[0043] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] In the description of the present invention, "plurality" means two or more than two, unless otherwise precisely and specifically specified.

[0047] In addition, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not explicitly listed or inherent to such process, method, product, or apparatus.

[0048] Testing and wax removal are extremely important basic work in the process of oilfield development. Among them, reservoir testing is to use various instruments and meters, adopt different testing means and measurement methods, measure the dynamic and static data of the reservoir development process, and provide effective scientific data for the development of oilfields. In addition, wax deposition is often accompanied by oil wells in the process of oilfield development. Waxing of oil wells will lead to a decrease in the liquid production of oil wells. When wax deposition is serious, it will block the oil pipe and make the oil well unable to produce liquid. Therefore, wax removal is required to ensure that the oil pipe is normal and the liquid is produced smoothly.

[0049] Both testing and wax cleaning operations require that operating tools be placed into the well through the Christmas tree. In the prior art, a simple operating platform is built near the Christmas tree, and operators operate the Christmas tree on the operating platform. First, the plug on the valve at the top of the Christmas tree is removed, and then the blowout preventer, blowout preventer and other operating tools are hoisted onto the operating platform by a large crane. However, the large crane cannot accurately deliver the operating tools to the top of the valve of the Christmas tree, and the operator needs to manually place the operating tools into the Christmas tree. The tools used for wax cleaning and testing are long and heavy, which makes the entire operation inconvenient, thereby affecting work efficiency.

[0050] In order to avoid the operational difficulties of using existing work platforms to transport testing and wax removal tools into the oil tree, thereby affecting work efficiency, the present invention provides a work platform for testing and wax removal, which transports the testing and wax removal tools to the top of the oil tree through a lifting device arranged on the work surface, eliminating the need for manual operation by operators, thereby effectively improving work efficiency.

[0051] Figure 1 It is a structural schematic diagram of a first embodiment of an operation platform for testing and wax removal according to the present invention; Figure 2 It is a structural schematic diagram of a lifting device of a first embodiment of an operation platform for testing and wax removal of the present invention; Figure 3 This is a schematic diagram of the assembly structure of the first embodiment of the working platform for testing and wax removal of the present invention. Figures 1 to 3 The present invention provides a working platform for testing and wax removal, comprising: a working table 1, a supporting portion 2 and a lifting device 3; wherein one end of the supporting portion 2 is supported on the ground, and the other end of the supporting portion 2 is fixed to the working table 1; the lifting device 3 is installed on the working table 1, and the lifting device 3 is used to lift the working tool to the working table 1 and the top of the oil production tree 4.

[0052] Among them, the setting of the work surface 1 allows the operator to perform wax removal and testing operations without sitting on the Christmas tree 4. The operator can directly stand on the work surface 1 to open the valve at the top of the Christmas tree 4, and then put the tools used for testing and wax removal operations into the well through the Christmas tree 4, thereby avoiding the inconvenience caused by operating long and heavy working tools on the Christmas tree 4, and further improving the working efficiency. In addition, testing and wax removal operations on the work surface 1 also avoid the fall of working tools or even personnel, thereby preventing damage to the working tools and reducing the safety risks of the operating personnel.

[0053] The work surface 1 is generally arranged at a height not lower than the level of the Christmas tree 4, so that the operator can stand on the work surface 1 to open and close the valve at the top of the Christmas tree 4. At the same time, after the tools used for testing and wax removal are transported to the work surface 1 by the lifting device 3, the operator stands at a position higher than the top of the Christmas tree 4 to place the operating tools into the Christmas tree 4, and the entire operation process is more convenient, quick and relatively labor-saving.

[0054] The shape and size of the work surface 1 are not limited here, as long as it can ensure that the operator can smoothly place the blowout preventer, blowout preventer and other working tools used for testing and wax cleaning operations on the oil production tree 4, and at the same time ensure the personal safety of the operator.

[0055] Optionally, a railing 5 is provided around the work surface 1 to ensure that the operator is safer when performing testing and wax removal operations on the work surface, effectively reducing the risk of falling of the operator. At the same time, the provision of the railing 5 can also prevent the fall of the work tool. The provision of the railing 5 is not limited here, as long as it can be firmly provided around the edge of the work surface 1. For example, the railing 5 is detachably fixed to the work surface 1 to facilitate the removal of the railing 5. In addition, the railing 5 can also be welded to the work surface 1, so that the fixing between the railing and the work surface is more secure.

