Product Description:

OTR480D:

 

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.

 

 

Oil and natural gas drilling rigs are used not only to identify geologic reservoirs but also to create holes that allow the extraction of oil or natural gas from those reservoirs. Primarily in onshore oil and gas fields once a well has been drilled, the drilling rig will be moved off of the well and a service rig (a smaller rig) that is purpose-built for completions will be moved on to the well to get the well on line.[1] This frees up the drilling rig to drill another hole and streamlines the operation as well as allowing for specialization of certain services, i.e., completions vs. drilling.

 



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.
2.Takes international top CAT Diesel engine with electric injection, turbocharged and air inter-cooling system. It is high reliability, fuel economy and power reserves. Emissions meet standard EPAC-Ⅲ.
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:Classification of rotary drilling machines?
Classification of rotary drilling machines:Generally speaking, rotary drilling machines are divided into large, medium and small categories.The principle of choosing a rotary drilling rig should be to meet the current major engineering requirements of users and to take into account the possible engineering requirements in the future. According to the main working parameters of rotary drilling rig: torque, engine power, drilling diameter, drilling depth and the quality of drilling rig, rotary drilling machine can be divided into three types: torque 100kN = M. The power of the engine is 170kW, the drilling diameter is 0.5 to 1m, the drilling depth is about 40m, and the quality of the drilling machine is about 40t. This kind of drilling machine becomes a small rotary drilling machine, which is called a minicomputer for short.1, minicomputer application market positioning:(1) all kinds of slope pile blocks;(2) partial bearing structure pile of building;(3) urban transformation of municipal projects under various 1m piles;(4) piles for other purposes. Minicomputer market workload coverage rate of more than 30%.2: 180kN - m, midrange torque, engine power is 200kW, the hole diameter of 0.8 ~ 1.8m, drilling depth of about 60m, the quality of the drilling machine 65t.
Q:Price of small rotary drilling rig

Q:Construction steps of rotary drilling rig
The rotary drilling machine is in place and burying the protecting cylinder! When the bit is filled with soil sand material, the outer hole and the rotary drilling rig will be lifted
Q:In the middle of the 220 rotary drilling rig, sometimes the drill pipe slipped down 5~6 meters at work, as if the rope was broken. What's the matter?
If the wire rope drops suddenly, it is the power head faultThe drill pipe suddenly slipped, like the first floor, and the inside of the drill pipe was badly worn
Q:Wylong machinery rotary drilling rig in the use of the external power? How many volts does it take to drive?
The rotary pile driver is usually a spiral rod with diesel oil, and the pile driving machine has dual purposes of firewood and electricity
Q:My rotary drilling rig has broken several rotary drilling pipes. Is it my drill pipe or the reason of my rig?
To Wuhan Geological Engineering Machinery Co., Ltd. to buy drill bar.
Q:Does the rotary drilling rig need mud?
It needs mud and wall protection, and there are certain standards.
Q:How much money 220 daily rental price rotarydiggingmachine?
The mud circulation in different ways: rotary drilling mud usually adopts reverse circulation rotary drilling mud, which is usually not cycle.
Q:How can the drill pipe cracking of rotary drilling rig be welded?
