An Unbiased View of Drilling Rig Components
Stream line (#28) is big diameter pipe that may be hooked up towards the bell nipple and extends on the shale shakers to aid the move of drilling fluid again to the mud tanks.
It includes an annular variety blow out preventer and is particularly created to divert shallow gasoline clear of the well spot though drilling a surface hole. In doing so, the effectively stays open up, but diverting the tension avoids fracturing a development. Manufacturer specifications are:
TOP Travel is a drilling rig equipment which has been one of the greater improvements while in the oil discipline in the previous couple of a long time. The top travel procedure has a few major functions:
The BOP is simply utilised when the primary barrier (hydrostatic mud strain) has failed. Along with the bag preventer, a number of rams are used. The selection and sort of rams while in the BOP stack is determined by:
The surface diameter can be machined with helical grooves (spiral) to decrease the probable Get hold of floor for differential sticking avoidance.
Torque Indicator: The pull really should be utilized as perpendicularly as you can for the arm to prevent Untrue values.
To enhance efficiency, several rigs are equipped with two sets of Kelly bars for different geological circumstances.
throttling of mud, fuel, liquid hydrocarbons, and formation debris at any amount of circulation up towards the Actual physical capability of The inner circulation conduit.
This information relies largely or totally on only one resource. Related discussion can be found within the converse web site. Please aid increase this information by introducing citations Drilling Rig Components to additional sources.
For DP and DC make up torque values are indicated in API RG 7G. Two tongs are applied and positioned over the two Software joints. The best one is for the torque and the bottom one as being a backup tong.
Within a drilling rig Duplex Pump, the piston ingredient discharges mud on one particular side on the piston and at the same time can take mud in on An additional facet. Inside a Triplex pump, the piston discharges mud only when it moves ahead within the liner.
Desander / desilter (not pictured) includes a set of hydrocyclones that separate sand and silt in the drilling fluid. Usually mounted on top of the mud tanks.
Drill little bit (#26) is a device attached to the tip in the drill string that breaks aside the rock staying drilled. It is made up of jets through which the drilling fluid exits.
Operational Two tongs are used and positioned to the 2 Resource joints. The top just one is for your torque and The underside 1 is usually a backup tong.
The drilling line is reeved all-around this block, along with the touring block sheaves Together with the finish line about to an anchoring clamp Crown Block referred to as “DEADLINE ANCHOR.”