[0056] In order to allow the operator to conveniently enter the work surface 1, the railing 5 at the operator entrance of the work surface 1 is set as a detachable railing, or the railing 5 at this location is replaced by a chain 6. When in use, the operator opens the chain 6 before entering the work surface, and closes the chain 6 after entering. The setting of the chain 6 not only improves the safety performance of the work surface 1, but also allows the operator to enter the work surface 1 without crossing the railing 5, further reducing the safety risk.

[0057] The function of the support part 2 is to stably support the work surface 1 on the top of the Christmas tree 4. One end of the support part 2 is supported on the ground, and the other end of the support part 2 is fixed to the work surface 1.

[0058] The specific structure, layout and connection relationship of the support part 2 are not limited here, as long as the work surface 1 can be stably supported. For example, to ensure the stability of the work surface, the support part 2 can be a plurality of support legs 201 evenly arranged around the bottom surface of the work surface, and the support legs 201 are inclined at a certain angle to ensure that a single support leg 201 is stably supported on the ground. In addition, to strengthen the stability of the support legs 201, a fastener 202 can be arranged between adjacent support legs 201, and the fastener 202 can be a fastening rod fixed at both ends on two adjacent support legs 201. The number of fastening rods can be multiple, so that the multiple support legs 201 are more stable, thereby ensuring that the work surface 1 is more stable on the oil production tree 4, avoiding the shaking of the work surface 1 from affecting the entire operation process, and improving the operation efficiency to a certain extent. The support legs 201 and the fasteners 202 can be arranged in an integrated manner, or the fasteners 202 can be fixed to the support legs 201 in a detachable manner for easy disassembly. One end of the support leg 201 can be fixed at any position on the work surface 1. For example, one end of the support leg 201 can be fixed to the bottom surface of the work surface 1, or it can pass through the work surface 1, wherein the portion passing through the work surface 1 can be used as a railing, etc.

[0059] The support legs 201 are used as the support part 2 and are evenly arranged around the bottom surface of the work surface to ensure the stability of the entire work platform.

[0060] In addition, the support part 2 can also be a columnar support tube, one end of which is supported on the ground, and the other end of which is fixed on the work surface 1 to ensure that the work surface 1 is stably supported on the top of the Christmas tree 4.

[0061] The fixing method of the support part 2 and the work surface 1 is not limited here. For example, one end of the support part 2 can be welded to the work surface 1, or it can be integrally formed with the work surface to make the connection between the support part 2 and the work surface 1 more stable. The support part 2 can also be fixed to the work surface 1 in a detachable manner, such as snapping into a slot provided on the work surface 1, or sleeved into a sleeve provided at the bottom of the work surface 1, so that the assembly and disassembly between the support part 2 and the work surface 1 is faster and more convenient, thereby improving the applicability of the entire work platform.

[0062] Since the existing working platform is relatively simple, it needs to be used in conjunction with a large crane. The large crane lifts the working tools such as the blowout preventer and the blowout preventer onto the working platform, and the operator then puts the working tools into the Christmas tree for testing and wax removal. Since the large crane cannot accurately deliver the working tools to the valve top of the Christmas tree, and the tools used for wax removal and testing are long and heavy, the entire operation is inconvenient, which reduces the working efficiency. Therefore, in order to overcome the above-mentioned defects, a lifting device 3 is provided on the working table 1 of the present invention, and the lifting device 3 is used to lift the tools used for testing and wax removal to the top of the working table 1 and the Christmas tree 4; after the working tools are lifted to the top of the working table 1 and the Christmas tree 4 by the lifting device 3 in this embodiment, the operator slightly moves the working tools, and then the working tools can be placed into the well through the Christmas tree 4. The entire operation process is convenient and fast, and the working efficiency is improved.

[0063] Among them, the lifting device 3 can be installed at any position of the work surface 1, as long as it does not affect the lifting of the work tool by the lifting device 3. In order to facilitate the operator's auxiliary operation of the work tool, the lifting device 3 can be optionally installed at the edge of the work surface 1. Such a setting position makes it more convenient for the operator to stand on the work surface 1 to assist in the operation of the work tool suspended on the lifting device 3. At the same time, it also saves the space occupied by the lifting device 3 inside the work surface 1, facilitates the operator's operation, and improves the safety factor of the entire work platform.

