Embodiment Construction
[0016] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0017] Please refer to figure 1 , the embodiment of the present invention provides a downhole measurement information transmission system, which is used in measurement-while-drilling or non-measurement-while-drilling drilling. The downhole measurement information transmission system includes a drill string 1 as an information transmission channel, an electrode-type transmitting antenna 3 installed on the drill string 1, a downhole sensor (not shown) fixed at the first end of the drill string 1 and a connecting drill string 1 The ground detection device 5 at the second end. The downhole sensor measures downhole with the drilling of the drilling rig, and collects these measurement data at the same time, modulates the data collected by t...
