[0051] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0052] Embodiment 1:

[0053] like Figure 1 As shown, the present invention provides an integrated horizontal oil production wellhead device, comprising:

[0054] A wellhead device body, the wellhead device body comprises a Christmas tree 1 and a Christmas tree valve 2 located at the top of the Christmas tree 1;

[0055] The positioning assembly frame 3 is provided with an angle control unit, an upper clamping unit and a lower clamping unit in sequence from top to bottom; the upper clamping unit is used to clamp the Christmas tree valve 2, the lower clamping unit is used to clamp the Christmas tree 1, and the angle control unit is used to adjust the angle of the Christmas tree valve 2;

[0056] Position sensors are respectively arranged on flanges connecting the Christmas tree 1 and the Christmas tree valve 2, and are used to detect whether the Christmas tree 1 and the Christmas tree valve 2 are in a preset installation position. The controller controls the angle control unit according to the position detection signal.

[0057] The working principle and beneficial effects of the above technical solution are:

[0058] The present invention provides an integrated horizontal oil production wellhead device, wherein the wellhead device body comprises an oil production tree 1 and an oil production tree valve 2. When in use, the oil production tree valve 2 needs to be installed on the oil production tree 1, and the oil production tree 1 is assembled with an oil production pipeline. By setting a positioning assembly frame 3, an upper clamping unit clamps the oil production tree valve 2, and a lower clamping unit clamps the oil production tree 1, and the two are assembled together. The positioning assembly frame 3 is moved to the position of the oil production pipeline, and the bottom end of the oil production tree 1 is assembled with the oil production pipeline.

[0059] The position sensor includes a distance sensor, which can detect the top flange of the Christmas tree 1 and the bottom flange of the Christmas tree valve 2. The positioning assembly frame 3 controls the height of the upper clamping unit and the lower clamping unit according to the distance detection result, so that the flanges of the two are in contact. The position sensor also includes a position sensing block. After the flanges of the Christmas tree 1 and the Christmas tree valve 2 are in contact, the angle control unit is started to adjust the relative angle of the Christmas tree 1 and the Christmas tree valve 2 so that the position sensing blocks on the two flanges correspond to each other, thereby achieving accurate installation of the Christmas tree 1 and the Christmas tree valve 2.

[0060] The present invention provides an integrated horizontal oil production wellhead device, which adopts the arrangement of a positioning assembly frame 3 to realize the rapid installation between the Christmas tree 1 and the Christmas tree valve 2, and between the Christmas tree 1 and the oil production pipeline, greatly reducing the difficulty of operation and being convenient and quick; and based on the position detection result, the action of the clamping unit and the angle control unit is controlled, so that the Christmas tree 1 and the Christmas tree valve 2 can be accurately installed at a preset angle, which is convenient for the subsequent arrangement of the oil production pipeline and improves the assembly reliability of the oil production wellhead device.

[0061] Embodiment 2:

[0063] The working principle and beneficial effects of the above technical solution are:

[0064] The lifting frame 13 of the positioning assembly frame 3 is set to a multi-stage lifting type, and each lifting section of the lifting frame 13 is hydraulically driven; the second lifting section 132 can rise or fall relative to the first lifting section 131, and the third lifting section 133 can rise or fall relative to the second lifting section 132. When the Christmas tree 1 and the Christmas tree valve 2 are installed, the third lifting section 133 is driven to descend so that the Christmas tree valve 2 contacts the Christmas tree 1; when the Christmas tree 1 is connected to the oil production pipeline, the second lifting section 132 is driven to descend so that the overall height of the wellhead device formed by the Christmas tree valve 2 and the Christmas tree 1 is reduced, which is convenient for connecting to the oil production pipeline. Universal wheels 14 are set on the bottom plate 11, which can quickly move the positioning assembly frame 3 to the wellhead position; the grooves on the bottom plate 11 can avoid the wellhead and the Christmas tree 1.

[0065] Embodiment 3:

[0066] like Figure 1 , 2 As shown, based on the above embodiment 1, the lower clamping unit includes two clamping jaws with adjustable spacing, and the clamping jaws are stably clamped on the surface of the Christmas tree 1.

[0067] The working principle and beneficial effects of the above technical solution are:

[0068] The clamps are connected to the second lifting section 132. The two clamps are arranged in an arc shape so as to fit tightly with the surface of the Christmas tree 1. The distance between the two clamps is adjustable so as to ensure that the clamps do not interfere with valves and other components on the surface of the Christmas tree 1 when clamping the Christmas tree 1.