[0064] The structural design of the lifting device 3 is intended to be simple, while also ensuring that the entire lifting operation is simple and accurate. Optionally, the lifting device 3 includes a first lifting arm 301, a second lifting arm 302 and a lifting rope 303; wherein, one end of the first lifting arm 301 is arranged on the work surface 1, and the first lifting arm 301 can rotate around its own axis, and the other end of the first lifting arm 301 is connected to the second lifting arm 302; the lifting rope 303 is wound around the pulley 304 of the second lifting arm for lifting working tools.

[0065] The first arm 301 on the lifting device 3 is used to support the second arm 302 and fix the lifting device 3 on the work surface 1. Optionally, the first arm 301 is perpendicular to the work surface 1, and the second arm 302 is perpendicular to the first arm 301, so that the various components of the entire lifting device 3 are more stable and the entire lifting process is smooth. In order to ensure that the lifting device 3 can automatically lift the working tools on the ground and transport them to the valve at the top of the oil production tree, the lifting device 3 itself needs to be able to rotate. Therefore, the first arm 301 is set on the work surface 1 and can rotate around its own axis. In this way, the second arm 302 is driven to rotate in the horizontal direction where it is located by the rotation of the first arm 301, and then the working tool is lifted to any desired position. In addition to setting the first arm 301 to be able to rotate around its own axis to realize the rotation of the entire lifting device 3, another way can also be used to achieve it, for example, the first arm 301 is fixed on the work surface 3, and the second arm 302 is movably set at the top of the first arm 301. Specifically, a slot can be set at the top of the first boom 301, and a connecting part can be set at one end of the second boom 302 perpendicular to its own axis. The connecting part is accommodated in the slot on the first boom 301. The second boom 302 can be rotated along a horizontal plane perpendicular to the first boom 301 by rotating the connecting part in the slot, thereby ensuring the horizontal movement of the working tool.

[0066] Among them, when the first suspension arm 301 can rotate around its own axis, the connection between the second suspension arm 302 and the first suspension arm 301 can be fixed, snap-fit ​​or integrated. Similarly, when the second suspension arm 302 can rotate along a horizontal plane perpendicular to the first suspension arm 301, the connection between the first suspension arm 301 and the work surface 1 can also be fixed, such as snap-fit ​​or integrated, as long as it can ensure that the various components of the entire lifting device 3 are stably connected and firmly fixed on the work surface 1.

[0067] Optionally, the first suspension arm 301 is a cylindrical tube with a hollow structure inside, and the suspension rope 303 is inserted from the bottom of the first suspension arm 301 and passed out from the top of the first suspension arm 301, and is wound around the pulley 304 provided on the second suspension arm 302, and the suspension rope 303 is wound around the pulley 304. When lifting the working tool, the rotation of the pulley 304 drives the suspension rope 303 to slide, reducing the resistance of the suspension rope 303 during the contraction process, making the entire lifting process faster, and at the same time, it also prevents the second suspension arm 302 from contacting and rubbing the suspension rope 303 for a long time, causing damage to the suspension rope 303. The setting of the pulley 304 prolongs the service life of the suspension rope 303, reduces the number of times the suspension rope 303 is replaced, and thus improves the working efficiency.

[0068] In order to reduce the sliding resistance of the suspension rope 303 on the second suspension arm 302 , optionally, pulleys 304 are respectively provided at both ends of the second suspension arm 302 , and the suspension rope 303 is wound around the two pulleys 304 in sequence.

[0069] Specifically, since the lifting rope 303 will inevitably rub against the boom during the extension and retraction process, in order to reduce the friction resistance of the lifting rope 303, pulleys 304 are respectively set at both ends of the second boom 302, and the lifting rope 303 is wound around the two pulleys 304. The lifting rope 303 will drive the pulley 304 to rotate during the extension and retraction process, thereby reducing the friction resistance of the lifting rope 303 and improving the lifting speed of the lifting rope 303.

[0070] There are many ways to fix the pulley 304 on the second hanging arm 302. Optionally, the second hanging arm 302 is configured as two parallel support arms, and a rotating shaft is respectively provided between the two ends of the two support arms, and the two pulleys 304 are respectively fixed on the rotating shaft. This configuration makes the connection between the pulley 302 and the second hanging arm 302 more stable. In addition, grooves can be respectively opened at both ends of the second hanging arm 302, and the two ends of the rotating shaft are respectively fixed on the inner wall of the groove, and then the pulley 304 is sleeved on the rotating shaft, which can also play a role in stabilizing the connection.

