| High Light | Electric Top Drive Drilling System ，250 Ton Top Drive Drilling System ，500 Ton drilling rig top drive system | ||
The top drive device directly drives the drilling tool to rotate and drill from the top of the derrick. It can directly rotate the drill pipe above the derrick , extend the special track downward and upward , and complete drilling operations such as rotation , drilling , circulating drilling fluid , connecting drill pipe , repairing broken pipe , and post-expansion. The top drive drilling device is the cutting-edge technology and equipment for oil drilling today , and is one of the three major technological achievements of modern drilling equipment (AC/DC variable frequency electric drive system and downhole drill bit booster system).
The top drive drilling system has now become a standard product in the oil drilling industry. It has a wide range of applicability , and the top drive drilling system can be used for wells from 2 , 000 meters to 9 , 000 meters in depth.
The top drive drilling system produced and sold by our company Huichi Petro is generally composed of the main body , electrical transmission control system and hydraulic transmission control system.
Power faucet , pipe handling device , VFD or SCR , PLC , operating table , guide rails , etc.
Power faucet: drives the main shaft to rotate and drill.
Pipe handling device: grab and release drill pipe , make and break out , control IBOP> electrical control system.
VFD or SCR: provides power for the main motor and regulates torque and speed.
PLC: controls and monitors speed , torque and the actions of each actuator , and controls , interlocks and protects according to logical programming.
Operating table: the driller controls the actions of each part.
The hydraulic transmission and control system provides hydraulic power , transmission and control of each actuator.
Guide rail: bears the anti-torque of the top drive main body.
2.Others:
Wellhead centralizer , casing device , logging device , detection tools and instruments , etc.
Top drive working interface: mechanical part , electronic control part , hydraulic part.
Gear transmission adopts involute hardened gear , and special material is processed by grinding and shaping.
1.The process of drilling and drilling is simple , installation and maintenance are simple , and the operation is convenient and flexible. The top drive is composed of several parts such as power unit , tilting device , pipe handling device , torque tube , etc. It is simple to operate , easy to disassemble and assemble , flexible and reliable;
2.Safe operation.Since the top drive adopts column drilling , the total number of single-root connections is only 1/3 of the usual number , which greatly reduces the danger of the operator's work.
3.If the top drive is used , it is easy to use the power faucet on the drill string to rotate the drilling tool to circulate the drilling fluid at any time and any position , which greatly reduces the complex situation such as stuck drill;
4.Save auxiliary drilling time and improve drilling efficiency. Each column drilled saves more than 2/3 of the auxiliary time compared to the conventional rotary drilling rig. A large number of practices at home and abroad show that the use of top drive can reduce drilling time by 10% to 30%;
5.It is particularly suitable for drilling directional wells and horizontal wells. The drilling capacity can be significantly improved compared with the conventional rotary drill with the same drilling capacity , thereby greatly reducing the drilling cost;
6.Standard: API SPEC 8C standard.
Oilfield Well Drilling , Energy , Mining.
