Rig floor tools and equipment

There are two types of equipment on the roof of the tower, thefirst is used to lift and grab the other and the opening of drillpipe during pull out and going down.

1 - Lifting equipment

The hook (hook) on the side of a tool called an elevator Andthat each tube (elevator) of its own, according to outerdiameter.

In the case of pipes relates its weighting on the tube called aspecial piece (SUB) has the same diameter drill pipe is notforced to change the (elevator).

In the case of raising the drill string and when you need toopen the (elevator), there Stomach special called sliders

(slips).Consists of several jaws and contains the sheet metal gear

made of special materials called disk. mission pressure on thepipe passing through the inlet (RT) to prevent sliding insidethe well while opening the (elevator).

In general there are two types of the (SLIPS), a special typedrilling pipes and special pipes weighting.The first type (for PAL DP) consists of three cone-shaped jawsand upside down makes a ring around the tube and all thedecoder contains three columns, each column contains sixdisks which is the total 54 disks.

The second type (for PAL DC) consists of 9 jaws and eachone contains 7 disks, but given that the pipeline weighting besmooth from the outside and weight of the large, he must belinked to clip a special safety named (Safety clamp) andconsists of 8 jaws and small container on disk. but ischaracterized by the existence of a special screw to give it astronger pull on the tube.

2-equipment tensile opening hand:

The pulling drill pipe or weighting with each other and theintention is sufficient to prevent opening during reverse

circulation inside the well using a special multi-key jaws.It is a key length of 125 cm almost three jaws one of whichcontains Daesen The jaws close together others containsevery one Dees only one.There are two keys on each floor tower and one other left andright, connecting the first end of the tube first (Pin) and thesecond key to the beginning of the tube the other (Box) andderives the key to every movement of the (DW).

And each key is hanging wire to wire in force at the tip of theother there is weight to facilitate the movement of key up anddown.

A key to open the air tight pipe, but does not give enoughtorque during stretching, but the advantage of fps speed

during tensile wire to be hung in force when the spring lengthof one meter. It is possible to switch his wheels to suit various

sizes of drill pipe.

There is the (chain tong) are used to decode the link and(Kelly) with the drill pipe but does not provide a large torque

depend on the strength of the WorkingUsed to flatten the tubes fast because the key weighting theantenna is not suitable for the outer diameter of the pipeweighting.

3-Rotary table (Rotary table)

This mechanical device is very simple and requires only littlemaintenance, and this makes it very suitable for working

conditions on the tower.The maintenance of rotary table is in check the level of fat inthe lubricating systemWhile drilling the weight suspended by hook but when you putthe sliders (Slips) be a weight hanging over the (RT) only.The rotary table in the Tower (EMSCO) is not available whenthe engine of its own, but derives its movement by movingwith the chain drives the (DW), it is possible to increase ordecrease the speed according to the needs Digger.There are several measurements of the rotary table (17.5 &

20.5 & 27.5 & 37.5 & 49.5).In the tower (EMSCO) Measuring rotary table 27.5 Wang.
