 LWD wireless measurement while drilling system

       A FEWD that provides real-time measurements of main parameters such as gamma and resistivity

        It enables real-time measurement, formation evaluation, geological steering and logging while drilling services for various directional wells and horizontal wells

       Sensors provide valid geological evaluation data which is used as first-hand information by geological engineers on site to explore producible oil/gas layers.

Features of rotary steering tools:

(1)  The rotary table is capable of realizing orientation, stabilizing inclination, reducing inclination and turning the azimuth during rotary drilling process;

(2)  Auto anti-inclination control will be activated when drilling vertical sections to enhance the rate of penetration;

(3)  It is capable of purifying the wellbore, improving the quality of wellbore, smoothing the wellbore, extending horizontal section and minimizing the risk of sticking.

 

There are 4 working modes: 1) Vertical drilling mode; 2) Steering mode; 3) Stabilizing inclination mode; 4) Trip mode.
