Research and application of inclinometer while drilling for rotary drilling

Aiming at the status that there is no while drilling borehole track measuring equipments for impact- rotary drilling of normal drill rig, the inclinometer while drilling has been developed. The instrument consists of wellhead display controller and probe, can be used to measure track of boreholes drilled by rotary drilling with of normal underground drill rig, the attitude parameters such as dip, azimuth, tool face angle and so on. The display controller works synchronously with the probe to record the depth and time. The final results can be displayed digitally and graphically through computation and processing of raw data with data processing software.
