FAQ
Q: How about your after-sales services?
A: HELI has established a global 24-hour technical support network, providing remote diagnosis, on-site rapid troubleshooting, and preventive maintenance services. Through data analysis and lifelong technical training, it helps customers optimize drilling efficiency and reduce operating costs.
Q: What are the core functions of MWD system?
A: MWD system is capable of real-time measurement and transmission of downhole parameters to the surface during the drilling process. Its core functions include measuring wellbore trajectory parameters such as inclination angle, azimuth angle, and tool face angle, as well as monitoring engineering parameters such as formation pressure, temperature, drilling pressure, and torque. By quickly uploading these data to the ground control system, engineers can accurately adjust the drilling trajectory, ensure that the wellbore is drilled according to the designed path, and improve drilling efficiency and accuracy.
Q: Is the installation of MWD system complicated? Does client needs professionals?
A: The system adopts a modular design, and key components (such as probe tubes and pulse generators) must strictly follow installation specifications when integrated with drilling tools. It is recommended that they be operated by professionally trained engineers to ensure sealing, positioning accuracy, and data accuracy. After installation, ground debugging and signal testing are required. Our company can provide on-site technical guidance and training services.
Q: How to ensure the accuracy of MWD data?
A: The system is equipped with high-precision sensors, which have anti vibration and anti electromagnetic interference capabilities, and ensure data accuracy through multiple calibration mechanisms: zero and full-scale calibration must be performed on the ground before operation; During underground operations, the system automatically compensates and corrects for temperature and pressure; At the same time, the ground software will filter the received data, remove outliers, and ensure the reliability of the data.