[0069] Embodiment 4:

[0070] like Figure 1 , 4 As shown, based on the above embodiment 2, the angle control unit includes:

[0071] A driving box 21, the driving box 21 is connected to the top of the third lifting section 133;

[0072] The adapter 22 is connected to the output end below the driving box 21;

[0073] The turntable assembly is connected between the adapter 22 and the upper clamping unit. The adapter 22 drives the upper clamping unit to rotate through the turntable assembly.

[0074] The working principle and beneficial effects of the above technical solution are:

[0075] When the angle control unit is in use, a rotation output end is provided at the bottom end of the driving box 21. The output end of the driving box 21 drives the turntable assembly to rotate through the adapter 22, thereby driving the upper clamping unit to rotate.

[0076] Embodiment 5:

[0077] like Figure 4-7 As shown, based on the above-mentioned embodiment 4, the upper clamping unit includes:

[0078] A circular ring 23, which is disposed below the rotary disk assembly. The diameter of the circular ring 23 is larger than the diameter of the flange at the bottom end of the Christmas tree valve 2. Four lugs 24 are evenly connected to the outer wall of the circular ring 23.

[0079] Clamping cylinders 25, four clamping cylinders 25 are evenly connected to the outer wall of the ring 23, and are arranged alternately with the lugs 24, and the output ends of the clamping cylinders 25 extend into the ring 23;

[0080] The clamping plate 26 is connected to the output end of the clamping cylinder 25 , and the inner wall of the ring 23 is provided with a groove 27 for accommodating the clamping plate 26 .

[0081] The working principle and beneficial effects of the above technical solution are:

[0082] When the upper clamping unit clamps the Christmas tree valve 2, the Christmas tree valve 2 is placed in the circular ring 23; the diameter of the circular ring 23 is larger than the overall outer dimensions of the Christmas tree valve 2, so that the Christmas tree valve 2 as a whole does not interfere with the circular ring 23; the flange at the bottom of the Christmas tree valve 2 is aligned with the circular ring 23, the clamping cylinder 25 is started, the output end of the clamping cylinder 25 extends, and the clamping plate 26 is pushed to move toward the center of the circular ring 23 until the clamping plate 26 contacts the flange of the Christmas tree valve 2; the four clamping cylinders 25 act synchronously to fix the Christmas tree valve 2 at the center of the circular ring 23, thereby playing a role in stably clamping the Christmas tree valve 2, and facilitating the position adjustment of the Christmas tree valve 2. The flange at the bottom of the Christmas tree valve 2 is used as a clamping point. On the one hand, the flange is the position where the diameter of the Christmas tree valve 2 body is the largest. Clamping here can improve the stability of the Christmas tree valve 2 and avoid the components on the Christmas tree valve 2. On the other hand, after the Christmas tree 1 and the Christmas tree valve 2 are assembled to form a wellhead device, when adjusting the overall angle of the wellhead device, by clamping at the flange, the clamping diameter is relatively large, the force on the wellhead device is more uniform, and the torque on the wellhead device body during the adjustment process is reduced.

[0083] Embodiment 6:

[0084] like Figure 4-7 As shown, based on the above embodiment 5, the turntable assembly includes:

[0085] Support plate, the support plate is connected to the bottom end of the drive box 21 through a support plate 28;

[0086] The center wheel 29 is connected to the center of the upper part of the support plate through the center shaft 31, and the center shaft 31 is connected to the adapter 22;

[0087] Planetary gears 32, four planetary gears 32 are evenly arranged around the central gear 29 and meshed with the central gear 29, and the rotating shafts of the planetary gears 32 are connected above the support plate;

[0088] Screw shafts 33, four screw shafts 33 are rotatably connected to the bottom of the support plate, the top ends of the screw shafts 33 are connected to the rotating shafts of the planetary gears 32, and the screw shafts 33 are connected to the threaded holes in the centers of the lugs 24;

[0089] The limiting plate 34 is connected to the bottom end of the screw shaft 33 and is located below the lug 24 .

