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:Attention problems of rotary drilling rig
Lubrication of slewing support gearThe supporting tooth surface shall be regularly removed and coated with the corresponding grease. Incorrect lubrication may cause damage to the slewing mechanism. When the grease in the slewing gear chamber is too long, the stirring loss will be increased and the deterioration of the grease will be accelerated. Deterioration of the grease will cause damage to the pinion and inner ring of the slewing gear. A shortage of grease leads to a deterioration in the lubrication of the gears. To avoid damage, make sure that the amount of grease added to the swing support is correct.
Q:What's the price of the 31 sr630rc8 rotary drilling rig?
Compared to other brands imported, Carter engine is poor. So buy the main part of Carter's 31. The price is not clear, should be in 4489
Q:What kind of stratum is suitable for rotary digging pile?
Core auger bit is suitable for crushed stone soil, medium hardness rock and weathered rock formation. Core rotary bucket, applicable to weathered rock and cracked rock.
Q:The overall structure and working principle of rotary excavation?
The mechanical device of rotary drilling rig mainly includes luffing mechanism, mast, main and auxiliary winch, power head, follow-up frame, pressurizing device, drill pipe, drilling tool, etc.. The parallelogram luffing mechanism, self lifting folding mast; automatic detection control of engine power, rotary positioning and safety protection: automatic detection and adjustment of verticality of drill pipe: the new technology of drilling depth preset and monitoring. Color screen display working state parameters, the control adopts pilot control, load sensing, maximize the convenience of operation, sensitivity and safety and comfort, the full realization of human, machine, liquid, electrical integration.
Q:If you have a project, will you make money from the auger rig?
Great profits, dry spin is the most afraid of lack of living
Q:Rexroth leveling sensor rotarydrilling rig
Intake air temperature sensorRole: provide air temperature information for correction of fuel injection and ignition timing. Effect: idle speed is low, easy to flameout.
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:Various types of rotary digging drill rod head size
Because the rotary digging into the sea China earlier, there is no uniform B by national standard, but the host plant is basically the same, but the difference is mainly divided into two types of schools: as schools, using standard rotary drilling chassis, the stability is good; 31 schools, using the general excavator chassis, stability has been lacking, but saves cost
Q:Types of rotary drilling rig
The principle of choosing a rotary drilling rig should be to meet the major engineering requirements of the user and take into account the possible engineering requirements. Rotary drilling rig can be divided into three types according to its main working parameters: torque, engine power, drilling diameter, drilling depth and the quality of drilling rig:Torque 100kN = M. The power of the motor is 170kW, the drilling hole diameter is 0.5 to 1m, the drilling depth is about 40m, and the quality of the drilling machine is about 40T. Application market positioning of minicomputer:
Q:For different geological conditions, how to choose rotary drilling, rotary drilling, impact drilling?
Rotary excavation is often used in the excavation of cohesive and sandy soil layers, but the efficiency is relatively high. But for rock foundation excavation, the requirements for rotary excavation equipment, especially the requirements of drilling bit and drilling rig, are very large.
