- W2517852812 abstract "Automatic deviation control and straight drilling is one of key technologies to ensure the drilling quality during vertical wells drilling, which requires systemic design and analytical theory for the automatic vertical drilling tool. The suspension structure design of rotation control shaft with fully seal has been adopted in the automatic vertical drilling tool based on force pushing principle. The engineering prototype of automatic vertical drilling tool has been developed. The simulation experiment for key units such as hydraulic assigned valve, torque generator, the monitoring and controlling system of stabilized platform, and water drilling on the ground of automatic vertical drilling system has all been finished successfully. The field experiment has indicate that the control ability for inclination of automatic vertical drilling system has reached to 1.2°, and time between failures is more than 200 hours in the field test. The drilling tool of automatic vertical drilling system that assembles mechanical electro-hydraulic system can achieve deviation control actively in easily-inclined formation such as high dip angle, irregular ground stress, and greatly liberate drill pressure, improve drilling speed and reduce drilling costs." @default.
