The Welleader® rotary steering drilling system could control the trajectory automatically while drill string rotating. The system could achieve fast response to drill bit position through precise guiding force vector control, with the capacity of measuring the high-precision near-bit inclination and tool face, and could achieve automatic closed-loop control of the well inclination, adapt to complicated formation condition and drilling condition and complete the drilling operations of directional well, directional well with complex 3D trajectory, extended-reach well, etc, with the ability of vertical drilling and kicking off vertically, improving drilling efficiency and borehole quality, and shortening well construction period. Drilog® Logging-While-Drilling system could provide directional measurement data and other parameters required by the monitoring of the formation evaluation, geo-steering and the state of the downhole tool and others while drilling through the real-time MWD and LWD tools. The real-time engineering parameters include:inclination, azimuth, tool face, vibration of drilling tools, drilling pressure (annular pressure, downhole pressure), wellbore diameter measurement etc. the real-time geological parameters include: natural gamma, electrical resistivity, formation density, neutron porosity, sonic wave, formation pressure, etc. Welleader® system could provide precise geo-steering drilling when making up assembly with Drilog® system of COSL.
