GB/T 45134-2025 is the English-translated version of 石油天然气钻采设备近钻头地质导向钻井系统.

GB/T 45134-2025 is the Chinese national standard covering the measurement sub that sits behind the bit and steers a well by what it reads there — the downhole device and its classification and model designation, the resistivity measurement and the sector readings that tell which side of the hole the bed lies on, the engineering parameters, the vibration and impact testing, the lithium battery and the explosion protection, the theoretical build rate, and the inspection rules. First edition, in force from 1 August 2025. Issued on 24 January 2025, it has been in force since 1 August 2025.
