Directional drilling measuring instrument is important for directional drilling system, it is designed for the hole trajectory control. With the development of directional drilling technology, high quality directional drilling system is based on advanced measuring instruments.
According to the measuring principle, directional drilling instruments can be divided into magnetic measuring instrument and gyro measuring instrument. MWD instrument is a kind of magnetic measuring instrument. It includes two parts: subsurface instrument and surface instrument. Subsurface instrument consist of pulser, inclinometer, cable head, lengthening bar, weight bar, and compressive cylinder, etc. Surface instrument consist of industrial personal computer (IPC), displayer, and cable winch, etc. As we all know, MWD/LWD directional module is one of the key parts of MWD instrument, It is designed to measuring angles of inclination, azimuth, and tool face, and also can measure the temperature, and acceleration in downhole applications.
Qingdao ZITN designs, develop, and manufacture directional modules for MWD, LWD and wireline logging tools. With advanced MCM technology, our directional module can work in harsh environment for a long term. It has advantages of high reliability and high temperature resistance, etc. For more details please feel free to contact us.
