- Top Drive System
- JH developed the top drive drilling system with independent intellectual property rights. It integrates the mechanical, electrical and hydraulic control technologies. JH top drive drilling system takes a full advantage of operations while drilling. The JH top drive drilling system has the advantages of simple structure, easy operation and long service life. All the above features fully satisfy the technological requirements of drilling rigs. It is essential equipment for the drilling of deep wells, super deep wells, horizontal wells as well as controlled directional well in complex geologic condition.
Main technical features:
01. Adoption of a double cylinder opposite clamping type backup tong, it can makeup and breakout without locking the rotating link adaptor. It is more applicable, convenient and easier to handle, allowing makeup and breakout to be fast and easy.
02. The patented structure of rack and pinion used in IBOP of the hydraulic controls allows for the hydraulic pipe to be embedded into the body of structure in order to avoid the damage of the hydraulic pipe during bumping. This makes the operation of IBOP more reliable.
03. The patent slid-inset type foldable structure is used in the guide beam. It is quick, convenient and safe to install and dismantle when comparing with the other brand top drive drilling systems. Installment time of our guide beam could save 2~3 hours.
04. The patent structure of reversed oil cup used in the main shaft seal of the gearbox guarantees that the lubrication will not leak in the process due to the seal of the main shaft being out of order.
05. The Driller panel is equipped with a touch screen this displays the condition of system operation and can also monitor emergency point of equipment in real time it also increases the reliability of equipment operation.
06. The counterbalance system with patent technology adopts double cylinders, which provides excellent balancing performance.
07. The system is equipped with a double PLC control systems, which provides redundancy in PLC controls. This design greatly improves the reliability of our top drive drilling system.
08. The hydraulic system is integrated on the main body of top drive, it is convenient to installment.
09. The anti-loosen device with single direction tong dies can load more torque and be installed and disassembled easily.
10. All the cables adopt integral protection, which improves the mechanical strength of cable and increases the reliability.
11. The rotating link adaptor connects with the gearbox through shaft sleeve. When raising and lowering drill pipe or making a break off with bumper jars, there is no force on the main shaft, which increases the service life of the main shaft bearing.
12. With our patented technology of casing running tools, during a casing run, it provides protection if pipe sticks or a well kick happens, it can also assist in the fast connections of top drive and casing pipe, allowing cycling of the mud. This helps avoid accidents (customer optional)
13. Our drives, when equipped with the trolley of slips including the pneumatic lift device will reduces labor intensity, and increased drilling speed (optional).
Advanced Technologies of JH Top Drive
Soft Torque Technology£º
Automatically identify working conditions, adjust the output torque features, and effectively mitigate the incidence of stick slip and downhole vibration. Speed up rock breaking, reduce drill string malfunction and bit wear, prolong the service lives of drilling string and bit.
Shaft Rotating Control Technology£º
Accurately control rotary direction, number of revolutions or angles of top drive main shaft, adjust the tool face and location angle of drilling string as of directional drilling. Improve the azimuth control accuracy and optimize well track.
Top Drive Casing Running Technology£º
