Measurement while drilling (MWD) for petroleum drilling

Customer Background

A Xi'an petroleum logging equipment company manufacturing MWD (Measurement While Drilling) systems for directional drilling needed high-reliability, high-temperature, high-vibration-tolerant accelerometers.

Challenges

• Downhole temperatures reach 150°C～175°C, requiring high-temperature tolerance.
• Drilling vibration and shock exceed 100g, demanding exceptional shock resistance.
• MWD systems require extremely high reliability; failure leads to costly tripping operations.

GyroSens Solution

• GyroSens provided quartz flexure accelerometers optimized for oil drilling applications:
• Proven quartz flexure technology with accuracy superior to MEMS.
• High-temperature design for downhole environment.
• Outstanding shock resistance (100g) for drill string vibration and impact.
• High-reliability design with MTBF meeting MWD system requirements.
• Analog or digital output options compatible with existing MWD interfaces.

Results

MWD systems successfully completed multiple high-temperature deep-well operations with toolface accuracy better than 0.5°, meeting wellbore trajectory control requirements and effectively reducing drilling risks.
