The moment of force also depends on the selected speed. The URB-2A2 dual-compressor drilling rig allows drilling in vertical and horizontal directions at a given angle. Drilling is carried out in several ways - auger, rotary with blowing or flushing. The presence of a control panel in the device guarantees comfortable and safe work for the operator. Advantages include a sensor system and full automation for high performance under all conditions.

Drilling rig URB 2A-2 based on ZIL 131

The URB-2A-2 exploratory drilling rig is designed for drilling geophysical and structural exploration wells for oil and gas using a rotary method with cleaning the bottom of the well by washing, purging or transporting the destroyed rock to the surface with augers. The installation has a moving rotator with a hydraulic drive, which is used in the drilling process, extending the drilling tool without removing it from the bottom and, together with the hydraulic lift, performs the work of lowering and lifting the tool and feeding it during drilling. Drilling is carried out using a rotary method with flushing or purging of the well or augers. The URB 2A2 installation is powered by the car engine. A hydraulically driven rotator moving along the mast is used when drilling, extending the drilling tool without detachment from the bottom and, together with the hydraulic lift, performs the work of lowering (raising) the tool and feeding it during drilling. The rotator moves along the mast using a hydraulic cylinder and a traveling system. The hydraulic mechanism for lowering and lifting and feeding the tool provides optimal feeding force, including when drilling with air hammers, and allows for highly efficient drilling in rocks of any hardness category. The installation control is completely hydraulic and concentrated on the driller's console. The control panel contains control devices and regulators for face force, feed and lifting speeds, as well as rotator spindle speed.

Main characteristics

This model is most often mounted on the ZIL-131 base. This is its standard equipment, which ensures increased maneuverability of the unit and a wide range of applications. The URB 2a2 model can be installed on a tracked or sled base. But this is additional equipment that must be ordered separately. The uninterrupted operation of the unit is ensured by the wheelbase engine. It is not able to function without additional equipment. The URB 2a2 model is completely manufactured using Russian technology from domestic spare parts. This reduces the cost of operating and repairing equipment.

This exploration-type unit can be used for drilling wells up to 300 m deep. It is also used to form channels designed to supply water, which can be used for drinking or technical purposes.

The advantage of the installation is that during operation simultaneous washing or blowing is carried out. At the same time, the drilling process itself does not stop. Also, the process of working with the URB 2a2 model is optimized, since the extension of the drilling tool occurs without separation from the face surface. The pipes are screwed in without additional mechanisms, which is very convenient. For this purpose, the model is equipped with a special rotator.

If drilling is carried out using pneumatic hammers, the optimal operating pressure on the bottom is maintained at all times. This is possible thanks to a hydraulic cylinder. This mechanism provides feeding, raising and lowering of the working tool.

The URB 2A2 drilling rig is designed for exploration drilling. It is worth noting that this particular installation has long become legendary among drillers and is in demand among consumers around the world. Engineering surveys, searching for minerals and water horizons, drilling for construction purposes - she can do everything. The installation can operate either as a continuous face using the roller cutter, auger or pneumatic impact method, or as an annular face using the core method. It works with a rotary type chisel, however, if desired, you can connect an auger unit. When auger drilling is used for not very great depths - 30-50 meters, the maximum depth of a structural exploration well drilled by such an installation is 300-350 meters, geophysical wells with flushing 100 meters, and geophysical wells with flushing 30-50m

Drilling rig URB 2A2: what are the advantages?

Drilling rigs URB 2A2 are simple and easy to use. The well is drilled using a rotary method, and it can be washed with a special solution or blown with air. The installation is mainly mounted on wheeled chassis “Ural 6x6”, “KAMAZ 6x6” or “ZIL-131”, as well as all-terrain chassis of the corresponding load-carrying capacity; its “heart” is the engine of the chassis on which it is installed. Hydraulic control greatly facilitates the work of operating personnel. The operator monitors the operation of the drilling rig according to the readings of control instruments, and controls it using regulators of the force of the lifting speed, rotation speed and bottom hole. Buying a UBR 2A2 means getting a universal drilling rig for performing a very wide range of work in drillability rocks of almost any category. Construction, water well drilling, engineering and geological research - it is the ideal solution for any task. Moreover, it can be installed on a four-wheel drive or sled chassis - it is simple and autonomous. Great demand gives rise to an equally considerable supply - services provided using the 2A2 URB drilling rig are becoming increasingly popular. It has been and remains a leader among Russian drillers in its class, thanks to its operational efficiency for more than half a century. This drilling rig has proven itself well even in the conditions of the Far North, as it is capable of operating on a tracked basis and even from a watercraft (drilling rig on a pontoon). This, as you yourself understand, is not something that every analogue can boast of.

Operating principle of the drilling rig

Let us consider in a simplified mode the operating principle of this installation. The drilling rig is driven by the chassis engine, then through the power take-off box installed on the chassis, mechanical energy enters the transfer case, two hydraulic elements (motor pumps) are installed directly on the transfer case, converting mechanical energy into hydraulic energy, one motor pump generates hydraulic energy energy for all hydraulic cylinders and provides hydraulics: mast lift cylinder, support cylinders, rotator lift and lower cylinder. The second pump motor provides hydraulics to the drilling rig rotator. A counter hydraulic element (pump-motor) is installed on the rotator, converting hydraulic energy back into mechanical energy. It is the rotator that transmits all the rotation to the drill string. A specialized competitive environment and reasonable customer requirements for drilling rigs, while maintaining low cost, helps to improve and modernize the design of the drilling rig. Our company offers you optimal and economically balanced solutions. And the use of the ISO 9001-2008 quality management system allows our company to release high quality products and unique service technology to the market.
