TDR -50 is mainly used for coal bed methane exploration, water well drilling, rescue well drilling,
shallow oil and gas, mine exploration drilling etc.
The TDR-50 multifunction top drive rig enables each user to drill with following methods, with borehole
diameters of 4” (108 mm) to 47” (1200mm) and drilling depths up to 1500m
l Rotary-drilling with direct circulation
l Rotary-drill with reverse circulation
l Auger drilling
l Percussion core drilling(ram coring)
l Wire line core drilling
l Down-The-Hole hammer DC and RC drilling
Drilling Depth Guidelines:
Use 5” rod 600 – 1 000 m
Use 4-1/2” rod 800 – 1 300 m
Use 3-1/2” rod 1 000 – 1 500 m
The figures in these tables have been calculated, based on field experiences, based on a vertical, straight, and clean down hole. Actual drilling capacity depends on in-hole tools, conditions, drilling techniques and equipment used.
Main Components Description:
The TDR-50 which is assembled by FORWARD Heavy Instruction Machinery Co., Ltd, is mounted on the undercarriage of excavator with a total weight of 35 ton. The engine power 243 Kw.
Constructed of high tensile steel and hydraulically elevated, mast lifting and lowering and degree of slope controlled by four (4) double acting hydraulic cylinders. The mast is equipped with 4 guide rails for the carrier of the drill head and a suspension for the feed device. The rig is also equipped with slipper system, in order to the mast slip, and the stroke is 3.65m, the mast can be reliably based on the ground. The rig can be set up the blowout preventer and other systems.
Mud Line System:
All mud lines on the TDR-50 Drilling Rig have 3” (76.2mm) diameter, in order to reduce friction losses to a minimum.
Top Drive head:
Top drive head suits for tricone bit, DTH hammer, PDC Drill bit and diamond bit which meets special demand of rotate speed and torque during work. The 4-shift Gearbox using spur gear drive, oil bath lubrication. Hydraulic Motor and gearbox could provide for much high speed and torque to be adjusted. The angle of rotate unit could be adjusted as needed, ranges from 00 (vertical) -900. The water connector can hold a pressure maximum 35Mpa.
Generator and battery are driven by diesel engine and provide 24V direct-current power supply. All cables are protected with seal line. Furthermore, all circuits are equipped with short-circuited plunger.
Additional Rig Components:
TDR-50 Rig can be modified. All kinds of aggregates, required for different drilling methods, can be installed on the rig at customer request, or supplied as stand-by aggregates.
