Description

Technical Field

[0001] This invention relates to the field of antenna loading technology, and more particularly to a method for horizontal loading of an antenna inside a well. Background Technology

[0002] The current method for loading antennas into wells is to use a crane in the technical workshop to lift the antennas vertically and load them into the well shaft.

[0003] Existing installation methods have problems such as high requirements for factory building height, long hoisting time, inconvenience for personnel to operate inside the well, and safety risks.

[0004] Therefore, a loading device is needed that can load the antenna into the well in a horizontal position without raising it. The loading device must also be able to load and unload the antenna horizontally within the technical facility. Summary of the Invention

[0005] Based on the above analysis, the present invention aims to provide a horizontal loading method for antennas inside wells, in order to solve the problems of existing methods that require the well to be verticalized before the antenna can be hoisted, which is complicated and occupies a lot of space.

[0006] The objective of this invention is mainly achieved through the following technical solutions:

[0007] A method for horizontally loading an antenna into a well, using an antenna horizontal loading device, includes the following steps:

[0008] Step S1: Place the wellbore and the semi-circular groove horizontally; and place the antenna in the semi-circular groove;

[0009] Step S2: Align the ends of the wellbore and the semi-circular groove;

[0010] Step S3: Drive the loading device to move it axially along the semi-circular groove and push the antenna into the wellbore.

[0011] Furthermore, in step S1, the wellbore is supported by the front support and the well support vehicle.

[0012] Furthermore, in step S1, the semi-circular groove is supported by a groove support vehicle.

[0013] Furthermore, in step S2, the wellbore and the semi-circular groove are aligned horizontally by adjusting the lateral movement device.

[0014] Furthermore, in step S2, the wellbore is rotated along its own axis by a rolling device so that the port of the wellbore is aligned with the port of the semi-circular groove.

[0015] Furthermore, in step S2, the height of the well shaft is adjusted by adjusting the lifting device so that the well shaft is aligned vertically with the semi-circular groove.

[0016] A horizontal loading device for an in-well antenna is provided for realizing a horizontal loading method for an in-well antenna. The horizontal loading device for an in-well antenna includes a loading mechanism, which includes a loading frame, a gear, and a motor. The loading frame is mounted above a semi-circular groove. A rack is provided on the upper end face of the semi-circular groove. The gear is rotatably mounted on the loading frame and meshes with the rack. The motor can drive the gear to rotate.

[0017] Furthermore, when the motor drives the gear to rotate, the gear rolls on the rack, which in turn drives the filling frame to move linearly along the guide rail of the semi-circular groove.

[0018] Furthermore, when the loading frame moves linearly along the guide rail of the semi-circular groove, the antenna is moved by the U-shaped frame on the loading frame, and the antenna is loaded into the well barrel from the semi-circular groove.

[0019] Furthermore, the front support, cylinder support vehicle, and trench support vehicle are all mounted on the base plate; before aligning the wellbore and the semi-circular trench, the base plate is first leveled.

[0020] Furthermore, both the front support and the barrel support vehicle are equipped with lifting and rolling devices; the lifting device can adjust the height of the well barrel; the rolling device can adjust the deflection angle of the well barrel along its own axis; the slot support vehicle is equipped with a lateral movement device, which can adjust the horizontal position of the semi-circular slot.

[0021] Furthermore, the lifting device is either an electrically driven lifting device or a manually driven lifting device; the electrically driven lifting device is an electric hydraulic cylinder or a pneumatic cylinder; the manually driven lifting device includes: an adjusting rod, a worm gear mechanism, and a lead screw; when the adjusting rod rotates, it can drive the lead screw to move up and down through the worm gear mechanism.

[0022] Furthermore, the rolling device includes: rollers and a locking mechanism; the rollers are rotatably mounted at the bottom of the support groove; there are multiple rollers arranged in an arc shape; the wellbore bracket is placed on the multiple rollers arranged in an arc shape; the locking mechanism is set on the support groove and can limit the relative displacement between the wellbore bracket and the support groove.

[0023] Furthermore, by pushing the wellbore bracket to roll relative to the rollers, the wellbore bracket is deflected, which in turn causes the wellbore above the wellbore bracket to deflect along its own axis.

[0024] Furthermore, the lateral movement device includes a slide rail and a chute; a slide rail is provided on the base of the chute support vehicle; a chute is slidably installed above the slide rail, and a circular chute bracket is fixedly installed above the chute; the semi-circular chute is supported by the circular chute bracket; pushing the circular chute bracket causes the chute to slide along the slide rail, thereby driving the semi-circular chute to move horizontally.

