[0002] Seismic exploration is gradually shifting from structural oil and gas reservoir exploration to concealed oil and gas reservoir exploration, which places increasingly higher demands on the accuracy of seismic data. Exploration methods are also gradually developing towards wide-azimuth, wide-frequency, and high-density seismic exploration, which in turn places increasingly higher demands on the quantity and performance of seismic acquisition equipment.

[0023] Unless otherwise defined, all technical terms used in the embodiments of this application have the same meaning as commonly understood by one of ordinary skill in the art.

[0024] To make the technical solutions and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0025] Seismic exploration acquisition equipment is a complete instrument system used to generate, receive, and record seismic wave signals in seismic exploration work. It includes, but is not limited to, seismic sources, detectors, data acquisition stations, power supplies, and recording systems. As oil and gas exploration develops towards "high density, wide azimuth, two widths and one height" as well as nodalization and intelligence, as the core equipment in seismic exploration work, higher requirements are placed on the performance of seismic exploration acquisition equipment, such as nodal coupling.

[0026] Among them, node coupling refers to the contact quality between the seismic detector or seismic exploration and acquisition equipment and the surface / seabed, which has a significant impact on the quality of seismic data.

[0027] The existing long-tailed cone device is welded and fixed to a nodal instrument within a seismic exploration acquisition device. The nodal instrument can be understood as a dedicated node in seismic exploration operations, used as a medium for collecting seismic data. During actual exploration, the long-tailed cone welded to the nodal instrument is inserted into the ground surface to collect seismic data. However, the fixed structure of the long-tailed cone has the following drawbacks: First, the node tail vertebra is short, resulting in poor coupling in loose humus areas. This makes it easy for the node slope to frequently exceed the quality standard, and even cause it to tilt and stop collecting data. Secondly, the node has a short tail cone, which means that in gravel areas, all the thick surface gravel needs to be removed before the node instrument can be interpolated in the sand area, increasing the workload of the staff and reducing the efficiency of the node instrument's placement. Third, in desert areas, due to the short tail cone of the node and poor stability, the node instrument on the sand dune is prone to being blown off course by the wind, or even stopping data collection because the slope exceeds the preset degree.

[0028] To address the aforementioned technical deficiencies, this application provides a long tail cone device for use in seismic exploration and acquisition equipment, enabling free adjustment of the length of the long tail cone device and effectively improving the installation efficiency of the seismic exploration and acquisition equipment.

[0029] like Figure 1 As shown, the long tail cone device provided in this embodiment includes a first nut 1, a first cylinder 2, and a cone 3. Wherein, Figure 1 The schematic diagram shown is a front view of the long tailbone device.

[0030] In this embodiment, the long tail cone device is connected to the seismic exploration and acquisition equipment.

[0031] The first nut 1 is connected to the seismic exploration and acquisition equipment through a threaded coupling structure.

[0032] The first bottom surface of the first cylinder 2 is connected to the first nut 1.

[0033] Among them, the radius of any one of the base surfaces of the first cylinder 2 and the radius of the base surface of the cone 3 meet the difference threshold.

[0034] The first nut 1 is implemented as a cylinder, which is made of solid metal material.

[0035] The first cylinder 2 is implemented as a cylinder, which is made of solid metal. The height of the first cylinder 2 is a first value, and it has a first base surface and a second base surface. Figure 1 For example, the bottom surface of the upper region of the first cylinder 2 is the first bottom surface, and the bottom surface of the lower region of the first cylinder 2 is the second bottom surface.

[0036] The first cylinder 2 is connected to the first nut 1. In this embodiment, the radius of any one bottom surface of the first cylinder 2 is greater than the radius of any one bottom surface of the first nut.

[0037] Optionally, the first nut 1 is a trapezoidal cylindrical cylinder, and the first nut 1 includes a first bottom surface and a second bottom surface, the radius of the first bottom surface and the radius of the second bottom surface are different.

[0038] When the first nut 1 is implemented as a trapezoidal cylinder, the radius corresponding to the largest base of the first nut 1 is smaller than the radius of any base of the first cylinder 2.

[0039] The cone 3 is a geometric body defined by a circular surface (bottom) and a vertex (apex) that is not on the same plane as the bottom surface. The cone 3 is made of solid metal.

[0040] Optionally, the difference threshold is determined by relevant personnel based on the characteristics of the geological area to be explored.

[0041] Indicatively, the difference threshold is 0.5cm, that is, the difference between the radius of any base of the first cylinder 2 and the ground radius of the cone 3 is less than 0.5cm.

[0042] In this embodiment, any one of the bottom surfaces of the first cylinder 2 has the same radius as the bottom surface of the cone 3.

[0043] Optionally, the connection between the first cylinder 2 and the cone 3 can be a threaded connection, a snap-fit ​​connection, or a welded connection; this application does not limit this.

[0044] In this embodiment, the long tail cone device is divided into a first nut, a first cylinder, and a cone, making it a detachable device. This allows relevant personnel to replace the first cylinder of different lengths according to the actual exploration environment, further improving the burial efficiency of the long tail cone device. In addition, the tail of the long tail cone device is set as a cone, which reduces the resistance of the long tail cone device when inserted into the ground to a certain extent, further improving the burial efficiency of the long tail cone.

