Description

Technical Field

[0001] This utility model relates to the field of instrument mounting structure technology, and in particular to a mounting structure for micro seismic wave instruments in oil and gas wells. Background Technology

[0002] In current methods, the main type of microseismic instrument for oil and gas wells is the geophone. The common configuration of the geophone is a detection core and a tail cone. Currently, the main configuration method for instruments in oil and gas well exploration is to use a cylindrical shell with multiple detection cores to adapt to different geological characteristics and select different frequencies. The detection cores are mostly connected in series. For example, Chinese utility model patent, publication number CN212515070U, patent title "Downhole Geophone and Infinitely Extendable Downhole Geophone String" provides a configuration method of geophones in series. However, such a configuration increases the weight of the overall shell, making the suspension burden heavy and also hindering the coupling between the tail cone and the detection target, directly affecting the data acquisition quality. Obviously, an independent suspension configuration reduces the configuration weight of the instrument shell, and an independent installation structure is a more suitable implementation method.

[0052] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. It should be noted that, for ease of description, in this application, "left side" is referred to as "first end", "right side" as "second end", "upper side" as "first end", and "lower side" as "second end" in the current view. The purpose of such description is to clearly express the technical solution and should not be construed as an improper limitation of the technical solution of this application.

[0053] This invention addresses the problem that existing microseismic instruments for oil and gas wells are excessively heavy when equipped with multiple detection cores, further increasing their weight during suspension configuration and potentially affecting data acquisition after cone-tail coupling. The invention provides an installation structure for such instruments, specifically comprising: an upper annular body 10 and a lower annular body 20 connected by a connecting column 301, as shown in the attached diagram. Figure 1 , 2 As shown, and attached Figure 4 As shown in the arrangement of the lower annular body 20 section, multiple connecting columns 301 are configured, and the upper annular body 10 and the lower annular body 20 have the same axis.

[0054] Subsequently, the main body 1 of the oil and gas well micro seismic instrument can pass through the annular space formed by the upper annular body 10 and the lower annular body 20 in sequence, and make the cone tail 2 of the main body 1 face the second direction, that is, the direction of going down into the well.

[0055] The main body 1 is radially provided with a snap-fit ​​component 100, and the upper annular body 10 is provided with a snap-fit ​​structure 110 and an axial locking component 120, so that the main body 1 can be axially fixed on the upper annular body 10; and

[0056] A radial locking member 200 is provided on the lower annular body 20 and is capable of clamping the main body 1 radially;

[0057] Thus, by fixing the main body 1 radially and axially (mainly in the axial direction of the snap-in component 100), the main body 1 is fixed on the upper annular body 10 and the lower annular body 20. That is, the main body 1 only needs to be equipped with cables at the upper end, without having to bear the weight of extra auxiliary components. By using multiple lifting rings 3 arranged in a ring array on the upper annular body 10 as auxiliary components for suspending the lower well, the configuration burden of the main body 1 is reduced, ensuring the coupling effect between the cone tail 2 and the contact target, and avoiding affecting the acquisition data.

[0058] In summary, this technical solution achieves radial and axial fixation of the main body 1 by configuring the upper annular body 10 and the lower annular body 20, reducing the configuration burden of the main body 1 involving components such as the detection core, ensuring the coupling of the cone tail 2, and thus avoiding interference with the acquired data.

[0064] In one specific embodiment, please refer to Figure 2 As shown: The upper annular body 10 is symmetrically provided with two sets of extensions 11, and a pressing pad 12 is provided on the extension 11; the contact post 13 is vertically connected to the annular surface of the upper annular body 10 and is arranged adjacent to the pressing pad 12, and the height of the pressing pad 12 is greater than the height of the contact post 13, so as to ensure accurate positioning.

[0065] In one specific embodiment, please refer to Figure 2 As shown, the contact post 13 is used to abut against the snap-in contact end 101b; the upper surface of the pressing pad 12 is used to support the lower surface of the axial pressing support 102a to ensure effective fixing pressing force.

[0066] The specific configuration of the ground pressure force is as follows: a pressing mechanism assembly is adopted, which is arranged adjacent to the pressing pad 12. The pressing mechanism assembly has a pressing component 105 and a pressing cylinder 106.

[0067] When the output end of the pressing cylinder 106 is at its minimum stroke, the pressing component 105 is pressing the upper surface of the axial pressing support 102a.

[0068] In one specific embodiment, please refer to Figure 2 , 6 As shown, the pressing mechanism assembly also includes:

[0069] The fixed seat 104 is fixedly connected to the pressing pad 12;

[0070] The pressing cylinder 106 is connected to the fixed base 104, and the output end of the pressing cylinder 106 passes through the configuration hole of the fixed base 104.

[0071] The output end of the pressing cylinder 106 moves in the first direction;

[0072] A rotating arm 107 is connected to the rotating end of the pressing component 105;

[0073] The rotating arm 107 is fixedly connected to the upper part of the fixed base 104;

[0074] Appendix Figure 2 The middle position represents the state immediately following the minimum stroke. (Attached) Figure 6 This represents the maximum stroke, i.e., the state when the pressing component 105 is open;

[0075] The action linkage 108 has one end rotatably connected to the output end of the pressing cylinder 106, and the other end rotatably connected to the arm rotation point 109 of the pressing component 105.

[0076] In one specific embodiment, please refer to Figure 4 As shown, the inner diameter of the lower annular body 20 is larger than the inner diameter of the upper annular body 10;
