Description

Technical Field

[0001] The invention relates to the technical field of drilling, and in particular to an adjusting component of a choke and well-killing manifold. Background Art

[0002] During oil and gas drilling, uncontrolled formation fluids can lead to kicks or uncontrolled blowouts. These can complicate downhole conditions, disrupt normal drilling operations, and even damage drilling equipment and oil and gas resources, endangering the safety of both the drillers and the well. A choke and kill manifold is a specialized manifold equipped with adjustable flow valves. During well-killing operations, the choke and kill manifolds can be adjusted to apply a certain back pressure to the well and constrain the fluid through the manifolds, allowing it to flow under control or change direction. These manifolds are essential for controlling kicks and implementing oil and gas well pressure control technologies.

[0003] The choke and kill manifold is an indispensable well control device for implementing the balanced drilling process. During the drilling process, when the normal method of mud circulating downward through the drill pipe is out of control, the device can be directly connected to the mud pump to pump mud into the well, thereby achieving the purpose of controlling the pressure of the oil and gas well. There are two types of existing choke and kill manifold devices: one is a fixed structure device with an unadjustable height, and the other is a height-adjustable device. The defect of the fixed structure device is that the height cannot be adjusted according to actual use on site. Most of the existing height-adjustable devices are a fixed structure and are connected through a drive structure, which causes the drive structure to occupy a large amount of space. On the site of use, some installation spaces are limited and the ground is not flat, which causes the equipment with a large adjustable height device to be unable to be installed in place. Most of the height-adjustable devices cannot be adjusted according to the unevenness of the site. The ground can only be leveled before the choke and kill manifold is installed. The project volume is large, the adaptability is not strong, and there are great difficulties in use. Summary of the Invention

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art in that a throttle and well-killing manifold has high requirements on the site and low adaptability when adjusting the height, and to provide an adjustment component for a throttle and well-killing manifold.

[0005] In order to achieve the above-mentioned purpose, the embodiment of the present invention specifically adopts the following technical scheme: an adjustment component of a throttling and well-pressing manifold, comprising a mounting platform, a manifold group is provided on the upper part of the mounting platform, a plurality of mounting seats are provided on the side of the mounting platform, a support device capable of adjusting the height is provided on the mounting seat, the support device comprises a support leg connected to the mounting seat, a connecting head is provided on the top of the support leg, an adjustment leg is provided on the lower part of the support leg, and the adjustment leg is connected to the upper part of the support leg via a connecting device.

[0006] Furthermore, the mounting seat is arranged on the side of the mounting platform, the connecting head is a spherical head, and a locking bolt for locking the connecting head is arranged on the side of the mounting seat.

[0007] Furthermore, a plurality of connecting columns are provided on the upper side of the supporting leg, an adjusting ring is rotatably provided on the side of the adjusting leg, and an adjusting rod for connecting with the connecting columns is provided on the side of the adjusting ring.

[0008] Furthermore, the connecting device is one of a spherical seat, a rotating shaft, and a universal joint.

[0009] Furthermore, a driving motor is provided on the upper surface of the mounting platform, a through slot for connecting a plurality of mounting seats is provided inside the mounting platform, and a connecting shaft is provided inside the through slot.

[0010] Furthermore, the mounting seat is arranged on the side of the mounting platform, the through slot is arranged inside the edge of the mounting platform, and at least three connecting shafts are provided to connect with the driving motor.

[0011] Furthermore, the drive motor is arranged at the intersection of the two connecting shafts, the output end of the drive motor is provided with a drive wheel, and the end of the connecting shaft is provided with a connecting wheel connected to the drive wheel.

[0012] Furthermore, a collar for connecting the screw rod is provided inside the connecting head, and the collar is connected to the connecting shaft through a speed change device. A through hole for passing the screw rod is provided in the middle position of the connecting head and the support leg, and the collar is provided at the upper part of the through hole. Teeth cooperating with the screw rod are provided on the inner wall of the collar, and the teeth protrude from the inner wall of the through hole.

[0013] Furthermore, a driving gear is provided on the outer side of the collar, and a transition gear is provided between the driving gear and the speed change device.

