MWD(Measurement While Drilling) refers to the continuous detection of information about drill or drill While Drilling.By tracking and orientation instrument. Therefore, tracking and orientation instrument is the necessary measuring equipment of horizontal directional Drilling construction. While Drilling Logging LWD (Logging While Drilling) is the MWDS (MWD Measure While Drilling), on the basis of increasing number of sensors used for formation evaluation parameters, such as compensated dual lateral resistivity, natural gamma, bearing neutron density, sonic, compensated neutron density, etc.                                  borehole-wireless-mwd58348467988.jpg
