Description

Technical Field

[0001] This utility model relates to the field of wellbore cable laying technology, specifically to a wellbore equipment positioning and laying device. Background Technology

[0002] During the construction of the well shaft equipment, eight survey lines need to be laid out as positioning references for the installation of the steel components of the well shaft, such as... Figure 1 and Figure 2 As shown. In the past, after the wellbore equipment was measured and positioned, eight special manual line-laying carts 3' were manufactured and welded to the sealing plate 2 at the top of the wellbore 1. Two people worked together to operate one line-laying cart, and sixteen people were required to manually crank the wellbore measuring line on the sealing plate 2 to lower and retrieve it.

[0003] Using a dedicated line-laying vehicle for manual operation of wellbore line laying not only easily leads to asynchronous line laying speed and line breakage, but also easily causes accidents such as injury to the line-laying disc rocker arm due to improper operation. It involves a large number of personnel, high labor intensity, and high safety risks.

[0004] 1. High manpower input: Because multiple survey lines need to be laid inside the well, traditional construction methods require a large amount of manpower.

[0005] 2. Low efficiency: The arrangement of hand-cranked measuring discs is inefficient and requires a lot of time and manpower.

[0006] 3. Difficulty in guaranteeing accuracy, easily leading to wellbore line breakage: Due to the instability of manual operation, the accuracy of laying out the survey lines is difficult to guarantee.

[0007] 4. High safety risks during line laying: Each measuring reel requires two people to work together to manually lower and retrieve the measuring line. Uncoordinated operation can easily lead to slippage and injuries.

[0008] 5. The eight wire feeding reels are positioned at fixed locations on the sealing reel, occupying the safe operating space of the sealing reel. When feeding or removing materials, collisions with the wire feeding reels are likely to occur, causing safety accidents and greatly affecting the construction of the well equipment. Utility Model Content

[0009] The technical problem to be solved by this utility model is: how to solve the problems of high manpower input and low efficiency in the current wellbore laying.

[0010] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0011] A wellbore equipment positioning and laying device is provided, which includes a wellbore frame installed above the wellbore and a plurality of measuring line guide wheels installed on the wellbore frame. Each of the plurality of measuring line guide wheels is provided with a corresponding electric laying machine. A wire hole is opened on the wellbore frame facing the inside of the wellbore. The measuring line guide wheel is located on one side of the wire hole. The measuring line wound on the electric laying machine passes through the measuring line guide wheel and enters the wellbore through the wire hole.

[0012] This application uses an electric wire-laying machine to drive a steel wire reel as a wire-laying device for lowering and retrieving the steel wire in the wellbore. Several electric wire-laying machines are equipped with a centralized control console, requiring only one person to centrally control them, achieving centralized electric operation. This allows for both simultaneous lowering and retrieving of the survey line and individual operation. The machines are positioned at the edge of the wellhead sealing plate, solving the problem of traditional manual wire-laying vehicles occupying the operating space of the sealing plate, and addressing the issues of high personnel input, high labor intensity, and high safety risks.

[0013] As a further embodiment of this utility model: the well frame includes a sealing plate and a steel plate installed above the well shaft, the sealing plate includes several I-beams arranged horizontally and vertically, and the steel plate is installed above the sealing plate.

[0014] As a further embodiment of this utility model: the measuring line guide wheel is installed above the steel plate, and a protective steel capable of penetrating the measuring line is provided above the steel plate and on one side of the measuring line guide wheel.

[0015] As a further embodiment of this utility model: several of the electric wire-laying machines are installed on the outside of the well shaft.

[0016] As a further embodiment of this utility model: the measuring guide wheel and the electric wire feeding machine are installed on the I-beam inside the sealing plate.