[0014] Furthermore, the speed change device includes a clutch shaft controllably connected to the transition gear.

[0015] The beneficial effects of the embodiments of the present invention are as follows: the lower part of the support leg is provided with an adjusting leg. By adjusting the angles among the mounting seat, the support leg and the adjusting leg, under installation conditions in a complex ground environment, the support leg and the adjusting leg can be adjusted to different rotation angles to avoid positions that are not suitable for support, so as to adapt to different terrains. The angle between the support leg and the adjusting leg can be adjusted to support different heights of the mounting platform, thereby greatly improving the applicability. At the same time, the overall structure can be folded, which reduces the occupied space compared with the structure in the prior art.

[0016] If a higher fulcrum is required, a screw rod can be used, and the other fulcrums can be supported by adjustment legs and adjustment rods. Through the coordinated work of independent adjustment units, it can adapt to complex terrain and ensure the horizontal stability of the mounting platform. Through manual and electric dual adjustment mechanisms, a wide range of flexible height adjustments can be achieved to meet the installation requirements under different terrain conditions, allowing the mounting platform to adapt to complex terrain without the need for additional ground treatment, thereby reducing installation costs.

The mounting platform 1 is arranged in a rectangular shape, and the mounting seats 4 are arranged at the four corners. A leg 2 for adjusting the support height is provided on each mounting seat 4. A connecting head 3 is provided on the top of the leg 2. The connecting head 3 uses a spherical head. The connecting head 3 is rotatably connected to the mounting seat 4, thereby driving the leg 2 to rotate within a certain range with the mounting seat 4 as the connection point, and the leg 2 can be rotated to be flush with the mounting platform 1 during transportation and storage, which greatly reduces the occupied space and improves the use effect. A locking bolt for locking the connecting head 3 is provided on the side of the mounting seat 4. When rotated to the set angle, the locking bolt is used to lock the connecting head 3 to ensure stability.

[0029] The lower part of the support leg 2 is provided with an adjusting leg 201, and the connection between the adjusting leg 201 and the upper part of the support leg 2 is connected by a spherical seat, a rotating shaft, or a universal joint, so that the adjusting leg 201 and the upper part of the support leg 2 can generate a rotation angle within a certain range. By adjusting the angles between the mounting seat 4, the support leg 2 and the adjusting leg 201, under the installation conditions of a complex ground environment, the different rotation angles of the support leg 2 and the adjusting leg 201 are adjusted to avoid positions that are not suitable for support to adapt to different terrains. The upper side of the support leg 2 is provided with a plurality of connecting columns 204 in different positions and directions, and the side of the adjusting leg 201 is provided with an adjusting ring 202 for rotation. The side of the adjusting ring 202 is provided with an adjusting member for connection with the connecting column 204 Rod 203, after adjusting the angle, rotate the adjusting rod 203 so that the top of the adjusting rod 203 is connected to the connecting column 204 on the upper part of the leg 2, and tighten it with a nut, so that a stable triangular connection is formed between the three, ensuring the supporting stability of the leg 2 and the use effect. A shorter support column 401 is also provided on the bottom surface of the mounting seat 4. If the distance is lower than the ground, the support column 401 can be used directly for support. If the distance is higher, the leg 2 needs to be opened and the angle between the leg 2 and the adjusting leg 201 is adjusted to support different use heights of the mounting platform 1, which greatly improves the applicability.