[0025] Furthermore, the arc-shaped arrangement of the rollers and the arc-shaped structure of the wellbore bracket are concentrically set with the arc-shaped bottom surface of the semi-circular groove. The axes of the arc-arranged rollers, wellbore bracket, and semi-circular groove coincide.

[0026] The technical solution of this invention can achieve at least one of the following effects:

[0027] 1. The horizontal loading device of the present invention enables the antenna and the well shaft to be quickly and conveniently connected and loaded when both the antenna and the well shaft are in a horizontal state, allowing the antenna to be loaded into or unloaded from the well shaft without the need for personnel to enter the well shaft.

[0028] This invention enables rapid docking and alignment of the antenna and wellbore in a horizontal state by adjusting the base frame, semi-circular groove, front support, barrel support vehicle, and support vehicle. Rapid horizontal loading or unloading is achieved through a motor, gears, racks, locking mechanism, and control system.

[0029] The horizontal loading device of the present invention enables the horizontal loading and unloading of antennas in the technical plant, solving the problems of high requirements for the lifting height of the plant, long lifting time, inconvenience for personnel to operate in the well, and high safety risks in hoisting and loading.

[0030] In this invention, the above-described technical solutions can be combined with each other to achieve more preferred combinations. Other features and advantages of this invention will be set forth in the following description, and some advantages may become apparent from the description or be learned by practicing the invention. The objects and other advantages of this invention can be realized and obtained from what is particularly pointed out in the description and drawings. Attached Figure Description

[0057] The well shaft 10 is rotated along its own axis by a rolling device, so that the port of the well shaft 10 is aligned with the port of the semi-circular groove 6.

[0058] Furthermore, the lifting device is either an electrically driven lifting device or a manually driven lifting device; the electrically driven lifting device is an electric hydraulic cylinder or a pneumatic cylinder; the manually driven lifting device includes: an adjusting rod 303, a worm gear mechanism 302, and a lead screw 304; when the adjusting rod 303 rotates, it can drive the lead screw 304 to move up and down through the worm gear mechanism 302.

[0060] By pushing the wellbore bracket 306 to roll relative to the roller 307, the wellbore bracket 306 is deflected, which in turn drives the wellbore 10 above the wellbore bracket 306 to deflect along its own axis.

[0061] Furthermore, the transverse movement device 504 includes a slide rail and a chute; a slide rail is provided on the tank base 501 of the chute support vehicle 5; a chute is slidably installed above the slide rail, and a circular chute bracket 503 is fixedly installed above the chute; the semi-circular chute 6 is supported by the circular chute bracket 503; pushing the circular chute bracket 503 causes the chute to slide along the slide rail, thereby driving the semi-circular chute 6 to move horizontally.

[0064] Furthermore, the front support 3, the cylinder support vehicle 4, and the groove support vehicle 5 are all mounted on the base plate 2; before aligning the well cylinder 10 and the semi-circular groove 6, the base plate 2 is leveled first.

[0065] Example 2

[0066] A specific embodiment of the present invention discloses a horizontal loading device for an in-well antenna, used to implement the horizontal loading method for an in-well antenna in Embodiment 1.

[0067] The in-well antenna horizontal loading device includes: a front support 3, a cylindrical support vehicle 4, a slotted support vehicle 5, a semi-circular slot 6, and a loading mechanism 7; wherein, the front support 3 and the cylindrical support vehicle 4 are used to support the wellbore 10, the slotted support vehicle 5 is used to support the semi-circular slot 6, the antenna 11 is placed in the semi-circular slot 6, and the loading mechanism 7 can drive the antenna 11 to slide along the semi-circular slot 6; furthermore, the front support 3 and the cylindrical support vehicle 4 are each equipped with a lifting device and a rolling device, the lifting device can adjust the height of the wellbore 10, and the rolling device can adjust the deflection angle of the wellbore 10 along its own axis; furthermore, the slotted support vehicle 5 is equipped with a lateral movement device, which can adjust the semi-circular slot 6 to move laterally. The horizontal antenna loading device in the well of the present invention can move the semi-circular groove 6 and the well barrel 10 towards each other by pushing the groove support vehicle. Then, the vertical height and deflection angle of the well barrel 10 can be adjusted by adjusting the lifting device and the rolling device. The horizontal position of the semi-circular groove 6 can be adjusted by adjusting the lateral movement device, so that the ports of the well barrel 10 and the semi-circular groove 6 are aligned. After the well barrel 10 and the semi-circular groove 6 are aligned, the antenna 11 is pushed along the semi-circular groove 6 by the loading mechanism 7, so that the antenna 11 can be loaded into the well barrel 10.

