Embodiment Construction
[0025] The present invention will be described in detail below with reference to the accompanying drawings.
[0026] figure 1 A schematic diagram of the multi-parameter real-time measurement and transmission system for the whole well section, which is based on acoustic wave information transmission, realizes parameter measurement while drilling at multiple points along the drill string and transmits it to the surface in real time, provided for the present invention.
[0027] Such as figure 1As shown, the system consists of downhole information measurement system 1 while drilling, downhole acoustic signal emission system 2, relay information measurement system 3 while drilling, acoustic signal relay system 4, ground signal receiving system 5, ground information display and decision-making system 6 and downhole sound insulation system 7. The downhole parameter measurement system 1 while drilling collects downhole information, and the information is conditioned and transmitted ...
