Introduction to Rotary Drilling Rig Accessories
Rotary drilling rigs are critical in the extraction of oil and gas, requiring a variety of accessories to ensure efficient and safe operations. These accessories play a vital role, impacting the performance, safety, and cost-effectiveness of drilling activities. This article details the essential accessories used in rotary drilling rigs, including solutions provided by SUPERPOWER MACHINERY.
Drill Bits
Drill bits are the cutting tools used to crush or cut the subsurface rock formations. Common types include roller cone bits, diamond bits, and polycrystalline diamond compact (PDC) bits. Selection of drill bits depends on the rock hardness, formation characteristics, and drilling program. For example, rock hardness is measured on the Mohs scale, where a hardness of 7 typically requires a diamond bit.
Drill Pipes
Drill pipes are critical in transferring drilling fluid to the drill bit and transmitting rotary motion. These pipes are available in varying diameters, commonly ranging from 2 3/8 inches to 6 5/8 inches, and lengths up to 31 feet. The pipe's thickness and grade dictate its strength, often measured in pounds per foot.
Kellys and Kelly Bushings
Kellys are long, square, or hexagonal steel bars that turn the drill string. Kelly bushings interface the kelly with the rotary table, turning the kelly as the table rotates. Kellys usually extend 40 feet and vary in diameter, with a typical range of 3 to 6 inches.
Mud Pumps
Mud pumps circulate drilling fluid under pressure, clearing cuttings from the wellbore and cooling the drill bit. The performance of a mud pump is characterized by its flow rate, measured in gallons per minute (GPM), and pressure rating, often measured in pounds per square inch (PSI).
Shale Shakers
Shale shakers separate drilled solids from the drilling fluid, using mesh screens to sieve out particles. Screen mesh size, typically measured in meshes per linear inch, directly impacts filtration efficiency, with common sizes ranging from 80 to 200 mesh.
Blowout Preventers
Blowout preventers (BOPs) are critical safety devices designed to seal, control, and monitor oil and gas wells. The pressure rating of a BOP, often between 5,000 to 15,000 PSI, is a key parameter in its selection.
Rotary Tables
Rotary tables facilitate the rotation of the drill string during drilling. Their diameter, typically between 37.5 inches to 60 inches, determines their compatibility with other drill components and influences the overall capacity of the rig.
