AI Technical Summary

⚠Technical Problem

Existing guidance systems mostly use angular velocity sensors, which result in inaccurate data acquisition, untimely feedback from the tool face, and slow system response, leading to drilling deviation from the target center.

⚗Method used

The system adopts a fully rotary steering stabilization platform system, which integrates downhole instruments such as an acceleration acquisition unit, a fluxgate data acquisition unit, and a drive circuit. It collects data and transmits surface tool face setting commands through a central control module, controls the position of the upper and lower plate valves, and adjusts the drilling fluid flow rate in the flow channel.

🎯Benefits of technology

It enables real-time measurement and efficient closed-loop precise control of downhole tool face angle and well inclination angle. It features high data transmission rate and fast response, making it suitable for various application scenarios in the oil drilling field and reducing oil and gas extraction costs.

Abstract

The application provides a full-rotation guide stable platform system and an application method thereof. The system comprises a stable control module arranged on a downhole short section, which is in communication connection with an uphole system, receives and identifies instructions from the ground, detects tool face data of a downhole drilling tool in real time, and generates a control signal for controlling a control distribution module; a bus transmission module for transmitting the control signal generated by the stable control module to the control distribution module; and the control distribution module arranged on the downhole short section connected with the stable control module, which adjusts a disc valve in real time in response to the control signal, and stabilizes the relative position of a drill rod. With the system, the problems of inaccurate data and insufficient control accuracy in the prior art can be effectively overcome, the system has fast response speed and fast data transmission rate, is suitable for various application scenarios in the field of oil drilling, and has high practicability.