[0068] In one specific embodiment of the present invention, the front support 3 includes: a support base 301, a lifting device, a rolling device, a support groove 305, and a well shaft bracket 306; the support groove 305 is installed on the support base 301 via the lifting device; the well shaft bracket 306 is installed in the support groove 305 via the rolling device, and the well shaft bracket 306 is used to support the well shaft 10.

[0069] Furthermore, the lifting device is an electrically driven lifting device or a manually driven lifting device; the electrically driven lifting device is an electric hydraulic cylinder or a pneumatic cylinder; the manually driven lifting device includes: an adjusting rod 303, a worm gear mechanism 302, and a lead screw 304; when the adjusting rod 303 rotates, it can drive the lead screw 304 to move up and down through the worm gear mechanism 302.

[0070] Furthermore, the rolling device includes: rollers 307 and locking mechanism 308; the rollers 307 are rotatably mounted on the bottom of the support groove 305; there are multiple rollers 307 arranged in an arc shape; the well shaft bracket 306 is placed on the multiple rollers 307 arranged in an arc shape; the locking mechanism 308 is disposed on the support groove 305 and can limit the relative displacement between the well shaft bracket 306 and the support groove 305.

[0071] like Figure 2 , Figure 3 As shown, the front support 3 consists of a lifting device and a rolling device, and is installed at the front end of the base frame. The function of the front support 3 is to bear the weight of the well shaft 10 and the antenna 11, and it has the functions of adjusting the vertical direction and the rolling direction. There are two sets of lifting devices, and the support slot 305 adopts two-point support, supported by two sets of lifting devices. Specifically, the lifting mechanism is a screw jack, which can realize the lifting movement. The lifting movement of the lifting mechanism is realized by operating the adjusting rod 303 of the screw jack. The adjusting rod 303 is connected to the symmetrical lifting mechanism through a coupling to ensure that the left and right screw jacks move synchronously. When lifting, the adjusting rod 303 is rocked to adjust the extension length of the screw 304, thereby driving the support slot 305 to move up and down, and finally realizing the height adjustment of the well shaft 10.

[0072] The rolling device employs a roller support mechanism, including a support groove 305, rollers 307, and a locking mechanism. The support groove 305 is an arc-shaped structure with a groove on the upper part, on which a row of cylindrical rollers 307 are arranged to reduce friction during rolling. The wellbore bracket 306 is an arc-shaped component with a groove at the lower part, which sits on the support groove 305 with rollers 307, and the wellbore bracket 306 can slide along the arc-shaped rollers 307.

[0073] Furthermore, the locking mechanism 308 is a screw-lifting mechanism. The screw-lifting mechanism is raised or lowered by rotating the handwheel 309 to lock and unlock the wellbore bracket 306. After the locking mechanism 308 is unlocked, the wellbore bracket 306 can slide along the roller 307 to achieve angle adjustment. After the locking mechanism 308 is locked, the position of the wellbore bracket 306 relative to the support groove 305 is fixed. Figure 2 As shown.

[0074] In one specific embodiment of the present invention, the barrel support vehicle 4 includes: a barrel base 401, barrel wheels 402, and a barrel support 403; the barrel wheels 402 are rotatably mounted on both sides of the barrel base 401; the barrel support 403 is fixedly mounted above the barrel base 401, and the barrel support 403 has the same structure as the front support 3.

[0075] like Figure 3 , Figure 4 As shown, the cylinder support vehicle 4 consists of cylinder vehicle wheels 402, a frame, a lifting device, and a rolling device. It is placed on a base frame and can be manually pushed to move forward and backward along the guide rails on the base frame for adjusting the support position. A brake handwheel can stop the wheels. The function of the cylinder support vehicle is to support the weight of the well shaft and antenna, and it has forward, backward, up and down, and rolling direction adjustment functions. The lifting device and rolling device are modularly designed, the same as the front support component 3, see... Figure 3 .

