TDS is one of the greatest technological revolutions of petroleum equipment which is used to replace Kelly and rotary table. TDS can drill with triples instead of singles which can reduce two-thirds volume of work of makeup and breakout and greatly increase drilling speed. The advantages of TDS is that in tripping if meets block up or struck, you can rotate the drill string while circulating mud flow so it can reduce drilling accidents. TDS can increase the level of mechanization of operation together with the wellhead system which can reduce the worker's labor intensity and the amount of operators. Especially in the directional well and cluster well, TDS has more advantages.
Characteristics:
Drilling tools can be hoist at any time and well bore can be cleaned during drilling to reduce accidents. In tripping if meets block up, you can connect the drill string quickly and circulate mud and make back reaming so that it can reduce sticking accidents.
