Drilling rigs, or drilling rigs, are mechanical equipment for drilling holes on the surface. Drilling rigs include outdoor drilling equipment for large water wells, oil wells and natural gas wells. It also includes small devices that can be moved by a single person, called augers.
Drilling rigs can sample underground mineral deposits or be used to install underground production equipment. Such as underground machinery, instruments, pipelines and hoistways. DTH drilling rigs can be mobile equipment installed on trucks, trailers, or tracks.
Drilling rigs can also be relatively fixedly installed on land and offshore structures (such as drilling platforms, which are generally referred to as "offshore oil rigs", although they do not include drilling rigs). The term "drilling rig" generally refers to equipment that drills into the earth's crust.
The YG drilling rig machine includes
Small portable drilling rig. Such as mining drilling, water wells, environmental survey drilling rigs.
Large-scale drilling rigs can drill the earth's crust to a depth of more than thousands of meters. During the drilling process, the mud pump circulates the mud through the drill pipe and the drill bit into the casing annulus to cool the drill bit and remove cuttings.
The lifting system on the down the hole drilling rig can lift hundreds of tons of drill rods. Other equipment can pump acid or sand into the reservoir, perform fracturing operations, and guide crude oil or natural gas out of the reservoir to the surface. In remote areas, drilling rigs can be equipped with permanent residential facilities, eating tools, etc., which can be provided for the daily lives of more than one hundred employees. Offshore drilling rigs can operate at a distance of several hundred kilometers offshore, and personnel on the water well will rotate.
Drilling rigs are classified according to drilling type
Because different drilling types allow drill rods to enter the borehole in different ways, each has advantages and disadvantages. According to the depth that can be drilled, sampling type, cost, and insertion rate, there are two basic drilling types. : Cuttings drilling and core drilling rig machine.
Spiral drilling Rigs
Spiral drilling uses a spiral drill to rotate into the ground, and the soil is lifted to the ground through the gap of the spiral blade. Hollow drill pipes can be used for drilling, geological drilling, soil engineering and geochemical exploration of mineral deposits in soft soils such as swamps and other soils where the soil does not open naturally. Solid flying drills/short tube augers are used for hard soil drilling. Sometimes, mining shafts are drilled with auger rods. Small drill rods can be installed on trucks, and large augers can be used to place bridge foundations.
Spiral drill pipes are generally used for relatively soft unconsolidated materials or rocks in bad weather, and are characterized by economy and speed.
