Product Description:

 

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.

 

There are many types and designs of drilling rigs, with many drilling rigs capable of switching or combining different drilling technologies as needed. Drilling rigs can be described using any of the following attributes:

 

By power used[edit]Mechanical — the rig uses torque converters, clutches, and transmissions powered by its own engines, often diesel

Electric — the major items of machinery are driven by electric motors, usually with power generated on-site using internal combustion engines

Hydraulic — the rig primarily uses hydraulic power

Pneumatic — the rig is primarily powered by pressurized air

Steam — the rig uses steam-powered engines and pumps (obsolete after middle of 20th Century.)

 

 

 

OTR840D:
①. Base: CAT 329D(HHP)
②. Max pile diameter (mm): 1800
③. Max pile depth (m): 60
④. Engine: CAT C7 ACERT 187KW
⑤. Maximum nominal torque (kNm): 200
⑥. Undercarriage with expandable (mm): 3000-4300


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:Is the rig operator tired?
Rotary drilling rig construction is generally 24 hours continuous, machine hand generally two people, day and night shift every 12 hours to eat, deduction and engineering intermittent, not tired. However, basically field construction, night work hard point. Salary is about 5000.
Q:The Montreal rotary drilling mud powder special effect is good
The Montreal chemical slurry quality.Zhengzhou 107 road viaduct construction are used in Montreal chemical slurry! Good shelter and little sediment.
Q:Are our common rotary drilling rigs the same as those for well drilling machines?
A dozen meters of drilling hole, is to drink water, drink water to break the stone, no stone rig also never mind, in Loess
Q:What brand of rotary drilling rig quality is better? How much? How long is it back?
At present, the domestic rotary drilling rig manufacturers are also many, good and bad, good and bad. Large enterprises such as 31, CSR, China United, Xugong, mountains and rivers, Jintai and so on, there are many small enterprises, not one by one examples. We recommend rotary drilling rig for 31 and csr.
Q:How many types of rotary drilling rigs should be used for entering ten meters of weathered sandstone in the rock?
I now have a 31 SR280R rock drilling machine, hit ten meters of weathered sandstone, the estimated efficiency is not high, I suggest you can use 31 rotary drilling rig SR285RC8 or combination rotary drilling rig ZR360.
Q:How to distinguish the performance of rotary drilling rig?
It adopts box type structure and has built-in clapboard to strengthen it. It has strong rigidity and good stability, and ensures the resistance to bending and bending. The whole mast is hinged with four sections and three sections, so that the overall size of the whole machine is minimum, so that it is easy to transport.
Q:XCMG XR360 rotary drilling rig generally how much?
5 million 700 thousand standard 508 drill pipe, section five 77 or four Mimo resistance pipe, section 62 meters machine lock, two optional one
Q:What brand of rotary drilling rig is efficient?
Has the product mix 12 tons - 28 tons of rice rice full range of Futian leiwo rotary drilling rig, with large 85m 2.5m large drilling depth, pile diameter, the parallelogram shaped international popular amplitude structure, flexible action, amplitude range, high construction efficiency.
Q:How much money 220 daily rental price rotarydiggingmachine?
Different drilling principle: rotating drill through the rotary drive pipe, and connected by drill bit cutting rock, rock chip cutting down the drain hole through the mud circulation; and the rotary drilling rig is through the first power driven drilling bucket digging, drilling bucket filled with soil after the hole dumping, this repeated cycle into the hole.
Q:What is the minimum diameter of a bored pile?
The minimum diameter of the bored pile is 310 mm;
