Oriented SubThe oriented sub is used for the bent screw drilling tool getting into orientated. Put the gradiograph in the
directional bond. It is used for kicking off in directional well, side tracking and vertical well. It has the advantages of simple structure, easy to use and low cost.
Oriented Bent SubThe oriented bent sub is use for the straight screw drilling tool getting into orientated. The oriented bent sub is
a tool use for deflecting of power drilling tools. Under the action of bent sub, a continuous lateral force imposed on the bit, and make the bit continuous side cutting wall of a well, drilled well body carve track. It has the advantages of simple structure, easy to use and low cost.

BYPASS VALVE
Multi-cycle Circulating SubsThe Multi-cycle circulating sub is a sub to provide cycle and
cooperate by dropping the ball several times. The operating steps of this tool is to achieve “shift” of product structure by dropping ball operation. It can generate a definite open or close position when dropping.
The drop ball cannot be pumped thru the tool during the cycle open function.
Advantage:1) The Multi-cycle circulating sub is the perfect tool for use
in high angle and horizontal wells.2) According to the standard, all tools have two large
circulating ports which greatly reduce the risk of plugging.3)The Multi-cycle circulating sub is the only tool that permits
full TFA reverse circulation.4)Due to the unique design of the Multi-cycle tool, the flow
ports are open before the activating ball reaches the catcher seat, in order to prevent the ball into the process being crushed.
5) The Multi-cycle circulating sub can be opened in a fixed position when it has run into the well bore.
6) The Multi-cycle circulating sub permit open and close at least six times, this number can be increased on request.
Our MCCS is widely use in Middle-East and Russia.