[0045] In some embodiments, the outer surface of the first nut 1 is configured as a first threaded structure. For example... Figure 2 And as shown in 3, Figure 2 This application shows a front view of a first nut provided in an exemplary embodiment. Figure 3 A top view of a first nut provided in an exemplary embodiment of this application is shown.

[0046] The bottom of the seismic exploration and acquisition equipment is provided with a first space, and the inner surface of the first space is provided with a second threaded structure.

[0047] The first nut 1 and the seismic exploration and acquisition equipment are coupled by rotating and screwing together the first thread structure and the second thread structure.

[0048] It is understandable that the first nut 1 is equivalent to a screw, and the seismic exploration and acquisition equipment is the nut. The first nut 1 and the seismic exploration and acquisition equipment are physically connected through the engagement of their threads.

[0049] In some embodiments, a second space is provided within the first bottom surface of the first cylinder, and the inner surface of the second space is implemented as a third thread structure.

[0050] The first bottom surface of the first cylinder 2 and the first nut 1 are coupled by engaging the third thread structure and the second thread structure through rotation and screwing.

[0051] It is understandable that the first nut 1 is equivalent to a screw, the first cylinder 2 is a nut, and the first nut 1 and the first cylinder 2 are physically connected by the engagement of their threads.

[0052] In this embodiment, the first nut is used to connect the long tail cone device and the seismic exploration and acquisition equipment to fix the long tail cone device to the seismic exploration and acquisition equipment as a whole, so as to facilitate the synchronous vibration of the core of the long tail cone device and the seismic exploration and acquisition equipment during seismic exploration operations.

[0053] In some embodiments, a slot 20 is provided at a preset position on the outer surface of the first cylinder 2.

[0054] The slot 20 is implemented as part of the first cylinder 2 for assembling or disassembling the long tail cone device from the seismic exploration and acquisition equipment, and for securing the long tail cone device to the seismic exploration and acquisition equipment.

[0055] In this embodiment, the first cylinder 2 is made of solid metal material, and the slot 20 is either a cut area of ​​the first cylinder 2 or a hollow area of ​​the first cylinder 2. For specific implementation details, please refer to the following description.

[0056] In some embodiments, the card slot 20 includes a first card slot 200 and a second card slot 201, the first card slot 200 and the second card slot 201 being symmetrical about the central axis of the first cylinder 2.

[0057] It can be understood that the slot 20 is equivalent to cutting a specified volume area off the surface of the first cylinder 2, making the first cylinder 2 an irregular cylinder, such as... Figure 4 as well as Figure 5 As shown, Figure 4 This application shows a front view of a card slot provided in an exemplary embodiment. Figure 5 A side view of a card slot provided in an exemplary embodiment of this application is shown. Figure 4 This is a front view. The front of the first cylinder 2 shows a first card slot 200, and the back of the first card slot 200 shows a second card slot 201. Figure 4 (The front view shown is not visible). Figure 5 In the side view shown, the first cylinder 2 contains a first slot 200 and a second slot 201.

[0058] In some embodiments, the space occupied by the first slot 200 on the surface of the first cylinder 2 is the same as the space occupied by the second slot 201 on the surface of the first cylinder 2.

[0059] The space occupied by the first slot 200 on the surface of the first cylinder 2 is different from the space occupied by the second slot 201 on the surface of the first cylinder 2.

[0060] The area of ​​the first card slot 200 overlaps with the area of ​​the second card slot 201.

[0061] In some embodiments, the slot 20 is implemented as a hollow region that extends laterally through the first cylinder 2.

[0062] It is understandable that, taking the front view as an example, the width of the hollow area is less than the diameter of the first cylinder 2, and taking the side view as an example, the length of the hollow area is equal to the diameter of the first cylinder 2.

[0063] In some embodiments, the long tail cone device further includes a second cylinder 4.

[0064] The first bottom surface of the second cylinder 4 is connected to the second bottom surface of the first cylinder 2.

[0065] The second bottom surface of the second cylinder 4 is connected to the bottom surface of the cone 3.

[0067] In some embodiments, the long tail cone device further includes a second nut 5.

[0068] The first bottom surface of the second cylinder 4 is connected to the second bottom surface of the first cylinder 2 by the second nut 5.

[0069] Optionally, a third space is provided on the first bottom side of the second cylinder 4, and a fourth thread structure is provided on the inner surface of the third space.

[0070] The coupling connection between the first bottom surface of the second cylinder 2 and the second bottom surface of the first cylinder 2 is achieved by engaging the fourth and fifth threaded structures through rotation and screwing.

[0071] In an optional embodiment, a slot is provided at a preset position on the outer surface of the second cylinder 4. The way the slot is set in the second cylinder 4 is the same as the way the slot 20 is set in the first cylinder 2, which will not be described in detail here.

[0072] In some embodiments, the long tail cone device includes a second cylinder 4, a second nut 5, a third cylinder 6, and a third nut 7.

[0073] The first bottom surface of the second cylinder 2 is connected to the second bottom surface of the first cylinder 2 by the second nut 5.

