The TDS-200 machine mainly consists of two major components: a power faucet and a pipe processing system. The power faucet mainly includes: main motor system, main bearing mechanism, and central mud channel; The pipe processing system mainly includes: backup pliers, rotating heads, lifting ring tilting devices, etc. The auxiliary system mainly includes: guide rails, pulleys, VFD control room, PLC electrical control system, hydraulic station, drilling control console, etc.
As the latest drilling method, there are many advantages that differ from square drill pipe drilling. Compared to previous methods, the top drive drilling device has some specific advantages:
1. Save time on receiving individual cables
The top drive drilling device does not use a square drill pipe and is not limited by the length of the square drill pipe, avoiding the trouble of connecting a single drill pipe when drilling around 9 meters. Instead, the use of column drilling greatly saves the time for connecting individual pipes, thereby saving drilling time.
2. Reverse drilling to prevent sticking of the drill bit
The top drive drilling device has the ability to use a 28 meter column for reverse drilling, which can smoothly circulate and rotate the drilling tool out of the wellbore without increasing the drilling time. During directional drilling, the total drilling time can be significantly reduced.
3. Drill down and make a hole
The top drive drilling device has the ability to drill through sand bridges and reducing points without disconnecting the square drill rod. When using the top drive drilling device to drill, the drill string can be connected within a few seconds, and the hole can be immediately drilled to reduce the risk of sticking.
4. Personnel safety
The top drive drilling device can reduce the number of single connections by 2/3, thereby reducing the incidence of accidents. To connect a single piece, you only need to use backup pliers. The tilting device on the unloading device assembly of the drill pipe can swing the lifting ring and elevator downwards to the mouse hole, greatly reducing the danger level of personnel's work.
5. Equipment safety
