HZMWD-GHZMWD-G Wireless Measurement While Drilling System applies mainly in the directional well, horizontal well, deviated well and branch well, for positioning during drilling and monitoring the drilling techniques. The acquired signals are stable and large. It is automatically decoding during the whole process of drilling. The tool configuration is simple, and it is easy to load and unload.
The detector in the Electronics Assembly measures the deviation, azimuth, tool face, etc. and converts these data to controlling signals. The Mud Pulser receives the controlling signals and controls the motions of drilling collar in the mud pipe. If the drilling collar is filled with mud or cleaned off, the mud pressure wave will be produced, showing higher or equal “1” or “0” to the mud pipe pressure. The mud pressure wave is detected by the Surface Pressure Transducer mounted in the mud pipe and acquired by the surface interface panel. The Notebook Computer completes the signal identification and decoding and gets the information, such as deviation, azimuth, tool face, etc. The drilling engineer analyzes the information so as to control the trajectories of directional well, horizontal well, deviated well and branch well. The measured data, at the same time, are sent to the Driller Display on the surface, so that the operator can monitor the drilling in real time. With a GR assembly, it can measure the geologic parameters in real time to realize the geologic directional function.
HZMWD-GThe system is composed of surface system and down tools. The surface system consists of Surface Connector BOX, Notebook Computer, Diller Display, Surface Pressure Transducer, Printer and cables. The down tool consists of Electronics Assembly, Mud Pulser, Buttery (or Down Motor), Bottom Nose and Centralizer. The down tools of HZMWD-G Wireless Measurement While Drilling System applies up-hanging mode to position the system in the Non-magnet Drill Collar. See Figure 1 and Figure 2.