[0071] The lifting process of the suspension rope 303 can be operated manually or electrically. If it is operated manually, it is optional to set a winding wheel 305 at the bottom of the first suspension arm 301, and a part of the suspension rope 303 is wound on the winding wheel 305. The handle on the winding wheel 305 is manually rotated to realize the extension and contraction of the suspension rope 303. The specific structure of the winding wheel 305 is not limited here, as long as the extension and contraction of the suspension rope 303 can be guaranteed. In addition, the position of the winding wheel 305 may not be set at the bottom of the first suspension arm 301, and can be set at any position of the lifting device 3, and the winding wheel 305 is set at the bottom of the first suspension arm 301, so that the operator is more convenient to operate the suspension rope 303. If it is operated electrically, it is optional to connect a motor to the winding wheel 305, automatically drive the winding wheel 305 to rotate, realize the automatic extension and contraction of the suspension rope 303, improve the lifting operation efficiency, and save manpower. At the same time, the motor can effectively control the rotation speed of the winding wheel 305. When the lifting device 3 lifts the working tool from the ground to the working table 1, there is no need to accurately control the position of the working tool. Therefore, the lifting speed can be increased by increasing the rotation speed of the winding wheel 305. When the working tool is lifted to the vicinity of the top of the oil production tree 4, the rotation speed of the winding wheel 305 can be relatively reduced, so that the working tool slowly approaches the top of the oil production tree 4 and is placed inside the oil production tree 4, further ensuring the controllability and accuracy of the lifting device 3 during the entire lifting process.

[0072] Since the positions of the tools used for testing and wax removal on the ground and the position of the Christmas tree 4 relative to the lifting device 3 are relatively random, when the lifting device 3 lifts the working tools placed on the ground, it is necessary to ensure that the lifting rope 303 on the second lifting arm 302 can lift the working tools. When lifting the working tools to the work table 1, it is also necessary to ensure that the second lifting arm 302 can lift the working tools to the top position of the Christmas tree 1. Therefore, the second lifting arm 302 needs to be set as a structure with variable length to complete the lifting and placement of the entire working tool.

[0073] In order to accurately control the lifting position of the working tool during the entire test and wax removal operation, the second arm 302 of the lifting device 3 is set to a retractable structure. Optionally, the second arm 302 includes a fixed portion 306 and a sliding portion 307; wherein one end of the fixed portion 306 is fixed to the first arm 301, and the sliding portion 307 is slidably arranged on the fixed portion 306, so that the sliding portion 307 can move along the length direction of the fixed portion 306.

[0074] Specifically, the second arm 302 is configured to have a fixed portion 306 and a sliding portion 307 sequentially arranged along its own axial direction, and the sliding portion 307 can move along the length direction of the fixed portion 306 to change the length of the entire second arm 302, so that the range of motion of the second arm 302 is increased, and the relative position of the sliding portion 307 on the fixed portion 306 can be continuously adjusted according to the top position of the Christmas tree 4 to ensure that the working tool can be more accurately hoisted to the inside of the Christmas tree 4, reducing the workload of the operator. In addition, in order to facilitate the operator to perform other operations on the working tool hoisted on the work surface 1, the second arm 302 can be adjusted to a suitable length by moving the sliding portion 307, and the working tool can be placed at a suitable position on the work surface 1. This configuration not only facilitates the operator's operation, but also reasonably utilizes the space of the work surface 1.

[0075] The connection method between the fixed portion 306 and the sliding portion 307 of the second suspension arm 302 is not limited here, as long as it can ensure that the sliding portion 307 can move along the length direction of the fixed portion 306 to achieve variable length of the second suspension arm 302. Optionally, the fixed portion 306 is provided with a slide groove extending along its own axial direction, and the sliding portion 307 is provided with a slide rail matching the slide groove. The sliding portion 307 is partially disposed in the slide groove in the fixed portion 306 and moves along the slide groove to achieve the extension and retraction of the second suspension arm 302.