[0090] The working principle and beneficial effects of the above technical solution are:

[0091] When the turntable assembly is in use, when the support disk is in a locked state, the output end of the drive box 21 drives the adapter 22 to rotate, and the adapter 22 drives the central shaft 31 to rotate synchronously therewith, and the central shaft 31 drives the central wheel 29 to rotate at the center of the support disk, and the central wheel 29 meshes with the four planetary wheels 32, driving the four planetary wheels 32 to rotate around themselves, and the rotating shafts of the planetary wheels 32 drive the screw shaft 33 to rotate synchronously, and the screw shaft 33 performs threaded transmission in the threaded hole on the lug 23, thereby driving the lug 23 to move on the screw shaft 33 , the limit plate 34 can limit the moving range of the lug 24; the screw shaft 33 and the lug 23 are both set to four, so that the four lugs 23 drive the ring 23 to move, and the direction is along the length direction of the screw shaft 33 without twisting, thereby realizing the adjustment of the height of the ring 23, that is, the adjustment of the height of the upper clamping unit; it can adapt to the Christmas tree valve 2 of different heights, when the Christmas tree 1 and the Christmas tree valve 2 are connected, a small adjustment is performed as a supplement to the second lifting section 132, so as to improve the assembly accuracy of the device.

[0092] Embodiment 7:

[0094] A state switching component is provided on the support plate, and the state switching component includes:

[0095] Fixed blocks 41, four fixed blocks 41 are evenly connected to the outer wall of the first ring 35;

[0096] An electric push rod 42, the electric push rod 42 is horizontally mounted on the fixed block 41, and the output end of the electric push rod 42 extends toward the center of the first ring 35;

[0097] A limit rod 43, the limit rod 43 is connected to the output end of the electric push rod 42;

[0098] Limiting blocks 44, four limiting blocks 44 are evenly connected to the second ring 36, and limiting holes 45 corresponding to the limiting rods 43 are provided on the limiting blocks 44;

[0099] The first sleeve 46 is connected to the center of the center disk 37, and the inner wall of the first sleeve 46 is provided with electromagnetic blocks, the center shaft 31 extends into the first sleeve 46, and magnetic segments are provided at corresponding positions of the center shaft 31 and the first sleeve 46;

[0100] A second sleeve 47, four second sleeves 47 are evenly connected to the second ring 36, and the second sleeve 47 is sleeved on the outer side of the screw shaft 33;

[0101] The connecting rod 48 is connected between the second sleeve 47 and the first sleeve 46 .

[0102] The working principle and beneficial effects of the above technical solution are:

[0103] The support plate is set in the form of a circular ring combination, and the movement mode of the angle control unit is changed through the state switching component.

[0104] When the state switching component is set to the locked state, the output end of the start-up electric push rod 42 is extended, driving the limit rod 43 to move toward the center of the first ring 35, so that the limit rod 43 is clamped in the limit hole 45 of the limit block 44; the electric push rod 42 is arranged on the first ring 35, and the limit block 44 is arranged on the second ring 36, thereby connecting the first ring 35 and the second ring 36 into one, and the positions of the second sleeve 47 and the screw shaft 33 remain unchanged, and the screw shaft 33 can only rotate around its own axis; and the electromagnetic block on the first sleeve 46 is powered off, losing the attraction to the center shaft 31, and the center shaft 31 can rotate freely relative to the center disk 37; at this time, the drive box 21 is actuated to drive the screw shaft 33 to rotate, so that the lug 24 moves up and down, thereby realizing the adjustment of the height of the upper clamping unit, which is the first movement mode of the angle control unit.

[0105] When the state switching component is set to the unlocked state, the output end of the start-up electric push rod 42 is retracted, driving the limit rod 43 to move in the direction away from the center of the first ring 35, so that the limit rod 43 is separated from the limit hole 45 and the limit is released, and the second ring 36 and the first ring 35 can rotate relative to each other; at the same time, the electromagnetic block on the first sleeve 46 is energized to generate an attraction to the central axis; driven by the connecting frame formed by the first sleeve 46, the second sleeve 47 and the connecting rod 48, the central disk 37, the central axis 31 and the second ring 36 are formed into one; the rotation of the central axis 31 can drive the second ring 36 to rotate, and then drive the four screw shafts 33 to rotate with the central disk 37 as the center, and the four screw shafts 33 drive the upper clamping unit to rotate synchronously, thereby realizing the adjustment of the angle of the upper clamping unit. This is the second motion mode of the angle control unit.

[0106] Through the above structural design, the switching of the movement mode of the angle control unit is effectively realized, so that the angle control unit has the functions of height adjustment and angle adjustment. On the one hand, the angle control unit can adjust its internal space through height adjustment to adapt to different heights of the Christmas tree valve 2, and can achieve the height fine-tuning function to ensure that the Christmas tree 1 and the Christmas tree valve 2 are in full contact; on the other hand, the relative angle between the Christmas tree valve 2 and the Christmas tree 1, and the relative angle between the wellhead device body and the oil production pipeline are adjusted, so that the wellhead device body can be installed in a preset direction, which is convenient for the layout of subsequent oil production equipment and reduces the risk of leakage caused by installation angle deviation.
