A well oil drilling consists of many oilfield drilling parts required to drill an oil well. The key parts include the following.
Drill bit
The bit is the part that actually drills into the ground, and it's designed to withstand high temperature and pressure.
Core barrel
The core barrel is an optional part of the well drilling assembly. If used, it will take cylindrical rock samples called cores to the surface. These rock samples are crucial to understanding the geology of the area being drilled.
Drilling fluid system components
Components of the fluids system include pumps, tanks, mud or fluid processing equipment, and pipelines. Normally, fluids known as drilling mud or drilling fluid are pumped down through the drill pipe and circulated back up through the annulus to lubricate the bit, cool it, and remove rock debris.
Drill pipe
The drill pipe is hollow steel pipe that provides the mechanism to drill down into the earth and also serves as a means to circulate drilling mud. The drilling mud also helps to keep the well unstable.
Drill collar
Collars are heavier than drill pipes used to add weight to the bit and ensure it drills vertically and straight through the target formation. The collars are tubular sections similar to drill pipes and are made of steel with a higher wall thickness.
Direct circulation drilling system
In this method, the drilling fluid is pumped down through the drill bit, which then returns to the surface through the annulus between the casing and wellbore.
Drilling rig superstructure
A drilling rig is used to drill the oil well and can be in-land, offshore, or vertically mounted on a mast. The parts of the drilling rig include its substructure, superstructure, and the rotary table on which the drill pipe is rotated. Another part of the rig is the hoisting cable used to lower the drill string into the well.
Surface casing
The surface casing of wells is normally set in depth and cemented to prevent water from entering the well or any hydrocarbons from seeping into the water.
Downhole tools
These tools are normally used as per the directional drilling method, wherein precisely horizontal, vertical, and angled wells are drilled. Special motors and bits are used to drill wells with an angle controlled by computer-based software from the surface to precisely target reservoirs deep underground.
Blowout preventer
Accidentally igniting oil or gas that spurts out of the well is known as a blowout. A preventer is a safety device used to prevent blowouts. It is a big stack of rams and seals installed on the wellhead of an oil well. Its main function is to control the high-pressure flow of drilling mud from the well while drilling into formations that may contain high-pressure oil and gas.
Parts of an oilfield that assist with the drilling process have unique specifications suited for their functions. Here are some of them along with their maintenance requirements:
Oilfield drill collar
Drill collars usually have massive and thick tubing. They are commonly made from steel and have outer diameters that range from 7 inches to 13 inches. Their lengths usually range from 18 to 30 feet. The weight of drill collars can be up to several hundred pounds.
Maintenance drills collars can be as follows: Use a lifting clamp that is suitable for the OD of the drill collar on the collar itself in order to maintain the drill collars during operations. Ensure that drill collars always remain in an upright position. Store drill collars properly, so they do not bend, twist or damage. Lower the drill collar slowly into the water in order to avoid any swing or necking down in the basket.
Bit oilfield drilling parts
An oil drill bit is the part of the oil drilling equipment that makes contact with the rock to create the hole. It comes in various shapes and materials to optimize the drilling process. Oil drill bits are available in different sizes to meet specific drilling requirements.
Depending on the style and material used, oil drill bits have different maintenance requirements. Usually, after use, they should be cleaned with high-pressure water. Before storing them, it’s better to coat the bit with anti-rust oil or spray to prevent surface rust. If the oil drill bit has a removable tooth, clean and dry it separately for better storage. Oil drill bits with damaged teeth should be repaired or replaced immediately.
Oilfield drilling mud pump part
Drilling mud pumps are available in various specifications to accommodate different drilling fluid requirements and pumping pressures. The specification of a drilling mud pump is typically determined by its stroke volume and pressure rating. For example, in a triplex mud pump, there might be 3 pistons with a stroke volume of 20.6 liters per stroke, while the pressure rating could be up to 5000 psi.
The mud pump should be inspected and maintained on a regular basis. During operation, make sure that the lubricating oil is enough in order to avoid pump body and plunger wear. Check the tightness of the conveying pipe and clamping part in time and tighten it with tools, when necessary, to avoid leakage or loosen during the conveying process.
Drilling rigs:
Offshore oilfield drilling parts, such as drill bits, collars, and casings, are essential for drilling rigs. Drill bits are the cutting tools of oilfield drilling parts, and their quality directly affects the success of drilling operations. Different types of drill bits are chosen based on geological conditions, such as roller bits and lamina bits. Drill collars are heavy pipe fittings used to keep drill strings stable and control drilling. They greatly influence the weight and stability of drill bits. Drill collars are typically made of high-quality steel with precise design to achieve the desired stability and weight.
Blowout preventers (BOPs):
The task of Blowout Preventers is to control wellhead pressures, seal wellheads, and avert oil or gas geysers, thereby safeguarding the safety of drilling crews, equipment, and the surrounding environment. The BOPs comprise an ensemble of oilfield drilling parts, inclusive of high-pressure preventers, control systems, and other pivotal components. Their selection and upkeep are conducted in strict adherence to established standards and norms to guarantee their functional integrity and reliability.
Drilling fluid systems:
Drilling fluid systems are a crucial component for offshore oilfield drilling operations. The primary function of drilling fluids is to perform tasks such as cooling and lubricating drill bits, transporting rock chips and drilling muds, stabilizing wellwalls, and preventing blowouts, among other vital functions. According to diverse geological situations and operational needs, distinct types of drilling fluids, including water-based fluids, oil-based fluids, and synthetic-based fluids, are adopted to guarantee the smooth progress of drilling tasks and uphold well integrity.
Directional drilling tools:
Offshore oilfield drilling generally adopts straight drilling, other methods like horizontal drilling and slant drilling are also applicable. Those techniques need special instruments, like drill bits with advanced technology, measuring and analyzing parts, and more, which assist in precisely directing the drilling orientation to reach the target reservoirs or enhance the efficiency of utilizing offshore spaces.
Workover rigs:
Workover rigs are the devices used to maintain oil and gas wells after they have been drilled. The parts of workover, like pumps, tubing, and downhole tools, are also classified as oilfield drilling parts. Because of the oil and gas reservoirs, the parts of workover rigs are used to extract oil and gas from wells, perform maintenance operations, and replace equipment as necessary. This helps to prolong the life of the wells and ensure their normal production operation.