[0076] Specifically, the length of the second suspension arm 302 is determined by adjusting the position of the sliding portion 307 on the fixed portion 306. In other words, the second suspension arm 302 has different lengths when the sliding portion 307 moves different distances along the length direction of the fixed portion 306. Therefore, in order to adjust the second suspension arm 302 to a desired length, it is necessary to ensure that the sliding portion 307 can smoothly move along the length direction of the fixed portion 306 without deviation. In this embodiment, a slide groove extending along its own axial direction is provided on the fixed part 306, and at the same time, a slide rail matching the slide groove is provided on the sliding part 307. The sliding part 307 moves in the slide groove of the fixed part 306 through the slide rail, which not only reduces the resistance of the sliding part 307 during movement and improves the length adjustment efficiency of the first boom 302, but also the setting of the slide groove also plays a limiting role, so that when the sliding part 307 moves along the length direction of the fixed part 306, it is restricted by the slide groove and will not deviate to the left or right, thereby improving the connection stability between the sliding part 307 and the fixed part 306, so that the second boom 302 can ensure the stable connection of various components on the basis of realizing the telescopic function.

[0077] Optionally, the second boom 302 includes two parallel arms. To realize the telescopic function of the second boom 302, each arm includes a fixed portion 306 and a sliding portion 307. The specific arrangement is described in the above structural description of the second boom 302 and will not be repeated here.

[0078] On the basis of the above-mentioned embodiments, optionally, a connecting piece 7 is provided on the work surface 1, and the first boom 301 is rotatably connected to the work surface 1 through the connecting piece 7. The first boom 301 is connected to the work surface 1 through the connecting piece 7 so that the first boom 301 rotates around its own axial direction, thereby driving the second boom 302 to rotate, thereby realizing the lifting and transportation of the working tool.

[0079] The connecting member 7 can be a variety of structures, such as hinges, bearings, rotating sleeves, etc., as long as the first arm 301 can rotate around its own axis through the connecting member 7. Specifically, when the connecting member 7 is a bearing, the work surface 1 is fixed to the outer ring of the bearing, and the first arm 301 is sleeved on the inner ring of the bearing, thereby realizing the rotation of the first arm 301. At the same time, the setting of the bearing also effectively reduces the friction resistance of the first arm 301 when rotating on the work surface 1, so that the rotation of the first arm 301 is faster, further improving the working efficiency. Optionally, the connecting member 7 includes a sleeve arranged on the work surface 1, one end of the first arm 301 is sleeved in the sleeve, and the fixing of the sleeve realizes the rotation of the first arm 301. This connection method has a simple structure and is easy to assemble. In order to ensure that the connection between the first suspension arm 301 and the sleeve is more stable, a fastener can be arranged between the sleeve and the first suspension arm 301. The fastener can be a fastening ring mounted on the sleeve near the opening, and spring pins are respectively arranged on both side walls of the fastening ring. The setting of the spring pins further improves the stability between the first suspension arm 301 and the sleeve.

[0080] In addition, in order to realize the lifting function of the entire lifting device 3, an internal thread can be set in the sleeve, and an external thread matching the internal thread can be set on the outer wall of the first arm 301. Through the matching connection of the threads, not only the rotation of the first arm 301 can be realized, but also the extension and contraction of the first arm 301 can be realized, thereby driving the second arm 302 to move up and down along the axis of the first arm 301, and at the same time, the connection between the first arm 301 and the sleeve is more stable. Since the working tool is long, when the lifting device 3 lifts the working tool to the working table 1, in order to avoid the working tool constantly touching the working table 1, the second arm 302 can be raised by rotating the first arm 301 to a certain distance, and at the same time, personal injury to the operator is avoided. When the working tool 1 reaches the top of the Christmas tree 4, the first arm 301 is rotated in the opposite direction to make the second arm 302 drop a certain distance, and the working tool is directly placed in the well through the Christmas tree 4, which effectively reduces the inconvenience caused by human operation, improves work efficiency, and reduces safety risks.

[0081] On the basis of the above-mentioned embodiment, optionally, the working platform also includes a ramp 8, one end of which is arranged on the working surface 1, and the other end is supported on the ground. The ramp 8 is used to support the working tool when hoisting the working tool, and plays a role in auxiliary lifting.

[0082] Since the tools used in testing and wax cleaning operations are heavy and long, the lifting device 3 is prone to the working tools swinging randomly and accidentally injuring the operator during the process of lifting the working tools, or the lifting rope is broken due to the heavy tools. Therefore, in the process of lifting the working tools to the work table 1, some auxiliary supporting structures of the working tools are set on the work platform to avoid the above situation. In this embodiment, the ramp 8 is set between the work table and the ground. In the process of lifting the working tools by the lifting device 3, the working tools are supported on the ramp 8, which prevents the working tools from swinging during the lifting process and plays a good supporting role, ensuring the efficiency and safety of the entire lifting process.

