The High-speed Pulser MWD System is built around advanced continuous-wave drill-ing fluid pulse transmission technology, enabling stable, real-time, high-speed trans-mission of engineering parameters (inclination, azimuth, toolface, etc.), geological parameters (gamma ray, resistivity, etc.), and environmental parameters (tempera-ture, pressure). Compared with conventional technologies, this system significantly improves data transmission rate and reliability, ensuring that surface engineering teams can obtain accurate and comprehensive logging-while-drilling data in real time. This allows faster drilling decisions, wellbore trajectory optimization and geo-logical risk identification, ultimately improving drilling efficiency, ensuring operation-al safety and increasing reservoir encounter rates.
Ø Using continuous-wave (CW) pulse coding technology, it achieves stableuplink rate of 12bit/s
