Small to medium-sized drilling rigs are mobile, such as those used in mineral exploration drilling, blast-hole, water wells and environmental investigations. Larger rigs are capable of drilling through thousands of metres of the Earth's crust, using large "mud pumps" to circulate drilling mud (slurry) through the drill bit and up the casing annulus, for cooling and removing the "cuttings" while a well is drilled. Hoists in the rig can lift hundreds of tons of pipe. Other equipment can force acid or sand into reservoirs to facilitate extraction of the oil or natural gas; and in remote locations there can be permanent living accommodation and catering for crews (which may be more than a hundred). Marine rigs may operate thousands of miles distant from the supply base with infrequent crew rotation or cycle.
OIL FIELD INDUSTRY BEARINGS
Mud pump is the drilling process, mud or water to the drill hole delivery of such as washing fluid machinery. Mud pump is an important part of drilling machinery. Its main function is to inject mud into the well along with the drill in the process of drilling, which ACTS as a cooling drill, cleaning drill tools, fixing borehole walls, driving drilling, and bringing the cuttings back to the ground after drilling. In common are circulating drilling, mud pump is ─ of the circulation medium in the surface water, mud or polymer rinses under certain pressure, through high pressure hose, faucet and center hole drill pipe column straight to the bottom of the drill bit, in order to achieve cooling the drill bit, to clear the debris that cutting down and the purpose of conveying to the surface. The usual mud pump is a piston or plunger type, which is driven by a power machine. With the alternation of suction and discharge valves, the paper realized the purpose of pressing and circulating washing liquid. Drilling machine overview: drilling machine is the main machine to complete drilling and construction. It drives drilling tools and drills to drill deep into the stratum, and completes auxiliary work such as lifting tools and casing, core extraction and drill replacement through the lift on the drilling machine. The main function of the pump is to transport washing liquid into the hole to clean the bottom of the hole, cool the drill bit and lubricate the drill. There are many kinds of drilling RIGS because of the different purposes and construction objects of geotechnical drilling engineering. Drilling RIGS can be classified by use, such as core drill, oil drill, hydrogeological survey and well drill, engineering geological survey drill, tunnel drill and engineering construction drill.
As the continues its drive towards energy independence, the oil and gas industry plays a vital role in the struggle to reach this goal. Every day American Roller Bearings are in service, operating under heavy loads that result from drilling deep holes into the earth - in search of gas and oil reserves.
Bearings Used in Oil Field Industry
We supplying large bearings for oil field drilling exploration for a long time. Types of equipment are mud pumps, swivels, drawworks, crown and traveling blocks, rotary table, blow-out preventers, and well service pumps. Usually, large cylindrical roller bearings with thin cross sections are used. Rotary tables use large thrust angular contact ball bearings.