[0083] Among them, the ramp 8 can be tilted at a certain angle so that the working tools can be better supported during the lifting process, avoiding damage to the lifting device 3 due to the heavy working tools, which affects the working efficiency. In addition, there are many ways to connect the ramp 8 to the working table 1, and there is no restriction here. For example, one end of the ramp 8 is clamped on the working table 1 to facilitate the movement of the ramp 8. In this way, the ramp 8 can be adaptively adjusted according to the setting position of the lifting device 3, which is convenient for the ramp 8 to assist in supporting the working tools during the lifting process. In some examples, one end of the ramp 8 can also be welded to the working table 1 to make the ramp 8 more stable.

[0084] In order to further prevent the working tool from swinging on the ramp 8, the specific structure of the ramp 8 is further optimized, for example, baffles are respectively provided on both sides of the ramp 8, or the shape of the cross section of the ramp 8 perpendicular to its own axis is adjusted to prevent the working tool from swinging left and right. Optionally, the shape of the cross section of the ramp 8 perpendicular to its own axis is an arc, so that the edges of both sides of the ramp 8 are convex structures, thereby ensuring the stability of the working tool during the hoisting process.

[0085] At the same time, in order to facilitate the work tool to be directly hoisted from the ramp 8 to the work surface, the railing on the work surface 1 at the exit of the ramp 8 is set as a detachable railing stopper, or a chain 6 is set at the exit of the ramp 8. For example, before the lifting device 3 hoists the work tool to the work surface, the chain 6 is in an open state. After the work tool is transferred from the ramp 8 to the work surface 1, the chain 6 is locked to the railing on one side, which not only facilitates the work tool to enter the work surface 1, but also improves the safety factor of the work platform.

[0086] On the basis of the above-mentioned embodiments, the working platform may further include a ladder 9, one end of which is arranged on the working table 1, and the other end of which is supported on the ground. The operator climbs up to the working table 1 via the ladder 9 to complete the testing and wax removal operations. The ladder 9 may form any angle with the ground to improve the safety of the entire operation. Optionally, the ladder 9 may be arranged as an inclined ladder, that is, the angle between the ladder 9 and the ground is an acute angle, and such an arrangement further reduces safety hazards.

[0087] The ladder 9 can be set at any position on the work surface. In order to facilitate the operator to perform auxiliary operations on the working tools in the ramp 8, the ladder 9 can be optionally set on the side of the ramp 8. When the working tools move in the ramp 8, the operator can stand on the ladder 9 to perform auxiliary operations on the working tools to ensure the stability of the working tools during the lifting process.

[0088] In order to facilitate the operator to stand on the work surface 1 to perform corresponding operations on the valve at the top of the oil production tree 4, optionally, an operating port 10 for the valve at the top of the oil production tree to pass through is opened on the work surface 1. The operator can directly operate the oil production tree 4 through the operating port 10 on the work surface 1 to complete the test and wax cleaning operations without having to extend the body out of the work surface 1 to operate. The setting of the operating port 10 not only facilitates the operator's operation and improves the operating efficiency, but also reduces the safety risk.

[0089] The position of the operating port 10 on the work surface 1 is not limited here. For example, the operating port 10 can be set at the edge of the work surface 1 or inside the work surface 1. The cross-sectional shape of the operating port 10 is various, including semicircular, circular or polygonal, and the cross-sectional size of the operating port 10 is as large as possible from the cross-sectional size of the top valve of the Christmas tree 4. In this way, it is more convenient to perform wax cleaning and testing operations on the Christmas tree through the operating port 10, further improving the operating efficiency.

[0090] The present embodiment provides a work platform for testing and wax removal, comprising: a work surface, a support part and a lifting device; wherein one end of the support part is supported on the ground, and the other end of the support part is fixed to the work surface; the lifting device is installed on the work surface, and the lifting device is used to lift the work tool to the work surface and the top of the Christmas tree. The work platform for testing and wax removal provided by the present invention can avoid the operational difficulties of using the existing work platform to transport the testing and wax removal work tools into the Christmas tree, thereby affecting the work efficiency. The testing and wax removal work tools are transported to the top of the Christmas tree by the lifting device arranged on the work surface, without the need for manual operation by the operator, which effectively improves the work efficiency and reduces the safety hazards generated by the entire operation process.
