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:Can the auger drill be drilled into the two - longest granite of the 1200kp?
Depends on the power of the machine
Q:Rotary drilling rig deep hole Doumen difficulties what happened?
Cobble formations, which carry out drilling and collapse, are very difficult formations
Q:What kind of hydraulic oil is used in XCMG XR220 rotary drilling rig?
Rotarydiggingmachine fever is a normal phenomenon, but if serious account of hydraulic oil filter through the difference, the best choice for Shell Tellus s2m46 oil
Q:Construction scheme of rotary pile driver
Overview of drilling hole of rotary drilling machineAccording to the geological conditions of this project, and design requirements, combined with the pile foundation design parameters and requirements of the owner, the engineering pile drilling technology using rotary drilling rig, concrete using commercial concrete and steel reinforcement cage hoisting welding forming, lashing, catheter perfusion underwater concrete.
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:Rotary drilling rig on the floor under the floor with steps
Back on the truck, slowly, especially when the center of gravity. In short, pay more attention to it! Before loading, the machine must be adjusted to the state of transport, on the trailer when the spiral digging back up, down the trailer when it is good, straight down. Obey the command, careful driving, generally no accident.
Q:Does the rotary drilling rig require a national issued operating permit?
Of course, you need to go to the safety supervision department for processing, the cost is about one thousand yuan, the training fee is extra. My relatives have done a rotary drilling rig operation card, and now earn seven thousand or eight thousand pieces a month.
Q:What bucket teeth are used in rotary drilling machines?
We use the site above alloy bucket tooth, tooth special rotary drilling rig alloy, durable many times more than ordinary tooth Oh, but the price is several times more expensive than ordinary, but together, but it is still very good, after all, little change in time, save a lot of trouble.
Q:Rotary drilling rig application
The purpose of rotary drilling rig is cast-in-place bored pile drilling (Cheng Kong).
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.