[0074] The second bottom surface of the second cylinder 2 is connected to the first bottom surface of the third cylinder 6 by the third nut 7.

[0075] The second bottom surface of the third cylinder 6 is connected to the bottom surface of the cone 3. Schematic, the second bottom surface of the third cylinder 6 and the cone 3 are physically connected by a threaded structure or a snap-fit ​​structure.

[0076] Among them, the heights of the first cylinder 2, the second cylinder 4, and the third cylinder 6 are the same or different, and the radii of any one base of the first cylinder 2, the second cylinder 4, and the third cylinder 6 are the same or different.

[0077] The first bottom surface of the second cylinder 2 has a space that matches the surface area of ​​the second nut 5, and the second bottom surface of the first cylinder 3 has a space that matches the surface area of ​​the second nut 5. The outer surfaces of both spaces are threaded, and the coupling connection between the first cylinder 2 and the second cylinder 2 is achieved through the engagement of the threaded structures.

[0078] In another alternative embodiment, the first nut 1 and the first bottom surface of the first cylinder 2 are fixedly connected, such as by welding.

[0079] In another optional embodiment, the second nut 5 and the first bottom surface of the second cylinder 4 are fixedly connected, such as by welding.

[0080] The second bottom surface of the second cylinder 2 exists in a space that matches the surface area of ​​the third nut 7, and the first bottom surface of the third cylinder 6 exists in a space that matches the surface area of ​​the third nut 7. The outer surfaces of both spaces are threaded, and the coupling connection between the second cylinder 2 and the third cylinder 6 is achieved through the engagement of the threaded structures.

[0081] In this embodiment, the long tail cone device includes a first nut 1, a first cylinder 2, a second cylinder 4, a second nut 5, a third cylinder 6, a third nut 7, a fourth cylinder 8, a fourth nut 9, and a cone 3. These components are connected sequentially from top to bottom, as follows: Figure 6 as well as Figure 7 , Figure 6 A front view of a long tailbone device provided in another exemplary embodiment of this application is shown. Figure 7 A side view of a long tailbone device provided in another exemplary embodiment of this application is shown. Figure 6 as well as Figure 7 In the middle, from top to bottom, are connected the seismic exploration and acquisition equipment, the first nut 1, the first cylinder 2, the second nut 5, the second cylinder 4, the third nut 7, the third cylinder 6, the fourth nut 9, the fourth cylinder 8, and the cone 3. Figure 6 as well as Figure 7 In the original text, the length of the first cylinder 2 is greater than the length of the second cylinder 4, which is greater than the length of the third cylinder 6, which is greater than the length of the fourth cylinder 8. However, in actual exploration, this application does not impose any restrictions on the lengths of the first cylinder 2, the second cylinder 4, the third cylinder 6, and the fourth cylinder 8. The lengths of the three cylinders may be equal or unequal.

[0082] exist Figure 6 as well as Figure 7 In the first cylinder 2, a slot 20 is included; in the second cylinder 4, a slot is included; in the third cylinder 6, a slot is included. The way the slot is set in the second cylinder 4 is the same as the way the slot 20 is set in the first cylinder 2; the way the slot is set in the third cylinder 6 is the same as the way the slot 20 is set in the first cylinder 2; and the way the slot is set in the fourth cylinder 8 is the same as the way the slot 20 is set in the first cylinder 2.

[0083] In this embodiment, taking a humus-rich surface construction project as an example, the project involves acquiring seismic exploration acquisition equipment nodes at a 20m receiver distance on the loose humus surface and burying them during construction. Given that the humus thickness in the work area is mainly concentrated between 10 and 20 centimeters, the long tail cone is designed as a 25-centimeter-long structure connecting a cylinder and a cone. This long tail cone device also includes a nut.

[0084] The long tail cone device is fixed to the node. During construction, the long tail cone device is buried in the loose humus surface. The bottom of the long tail cone device is inserted 30 cm into the loose bottom surface. If the humus is thick, a pit of appropriate depth is dug at the node location first, and then the node is also buried in the humus. In order to ensure the stability of the node in receiving satellite signals, the depth of the top surface of the node from the ground is generally less than 5 cm, and the bottom of the long tail cone device is inserted 45 cm into the loose ground surface.

[0085] The long-tailed cone device provided in this application is suitable for seismic exploration data acquisition in special geological conditions such as loose humus surfaces, gravel areas, and sand dune areas. By installing the long-tailed cone device on a dedicated geophysical node, the contact area and depth between the node and the surface are increased, significantly improving the coupling performance and stability between the node and the surface in loose humus surface areas, preventing the node from toppling and stopping data acquisition due to loose surface; while improving the coupling and stability of the node in gravel areas, it significantly reduces the node installation time and labor intensity; and it significantly reduces the probability of the node ceasing operation due to large node slope caused by wind blowing sand in sand dune areas. This improves the quality of seismic exploration data.

[0086] It should be noted that the specific figures listed in the above embodiments are merely exemplary distances, designed based on actual working conditions. Distance and length limitations involved in other construction conditions fall within the protection scope of this application.