[0030] A through slot is provided on the side of the mounting platform 1. The through slot can be opened in the width and length directions of the mounting platform 1, or it can be a position where the upper and lower plates of the mounting platform 1 are welded and left empty in the middle, or it can be inside the space below the upper surface of the mounting platform 1. As long as the connecting shaft 5 can be installed, multiple mounting platforms 1 can be connected using the connecting shaft 5 to achieve synchronous movement. A driving motor 6 is provided on the upper surface of the mounting platform 1. The top motor is installed vertically, and the output end is set below the upper surface of the mounting platform 1. A driving wheel 601 is provided at the output end. The driving wheel 601 adopts a helical gear with teeth set on the side. The connecting shaft connected to the driving wheel 601 The end of the connecting shaft 5 is provided with a connecting wheel connection, which changes the direction of the horizontal rotating power and the axial movement of the connecting shaft 5. The power is transmitted to the inside of the mounting seat 4 through the intermediate shaft 602 near the mounting seat 4 of the drive motor 6. At the same time, if the connecting shaft 5 of the remaining mounting seats 4 cannot be directly extended into the inside of the mounting seat 4, it is transferred through the intermediate shaft 602 to achieve synchronous transmission of power. A worm gear structure is used on the intermediate shaft 602 in the lower left corner to drive the connecting shaft 5 to rotate, and different gear ratios are used to adjust the rotation rates of the three connecting shafts 5 to the same, so as to achieve synchronous power output, meet the use requirements of simultaneous control, and ensure the control effect.

[0031] A bevel gear is provided at the end of the intermediate shaft 602, a clutch shaft 603 is provided inside the mounting seat 4 along the length direction, an operating hole is provided on the upper part of the mounting seat 4, a connecting rod 403 connected to the outside is provided inside the operating hole, the other end of the connecting rod 403 is connected to the power source 402, wherein the power source 402 can be a structure with a telescopic function such as a cylinder, an electric push rod, an electromagnetic valve seat, etc., and the clutch shaft 603 is driven to move along the length direction through the connecting rod 403, and a connecting gear connected to the bevel gear on the intermediate shaft 602 is provided at the end of the clutch shaft 603, and a bevel gear is provided at the other end of the clutch shaft 603 to be connected to the driving member inside the connector 3, and the connector 3 is provided with a tapered mouth on the inside of the mounting seat 4, and the connector 3 is provided inside.

At this time, the adjusting rod 203 can be removed. When the leg 2 is vertical, the conical mouth is aligned with the bevel gear on the clutch shaft 603. At this time, the power source 402 is started to move the clutch shaft 603 to the left, so that the bevel gear on the clutch shaft 603 is engaged with the transition gear 304. The other end of the clutch shaft 603 is connected to the intermediate shaft 602, and the driving motor 6 rotates to drive the ring 302 to rotate, and then drives the screw rod to move downward, so that the mounting platform 1 moves up as a whole. When different heights need to be adjusted, screw rods of different lengths can be selected. The bottom of the screw rod is from the adjusting leg 2 The bottom of 01 is unscrewed. For ease of use, a bottom plate can be set at the bottom of the screw to prevent the screw from sinking and ensure stability when moving up. When adjusted to the set height, the locking bolt is locked to help maintain stability. When the four support points are at different heights, the screw can be extended to different lengths, and each leg 2 can be controlled relatively independently. If the height difference between each fulcrum is large, a screw can be used for the fulcrum that requires a higher height, and the other fulcrums can be supported by the adjustment leg 201 and the adjustment rod 203. Through the coordinated work of independent adjustment units, it can adapt to complex terrain and ensure the horizontal stability of the mounting platform 1. The screw rotates up or down in the threaded hole inside the spherical connector 3 to achieve precise height adjustment. The screw lifting mechanism is designed with a self-locking function.Ensure that it will not fall due to gravity in the event of a power outage, ensuring stability and improving safety.

[0032] When in use, first evaluate the required height adjustment range according to the terrain conditions of the drilling site, determine whether a screw is needed, and if necessary, select the appropriate screw length, install the adjustment support structure on the side of the mounting platform 1, connect the drive motor 6 and the transmission shaft, debug the self-locking function of the screw lifting mechanism, start the drive motor 6, input the target height through the control panel, and the drive system automatically adjusts to the specified position. The locking mechanism ensures stability. After completing the height adjustment, perform a comprehensive safety check to ensure that all components are firmly connected and there is no looseness. Through the manual and electric dual adjustment mechanisms, a wide range of flexible adjustment of the height can be achieved to meet the installation requirements under different terrain conditions, so that the mounting platform 1 can adapt to complex terrain without additional treatment of the ground, reducing installation costs.
