So in order to improve ROP, the VTK vertical drilling technology of Baker Hughes was introduced. VTK is a kind of closed loop, automatic, and vertical drilling technology, made up of closed loop rotary steering drilling system AUTOTRAK, high-performance X-TREME motor and reliable MWD. It is able to return the well path back to vertical by adopting downhole microprocessors to analyze the measured deviation data and determine the proper force necessary for decreasing the deviation angle to guide the steering rib at the high-side to reliably stick out against the upper wellbore.

为提高机械钻速，引进贝克休斯的VTK垂直钻井技术，它是由AUTOTRAK、高性能X-TREME马达、可靠的MWD三种技术开发出来的一种闭环自动垂直钻井技术，能够根据井眼的偏斜，经井下微处理器分析判断，使导向稳定地靠近井眼高边方向导向肋板伸出顶向上井壁，这样使钻头产生合理的降斜力，从而使井眼回到垂直轨道上来。

Then, aerodynamic parameters in different flight conditions are used to imitate the uncertainty of the system, and the digital simulation of closed-loop system designed is performed. The results show that the system can accomplish asymptotic decoupling of roll angle, sideslip angle and head-on angle for aircraft, and the system is provided with the function for restraining uncertainty in the system. This illustrates that the flight control system designed has not only good decoupling characteristic, but also better robustness.
