DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1 As shown, an application device suitable for a seismic fluid observation wellhead comprises: a hoop 1 mounted on the top of the wellhead; a line-releasing mechanism 2 detachably connected to the periphery of the top of the hoop 1; an inner support frame 3 detachably connected to the middle of the hoop 1; and a line-dividing mechanism 4 slidably connected to the middle of the inner support frame 3, wherein the line-dividing mechanism 4 moves up and down in the observation well.

[0027] like Figure 2As shown, an upper cover ring 11 is provided on the top of the ferrule 1, the middle part of the upper cover ring 11 is a circular through hole, below the circular through hole is an observation well, the inner diameter of the circular through hole is smaller than the inner diameter of the wellhead, the upper cover ring 11 is erected on the top surface of the wellhead, a groove 111 is provided on the inner side of the upper cover ring 11, an inner support frame 3 is detachably connected to the groove 111, the inner support frame 3 is a cross-shaped frame, and after the inner support frame 3 is placed in the groove 111, it can prevent the ferrule 1 from shrinking and deforming inward, thereby increasing the stability of the ferrule 1.

[0028] The lower part of the hoop 1 is located on the side wall of the observation well, and the inner diameter of the lower part of the hoop 1 is larger than the outer diameter of the observation well. Therefore, the hoop 1 can be suitable for observation wells of different sizes smaller than the inner diameter of the hoop 1. A plurality of first positioning holes 12 are opened on the lower side wall of the hoop 1. The first positioning holes 12 are distributed in a circular array on the lower side wall of the hoop 1. The first positioning holes 12 penetrate the side wall of the hoop 1. An internal thread is provided in the first positioning hole 12. A positioning bolt 13 is screwed in the first positioning hole 12. The positioning bolt 13 is pressed against the side wall of the observation well by twisting the positioning bolt 13. After pressing, the hoop 1 is positioned so that the hoop 1 is stably connected to the wellhead.

[0029] like Figure 3 As shown, the line-releasing mechanism 2 includes a base 21, a support shaft 22, a rotating tube 23, an adjusting rod 24 and a limiting tube 25. The base 21 is detachably connected to the upper cover ring 11, the support shaft 22 is fixed to the top of the base 21, the rotating tube 23 is rotatably connected to the upper part of the support shaft 22, the adjusting rod 24 is slidably connected to the rotating tube 23, and the limiting tube 25 is fixed to the front end of the adjusting rod 24.

[0030] A plurality of second positioning holes 112 are provided on the upper cover ring 11, and threads are provided inside the second positioning holes 112. Three anti-roll columns 211 are provided at the bottom of the base 21. The anti-roll columns 211 are cylinders without threads, but the anti-roll columns 211 can be inserted into the second positioning holes 112. After being inserted into the second positioning holes 112, the position of the base 21 is restricted. When the base 21 tilts forward or backward, the anti-roll column 211 can effectively prevent overturning. A bolt 212 is also provided on the base 21. The bolt 212 passes through the base 21, and the bottom of the bolt 212 can be screwed into the second positioning hole 112. The bolt 212 further fixes the position of the base 21. When disassembling the base 21, only one bolt 212 needs to be removed to remove the entire base 21.

[0031] The support shaft 22 is cylindrical as a whole, and a shaft groove 223 is provided on the top of the support shaft 22. A rotating shaft 221 passes through the side wall of the support shaft 22. The other end of the rotating shaft 221 passes through the side wall of the shaft groove 223 and is fixedly connected to the side wall of the rotating tube 23. The rotating shaft 221 realizes the relative rotation between the rotating tube 23 and the shaft groove 223. The locking nut 222 can be screwed into the outside of the rotating shaft 221. When the locking nut 222 is tightened, the locking nut 222 squeezes the support shaft 22, so that the friction between the support shaft 22 and the rotating tube 23 increases, and the rotation of the rotating tube 23 is limited. By rotating the rotating tube 23, the front end of the rotating tube 23 is at different heights, which is convenient for monitoring personnel to distinguish different monitoring equipment according to height, eliminating the need to find the monitoring recorder through the line.

[0032] The length of the adjusting rod 24 is greater than that of the rotating tube 23. The adjusting rod 24 slides back and forth in the rotating tube 23. A pressing bolt 242 penetrates the side wall of the rotating tube 23. The pressing bolt 242 contacts the side wall of the adjusting rod 24. When the pressing bolt 242 rotates inward, the pressing bolt 242 squeezes the side wall of the adjusting rod 24 to limit the sliding of the adjusting rod 24.

[0033] The limiting tube 25 is perpendicular to the adjusting rod 24 , and the equipment line 5 passes through the limiting tube 25 . The limiting tube 25 limits the shaking of the upper part of the equipment line 5 , so as to prevent the equipment line 5 from being entangled at the upper part.

[0034] A scale line 241 is provided at the rear end of the adjusting rod 24. The scale display where the scale line 241 contacts the rear end of the rotating tube 23 is the distance between the front end of the adjusting rod 24 and the front end of the rotating tube 23. By adjusting the position of the adjusting rod 24, the equipment line 5 can be at different lengths from the inside of the observation well, reducing the possibility of collision between different equipment lines 5.

[0035] like Figure 4 As shown, the wire-dividing mechanism 4 includes a wire-dividing claw 41, a base rod 42, an extension rod 43 and a positioning ring 44. The wire-dividing claw 41 is arranged at the bottom of the base rod 42. The top of the base rod 42 passes through the middle of the inner support frame 3. The base rod 42 can slide up and down relative to the support frame. The positioning ring 44 is screwed to the outer wall of the top of the base rod 42. The outer diameter of the positioning ring 44 is larger than the outer diameter of the base rod 42. The positioning ring 44 cannot pass through the inner support frame 3. The positioning ring 44 can limit the downward movement of the base rod 42 and the wire-dividing claw 41. The extension rod 43 is screwed to the inner wall of the top of the base rod 42. The extension rod 43 can also be screwed to the positioning ring 44. The extension rod 43 can also pass through the inner support frame 3. When the bottom of the wire-dividing claw 41 needs to move downward, the positioning ring 44 can be screwed into the extension rod 43 to fix the position of the wire-dividing claw 41.

[0036] The dividing claw 41 is a plurality of rods in a circular array at the bottom of the base rod 42. The dividing claw 41 divides the observation well into a plurality of observation areas. Each observation area passes through an equipment line 5. The dividing claw 41 is placed under the equipment line 5. The dividing claw 41 restricts each equipment line 5 to a different observation area. The dividing claw 41 prevents the bottom of the equipment line 5 from being entangled and overlapped when fluid flows.

[0037] The limit tube 25 limits the shaking of the equipment line 5 above, and the line separation claw 41 limits the shaking of the equipment line 5 when it is lowered. The two cooperate to reduce the entanglement of the equipment line 5.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
