---------------------------------------------

Top drive drilling machine is one of the greatest technological revolutions of petroleum equipment, used to replace rotary table and may reduce the sticking accidents.

Features:

1. It can drill with triples instead of singles which can reduce two-thirds volume of work of makeup and breakout and greatly increase drilling speed.

2. The advantages of this system 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.

3. Top Drive System 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, Top Drive machine has more advantages.
