A drilling rig is a machine which creates holes in the earth sub-surface. Drilling rigs can be massive structures housing equipment used to drill water wells, oil wells, or natural gas extraction wells, or they can be small enough to be moved manually by one person and are called augers. Drilling rigs can sample sub-surface mineral deposits, test rock, soil and groundwater physical properties, and also can be used to install sub-surface fabrications, such as underground utilities, instrumentation, tunnels or wells. Drilling rigs can be mobile equipment mounted on trucks, tracks or trailers, or more permanent land or marine-based structures (such as oil platforms, commonly called 'offshore oil rigs' even if they don't contain a drilling rig). The term "rig" therefore generally refers to the complex of equipment that is used to penetrate the surface of the Earth's crust.

 

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.

 

 

1. Adopts the complete OEM Caterpillar retractable-crawler dedicated chasis,Its telescopic scope between the two crawler ends extends from 3000mm(at transportation) to 4400mm(at work). Undercarriage with expandable and removable tracks by means of hydraulic cylinders, guarantee exception stabbility in any type of ground. It has considerable traction force which allows easy movement even in the most difficult job sites.

3.The winches are positioned in the lower part of the mast, in front of the cabin, so that the operator can constantly check the proper operation. Thanks to the fact that the cable moves parallely to the mast, flection is not created on the upper part of the mast and operating life of the cable is therefore much longer. Tail positioned winch is available for heavy-duty type.
4.New design parallelogram system, computer optimized design and simplified pin connection system featured with nice appearance, great driving force and good stability, especially shaped to fit crowd system, allowing working radius adjustment always maintaining the mast in vertical position. The parallelogram system is easily for convenient transform between transportation and working conditions.
5.Self-erecting mast, high level anti-shock technology and high-strenth material steel attribute to that max torque can be applied all over the mast length. Multipurpose design for cylinder crowed system. Sensor and control center realize real-time measurement of the inclination angle, auto adjustment of mast verticality and inching adjustment.
6.Crowd system by means of long stroke hydraulic cylinder or crowd winch separately, are option for your exact request.
7.Rotary head with variable displacement motors and one high spin off speed. And rotary is extremely reliable, it has been disgned in order to gurantee a very compact, efficient and powerful rotary. The transmission group of rotary is made up of a hydraulic motor and new power shift purposely studied and designed to obtain maximum perfomance. During the drilling phase, the rotary has the entire power of the diesel at its complete disposal. Adapter of rotary is essential to absorb the considerable shock connected to the high speed of the main winch.
8.Telescopic kelly bar with guide made by high quality specially for high boring strength and torque force. Available with friction or inter-locking type.
9. All the main hydraulic components(pumps, valve, motor, connector) are from well-known international brands such as Bosch-Rexroth, brevini, which ensure the stability, reliability, high-efficiency and energy-saving of the entire system
10.Electronic controlling system is an innovative system, developed by Osaint, which controls and monitors the operation of the machines. For ease of operation, the system is controlled by a touch screen located in the cab. The system function is to enable the machines to perform different functions more efficiently. A dedicated power module electronic control and CAN-Bus system ensures the main pumps and Disel engine to work at their most effective and productive stages.

Q:Can the auger drill be drilled into the two - longest granite of the 1200kp?
Drill the special effort, we have the hardest to 900kp, take the drill, hold up, are a large column, an hour about 2 meters into the rock. Hard, then the hole time is very long, slowly grinding.
Q:200 rig footage every day how many meters
Footage number and geological conditions, drilling performance, operator proficiency, construction site conditions have a relationship, and to say that footage of the day, and the length of pile pile diameter has a diameter of 1.2 meters, with 60 meters long, 2 meters under the casing 0.5 hours, casing well Party A, the Commissioner General to look at. General situation, the first 20 meters of drilling, probably within 1 hours, 20-40 meters, less than 1.5 hours, 40-60 meters, less than 2 hours.
Q:What are the reasons for partial drilling of rotary drilling machine?
Drilling bucket: the main function of drilling bucket is cutting and drilling, but it also has the function of guiding and preventing deviation. The pilot base drilling bucket with positioning function, at the same time the pilot pointed tip can be changed into order, and the number of teeth of the drill view is not common, the drill body on both sides of the knife or door bar height is not common, these details can make drilling bucket drilling about uniform stress and prevent error.
Q:What are the differences and relations between machine, trenchless drilling rig, horizontal directional drilling machine and rotary drilling rig?,
The rotary drilling machine seems to be laying foundations for example when building a house, digging a hole with a rotary drilling machine and pouring it into the concrete.
Q:What brand of rotary drill is good?
Abroad, Bauer, I used the Futian leiwo, is awesome, Carter chassis, three motor reducer, power head multi speed control, embedding ability of super strong, often machine is an open day.
Q:On the cleaning of rotary drilling rig
Rotary drilling, which meet the design requirements when the rotary drill is a few laps and idling; after several hours of the cage and the catheter after the hole and some sediment, have to clean the hole, now called the two hole cleaning. However, with the development of science and technology, the popularization and application of new technologies and materials. With the new wall protecting liquid, not only the wall is well protected, but also the hole and the sediment behind the cage seldom meet the requirements, the two cleaning procedures can be omitted, and the pile forming speed is greatly improved. For example, we use the Montreal chemical mud in construction after the Zhengzhou Xinzheng Airport, nearly 70 meters of sediment pile placed for 2 days no more than 20 cm. It brings great convenience to the construction.
Q:Rotary drilling rig GPS unlock?
This method is actually the simplest one for most Android phones. Before the operation, you only need to shut down mobile phone, and then press the volume + or - when rebooting (different brand mobile phone may differ), while holding down the power button, you can enter the Recovery mode. Go to Recovery mode and select Restore factory.
Q:For different geological conditions, how to choose rotary drilling, rotary drilling, impact drilling?
Such a soil condition, it is not recommended to use rotary drilling rig. The upper soil can be drilled with a rotary drill, and an impact drill can be used after the formation of rock.
Q:What is the essential difference between rotary drilling rig and rotary drilling rig?
English is rotary drilling rotary drill rig, in addition to the configuration of various rotary bucket operation, installation of casing drilling, with rolling tube device and grab for will casing construction; with telescopic guide rod grab underground continuous wall construction, with DTH of hard rock crushing construction; operation device can also be replaced for jet construction and circulation of construction; construction of pile foundation can also configure other forms of hydraulic hammer, diesel hammer etc..
Q:What brand is the best for rotary drilling machine?
But domestic drilling rigs have high performance price ratio. In the late use, equipment will inevitably fail, and domestic brands of timely service is good.
