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:What are the polymer slurries used for rotary drilling machines?
Polymer polymer mud is a kind of advanced foreign technology imported product. It is a kind of water soluble and easy mixed powder granule polymer
Q:Construction scheme of rotary pile driver
Process selectionIn the construction of the project, the drilling method of rotary drilling rig and dry hole formation are adopted. Combined with the geological condition of bored pile in this project, many factors, such as large quantity and tight time limit, the backfill bit adopts rotary bucket drill, and the rotary digging sand drill bit is used in the cleaning hole. When rock is embedded, the bucket is drilled by rotary cutting, and the partially drilled sandstone is drilled by rotary auger bit. For some of the more abundant underground water piles, the slurry wall should be used as support, and the larger pile will be supported by steel support.
Q:What is a rotary drill for?
The unique power system, flexible moving mode, easy to learn operation, unique way of unloading sediment, and the diversity of functions are unique.
Q:How can the drill pipe cracking of rotary drilling rig be welded?
Or very good welding, and see what the substrate material. The shaft fracture can be welded. Tianjin source welding can be consulted.
Q:The difference between rotary drilling machine and rotary machine.
The mud circulation in different ways: rotary drilling mud usually adopts reverse circulation rotary drilling mud, which is usually not cycle.
Q:Can rotary drilling machine be used in rock layer?
Models are generally not available, and large torque can be used for rocks that are not too hard. Rotary drilling rig is suitable for pumping out formation.
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:What brand of rotary drilling rig is efficient?
The working efficiency is high, the domestic rotary drilling rig is relatively good in the Futian leiwo rotary drilling rig, driving very fast, with less, I was in Linyi, bought the first 09 years, 11 years and bought 2, now 3, around the project.
Q:What's the difference between rotary drilling rig and rotary drilling rig? What's the model?
Essential difference: 1, mud 2, move 3, drill pipe 4, drive 5, efficiency
Q:What is the minimum diameter of a bored pile?
The minimum diameter of the rotary bored pile is 670mm, the drill bit diameter is 600mm, and the actual drilling hole is 670mm.