[0076] Furthermore, the slot support vehicle 5 consists of a slot base 501, slot wheels 502, a circular slot bracket 503, and a lateral movement device 504. The lateral movement device 504 is installed on the slot base 501, and the circular slot bracket 503 is mounted on the slot base 501 via the lateral movement device 504. The circular slot bracket 503 can be manually pushed to move along the guide rail on the slot base 501 in the front-to-back direction to adjust the support position. The function of the slot support vehicle 5 is to bear the weight of the semi-circular slot 6 and the antenna 11, and it has front-to-back and left-to-right adjustment functions. The moving guide rail adopts a linear motion guide rail, such as... Figure 5 As shown.

[0077] In one specific embodiment of the present invention, the transverse movement device 504 includes a slide rail and a chute; the chute support 5 has a slide rail on its chute base 501; a chute is slidably installed above the slide rail, and a circular chute bracket 503 is fixedly installed above the chute; the semi-circular chute 6 is supported by the circular chute bracket 503; pushing the circular chute bracket 503 causes the chute to slide along the slide rail, thereby driving the semi-circular chute 6 to move horizontally.

[0078] Alternatively, the lateral movement device 504 can be implemented by using a helical ball screw or a screw-nut pair structure to achieve lateral displacement, and the lateral displacement of the circular slot bracket 503 can be achieved by rotating the screw.

[0079] In one specific embodiment of the present invention, the filling mechanism 7 includes: a filling frame 701, a gear 706, and a motor 9; the filling frame 701 is mounted above the semicircular groove 6; a rack 607 is provided on the upper end surface of the semicircular groove 6; the gear 706 is rotatably mounted on the filling frame 701, and the gear 706 meshes with the rack 607; the motor 9 can drive the gear 706 to rotate.

[0080] Furthermore, the motor 9 drives the gear 706 to rotate through a transmission mechanism; the transmission mechanism includes a gear shaft 705 and a gearbox 704; the motor 9 drives the gear shaft 705 to rotate through the gearbox 704.

[0081] Furthermore, the gearbox 704 is provided with a first bevel gear and a second bevel gear; the first bevel gear is installed at the end of the output shaft of the motor 9, and the second bevel gear is fixedly installed on the gear shaft 705 and sleeved on the outside of the gear shaft 705; two gears 706 are fixedly installed at both ends of the gear shaft 705; when the motor 9 is driven, the first bevel gear and the second bevel gear mesh and drive the two gears 706 to rotate synchronously.

[0082] Furthermore, a control box 8 is also provided, which is used to control the operation of the motor 9. The control box 8 is mainly designed with corresponding control functions around the frequency converter. The principle is that the frequency converter controls the operation of the motor 9 to realize the forward, backward, and stop movement of the loading mechanism 7. The control box 8 obtains the current absolute position of the device through an encoder installed on the motor 9, and controls different operating speeds of the loading mechanism 7 according to different positions, such as... Figure 7 As shown.

[0083] The loading mechanism 7 mainly consists of a U-shaped frame 702 and a loading frame 701. This mechanism is a moving part and moves together with the antenna 11 during the loading and unloading process. The loading mechanism 7 is mounted on the guide rail 601 of the semi-circular groove 6. The control box 8, motor 9, coupling, gear shaft 705, gearbox 704, and gear 706 are rotatably mounted on the loading frame 701. The gear 706 meshes with the rack 607 on the semi-circular groove 6. The motor 9 drives the gear 706 to rotate through the gearbox 704 and gear shaft 705, thereby driving the gear 706 to mesh with the rack 607. The gear 706 rolls along the rack 607, and the gear 706 drives the loading mechanism 7 to move on the rack 607. The loading mechanism 7 is displaced along the guide rail 601 of the semi-circular groove 6.

[0084] Furthermore, by controlling the forward or reverse rotation of the motor 9 via the control box 8, the forward or backward movement of the loading mechanism 7 can be controlled. By controlling the rotation angle and number of revolutions of the motor 9 via the control box 8, the travel of the loading mechanism 7 along the guide rail 601 can be controlled.

[0085] Furthermore, during the loading process, the loading mechanism 7 moves along the guide rail 601 of the semi-circular groove 6, and then, through the two forks of the U-shaped frame 702, it presses against the positioning pin on the well base 13, pushing the antenna 11, shock absorber 12, and well base 13 to slide and load on the skin 602 of the semi-circular groove 6; the two forks are equipped with hooks 703, which are rotatably connected to the U-shaped frame 702, and a spring connects the hooks 703 and the U-shaped frame 702. Compressing the spring causes the hooks 703 to rotate relative to the U-shaped frame 702, which can unlock or lock the hooks 703. When retracting the well, by pulling the hooks 703, the hooks 703 hook onto the positioning pin on the well base 13, and then, through the loading mechanism 7, the antenna 11, shock absorber 12, and well base 13 are moved, thus removing the antenna 11, shock absorber 12, and well base 13 from the well casing. Figure 7 , Figure 8 As shown.

