Embodiment 1
[0019] Embodiment one: see figure 1 , figure 2 , the response inspection device of the electromagnetic wave resistivity logging tool while drilling according to the present invention includes a disc-type insulating support body, and the diameter of the center hole of the disc-type insulating support body matches the diameter of the electromagnetic wave resistivity logging tool while drilling. At least one open-circuit circular metal ring 2 is provided on the support surface of the disk-type insulating support body, and the circular metal ring 2 is gradually distributed outward around the center of the support disk surface of the disk-type insulation support body. The notch end of 2 leads to a quick connector 6, and n resistance-capacitance modules 7 are provided to match the quick connector 6, and n is a natural number.
[0020] 1 is a supporting plate among the figure.
Embodiment 2
[0021] Embodiment two: see Figure 1 ~ Figure 3 The difference between the response inspection device of the electromagnetic wave resistivity logging tool while drilling in this embodiment and the first embodiment is that the structure of the resistance-capacitance module 7 is further described, and the resistance-capacitance module includes m parallel capacitors and p parallel capacitors The resistance-capacitance circuit formed after the resistors are connected in series and the connector matched with the quick joint 6 drawn from the notch end of the circular metal ring 2, the resistance-capacity circuit is connected in series between the two quick joints of the connector. m and p are natural numbers. The present invention is provided with multiple resistance-capacitance modules, image 3 An implementation manner of a resistance-capacitance module is provided.
Embodiment 3
[0022] Embodiment three: see figure 1 , figure 2 , the response inspection device of the electromagnetic wave resistivity logging tool while drilling in this embodiment, the disc-type insulating support body includes a support disc 1 and a rotating drum 8, and the rotating drum 8 is matched and nested on the supporting disc of the disc-type insulating support body 1, the plane where the support disc 1 is located is perpendicular to the center line of the drum 8, and the aperture of the drum 8 matches the diameter of the EWD logging tool.
