Embodiment 1
[0071] A method of using a signal enhancement device in Embodiment 1, the steps of using include:
[0072] Coil the test fiber onto the fiber coiler 121;
[0073] Fix the fiber coiler 121 into the device body;
[0074] Connect multiple signal enhancement devices in series with optical fibers 20, and prepare to enter the well;
[0075] Put at least one hollow cable 17 into the strip groove 15 when entering the well;
[0076] Use the top wire to fasten the insert 16, and put the optical fiber 20 into the hollow cable 17, and then proceed into the well;
[0077] Connect the next device body until all device bodies have been inserted into the well.
[0078] In the above method, multiple signal enhancement devices can be placed downhole for detection, so that there are multiple enhancement points downhole, so as to obtain a better monitoring environment. Further, after multiple enhancement points are formed through the optical fiber 20 that goes into the well, the azimuth and d...
Embodiment 2
[0080] The signal enhancement device and the method for using the same according to the second embodiment, wherein the difference between the second embodiment and the first embodiment is:
[0081] like Figure 20 As shown, in the technical solution of the second embodiment, there is one optical fiber placement slot 11 located in the middle of the device body 10 , and the opening of the first sound transmission hole 14 is consistent with the placement direction of the optical fiber placement slot 11 . In the above structure, preferably, the strip grooves 15 are perpendicular to the optical fiber placement grooves 11 .
Embodiment 3
[0082] The signal enhancement device and the method for using the same according to the third embodiment, wherein the difference between the third embodiment and the first embodiment is:
[0083] like Figure 21 As shown, in the technical solution of the third embodiment, there are three optical fiber placement grooves 11, including two optical fiber placement grooves 11 arranged on both sides of the strip-shaped groove 15, and one optical fiber placement groove on the side away from the strip-shaped groove 15. In the groove 11 , the first sound transmission holes 14 are provided with a plurality of groups and are respectively consistent with the installation directions of the optical fiber placement grooves 11 . The above structure can further enhance the signal strength of the optical fiber.