[0086] In one specific embodiment of the present invention, the semicircular groove 6 is designed as a frame structure component, which has the characteristics of high specific stiffness and specific strength, such as... Figure 6 As shown.

[0087] Specifically, the semicircular groove 6 is mainly composed of guide rails 601, skin 602, front beam 603, rear beam 604, semicircular beam 605, stringers 606, and racks 607. The front beam 603 and rear beam 604 are both semicircular arcs and are connected by multiple stringers 606. Furthermore, the stringers 606 are reinforced by multiple semicircular beams 605. The front beam 603, rear beam 604, semicircular beam 605, and stringers 606 form a semicircular frame structure, primarily bearing the weight of the antenna, shock absorber, and well base. Further, skin 602 is laid on top of the semicircular frame to form the semicircular groove 6.

[0088] Furthermore, the ends of the front beam 603 and the rear beam 604 are connected by a guide rail 601, and a rack 607 is laid on the guide rail 601, which serves as the running track for the gear 706.

[0089] In one specific embodiment of the present invention, the in-well antenna horizontal loading device is further provided with a base plate 2 and support legs 1; the well shaft 10 and the semi-circular groove 6 are both disposed on the base plate 2; the base plate 2 is supported on the ground by the support legs 1, and the support legs 1 are used to adjust the level of the base plate 2. The front support 3, the well shaft support 4, and the groove support 5 are all disposed on the base plate 2; before aligning the well shaft 10 and the semi-circular groove 6, the base plate 2 is first leveled.

[0090] Furthermore, such as Figure 1As shown, multiple support legs 1 are installed on the base plate 2. The support legs 1 support the base plate 2 between it and the ground. The support legs 1 are connected to the base plate 2 by threads. By rotating the support legs 1, the distance between the base plate 2 and the ground can be adjusted, and the base plate 2 can be leveled. In other words, the support legs 1 are installed under the base plate 2 to support the base frame. The height of the support legs 1 can be manually adjusted to adapt to the unevenness of the ground. The structural rigidity of the base plate 2 ensures that the horizontal loading device is on a reference plane.

[0091] During implementation, the base plate 2 is manually supported by the support leg 1, and the level is adjusted by observing the level. The cylinder support carriage 4 and support carriage 5 are placed on the base frame guide rail. The semi-circular groove 6, filling mechanism 7, control box 8, and motor 9 are assembled and hoisted onto the groove support carriage 5. The well shaft 10 is then horizontally hoisted onto the front support 3 and the cylinder support carriage 4. By adjusting the lateral movement mechanism of the groove support carriage 5, and the lifting and rolling mechanisms of the cylinder support carriage 4 and the front support 3, the vertical, horizontal, and rolling positions of the well shaft 10 port are adjusted so that the inner wall of the well shaft 10 is flush with the ground. After the surfaces of the semicircular groove 6 are aligned to meet the docking size requirements, the installed antenna 11, shock absorber 12 and well base 13 are hoisted onto the semicircular groove 6 in a horizontal state. The motor 9 controlled by the control box 8 drives two gears 706 to reciprocate on the parallel rack 607, and drives the filling mechanism 7 and antenna 11 to slide horizontally along the guide rail 601. During the filling or removal process, different filling speeds can be selected to directionally load or remove the antenna 11 into or out of the well barrel 10, thus completing the antenna filling or removal process.

[0092] Compared with the prior art, the technical solution provided in this embodiment has at least one of the following beneficial effects:

[0093] 1. The loading device of the present invention can fulfill the purpose of horizontally loading and unloading antennas in a well within a technical plant. This horizontal loading device and method, utilizing an integrated structural and functional design, enables rapid and convenient docking and loading of the antenna and well casing.

[0094] 2. This invention achieves rapid docking and alignment of the antenna and wellbore in a horizontal state by setting up a base frame, a semi-circular groove, a front support, a barrel support vehicle, and a support vehicle. The motor drives the loading mechanism 7 to move forward or backward along the guide rail 601 of the semi-circular groove 6 through a gear and rack mechanism, realizing rapid horizontal loading or unloading.