[0017] As a further embodiment of this utility model, it also includes a centralized operating platform electrically connected to several electric wire feeding machines.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0033] Example 1

[0034] Reference Figure 3 and Figure 4A wellbore equipment positioning and laying device includes a protective steel 5, an electric laying machine 6, a measuring guide wheel 7, a measuring line 8, and a centralized operating platform 9. A sealing plate 2 is installed on the top of the wellbore 1, wherein the bottom of the sealing plate 2 is fixed to the top of the wellbore 1 by a support 4, and a steel plate 3 is installed on the top of the sealing plate 2. The protective steel 5 and the measuring guide wheel 7 are both set on the top of the steel plate 3.

[0035] Reference Figure 3 and Figure 4 The sealing plate 2 includes several I-beam structures arranged laterally and longitudinally, from Figure 4 It can be seen that several I-beams form a mesh structure arranged above the shaft 1.

[0036] Reference Figure 3 and Figure 4 Several holes are made on the steel plate 3 directly above the corresponding measuring point inside the well shaft, i.e. towards the measuring point, for the measuring line 8 to pass through. The measuring line 8 passes through the holes and enters the well shaft 1.

[0037] Reference Figure 3 The test line guide wheel 7 is installed on the top of the steel plate 3 and located on one side of the line hole. A protective steel 5 for protecting the test line 8 is also provided on the top of the steel plate 3 and on one side of the test line guide wheel 7. It should be noted that the number of protective steel 5, electric wire feeding machine 6, test line guide wheel 7 and line hole is the same.

[0038] Reference Figure 3 Several electric wire-laying machines 6 are installed outside the well shaft. The measuring wire 8 wound on the electric wire-laying machine 6 passes through the wire hole of the measuring wire guide wheel 7 and enters the well shaft 1.

[0039] It should be noted that several electric wire-laying machines 6 are electrically connected to a centralized operating platform 9. The centralized operating platform 9 can be located on one side of the wellbore 1. Through the centralized operating platform 9, several electric wire-laying machines 6 can be centrally processed, requiring only one person to centrally control them. This enables centralized electric operation, allowing for both simultaneous lowering and retrieval of the survey line, as well as individual operation. The platform is positioned at the edge of the wellhead sealing plate 2, resolving the issue of the wire-laying vehicle occupying the operating space of the sealing plate.

[0040] The specific operating principle of this application is as follows: First, the top of the well shaft 1 is installed to the sealing plate 2 via the support frame 4. The sealing plate 2 consists of several I-beams arranged horizontally and vertically. After all the I-beams are installed, the steel plate 3 is laid. Then, the measuring guide wheel 7 and the protective steel 5 are installed on the steel plate 3 on one side of the wire hole. Several electric wire feeding machines 6 are installed on the outside of the sealing plate 2. In use, the control console 9 can centrally control the electric wire feeding machines 6. The electric wire feeding machines 6 drive the steel wire drum as a wire feeding device to lower and retrieve the steel wire in the well shaft. This design allows the measuring line 8 to pass through the protective steel 5 and the measuring line guide wheel 7, enter the wire hole of the steel plate 3, and then be guided into the well shaft 1. The installation of the measuring line 8 can then be achieved. The number of measuring lines 8 depends on the actual site conditions; this application specifies eight groups, but this is only one implementation method and should not be construed as a limitation of the application. Several electric wire-laying machines are installed, requiring only one person to centrally control them from the operating platform, enabling centralized electric operation. This allows for both simultaneous lowering and retrieval of the measuring line, as well as individual operation. The machines are positioned at the edge of the wellhead sealing plate, solving the problem of traditional manual wire-laying vehicles occupying the operating space of the sealing plate.

[0041] Example 2

[0042] Reference Figure 5 Unlike Embodiment 1, Embodiment 2 installs the electric wire feeding machine 6 and the wire measuring guide wheel 7 in the middle of the I-beam of the sealing plate 2, or only installs the wire measuring guide wheel 7 in the middle of the I-beam of the sealing plate 2, with the electric wire feeding machine 6 located on the outside of the sealing plate 2. This arrangement can expand the operating space on the top of the steel plate 3 compared to Embodiment 1.

[0043] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
