Description

Technical Field

[0001] This utility model relates to the field of oil pipe maintenance technology, specifically to an oil pipe dewaxing device. Background Technology

[0002] During oil well production, sludge and wax (hereinafter referred to as oil wax) adhere to the inner wall of the tubing, affecting the normal production of the oil well. Therefore, tubing piercing operations are required to remove the oil wax adhering to the inner wall of the tubing. The main process of tubing piercing includes: pulling the tubing out from downhole and placing it on a support, then inserting a gauge into one end of the tubing, and using steam to push the gauge out from the other end of the tubing. At the same time, the oil wax in the tubing is discharged from the tubing along with the gauge. However, this type of wax removal method requires continuous injection of high-temperature steam into the tubing, which increases the actual energy consumption during the wax removal process. In addition, the oil wax will melt and flow due to heat, and then re-solidify in places far from the heat source, which will further increase the severity of the blockage inside the tubing, thereby reducing the efficiency of wax removal. Furthermore, the removed oil wax cannot be easily recycled and disposed of. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figures 1 to 4 As shown, this utility model provides an oil pipe dewaxing device, including: a dewaxing ring 2, the dewaxing ring 2 is fixedly connected to one end of a heat-conducting ring 3 through a main positioning ring 12, and the other end of the heat-conducting ring 3 is fixedly connected to a base ring 6 through a secondary positioning ring 13, and a heating groove is opened in the heat-conducting ring 3, a heating component 5 is fixedly connected in the heating groove, and a wax separating mesh 4 is fixedly connected in the inner cavity of the heat-conducting ring 3. At the same time, the dewaxing ring 2, the heat-conducting ring 3 and the base ring 6 are all slidably connected in the inner cavity of the oil pipe body 1, and a fixing rod 7 is symmetrically connected to the end face of the base ring 6. A collecting plate 8 is fixedly connected to the side of the fixing rod 7, a fixing plate 9 is fixedly connected to the end face of the fixing rod 7, and a push rod 11 is fixedly connected to the surface of the fixing plate 9 through a transition plate 10.

[0019] In this embodiment, after the disassembled oil pipe body 1 is placed properly, the worker inserts the wax removal ring 2 and the heat-conducting ring 3 of the wax removal device into one end of the oil pipe body 1, and turns on the switch of the heating component 5. The heat generated by the heating component 5 is transferred to the wax removal ring 2 and the wax separating mesh 4 respectively. At this time, the worker can either manually push the wax removal device further into the oil pipe body 1 by pushing the push rod 11, or fix the connector at the end of the push rod 11 to an external power source, so that the external power source can push the wax removal device to move by pushing the push rod 11. During the process, the sharp end of the wax removal ring 2 can easily and conveniently separate the wax from the inner side of the oil pipe body 1 under the clamping of heat. The separated wax cannot move due to the obstruction of the unseparated wax, and will then be further separated by the subsequent wax separating mesh 4. The separated wax can then be stacked in small pieces on the surface of the collection plate 8. When the wax removal ring 2 passes through the other end of the oil pipe body 1, the oil pipe body 1 has completed the wax removal process. This not only effectively reduces the actual energy consumption of the device, but also improves the wax removal efficiency, and can also collect the cleaned wax for subsequent recycling.

[0020] As a preferred embodiment, the wax removal ring 2 has a cylindrical structure, the outer diameter of the wax removal ring 2 is matched with the inner diameter of the oil pipe body 1, and the inner cavity of the wax removal ring 2 has a frustum-shaped structure. At the same time, the main positioning groove opened on the end face of the wax removal ring 2 has a circular structure.

[0021] In this embodiment, as Figure 1and Figure 4 The dimensions of the outer surface of the wax removal ring 2 are matched with the dimensions of the inner cavity of the oil pipe body 1, which can help enhance the heat-cutting effect of the wax removal ring 2 on the oil wax accumulated in the inner cavity of the oil pipe body 1. At the same time, the inclined structure of the inner cavity of the wax removal ring 2 also facilitates the secondary division of the separated oil wax by the wax separating mesh 4, reducing the probability that the separated oil wax will hinder the movement of the wax removal device.

[0022] In a preferred embodiment, the heat-conducting ring 3 has a cylindrical structure. The main positioning ring 12 and the auxiliary positioning ring 13, which are fixedly connected to the end faces of the two ends of the heat-conducting ring 3, are both annular structures. The arc surfaces of the main positioning ring 12 and the auxiliary positioning ring 13 are provided with multiple sets of screw holes at equal intervals. At the same time, the dimensions of the main positioning ring 12 and the main positioning groove are compatible.

[0023] In this embodiment, as Figure 1 and Figure 4 The main positioning ring 12 is made of thermally conductive material, while the secondary positioning ring 13 is made of thermally insulating material. The main positioning ring 12 and the secondary positioning ring 13 are respectively adapted to the size of the main positioning groove and the secondary positioning groove, which can help enhance the stability of the fixed connection between the wax removal ring 2, the thermally conductive ring 3 and the base ring 6.

[0024] In a preferred embodiment, the wax separating mesh 4, which is fixedly connected to the inner cavity of the heat-conducting ring 3, has an overall circular structure, while the mesh of the wax separating mesh 4 has a square structure. The main positioning ring 12 and the secondary positioning ring 13 are fixedly connected to the wax removal ring 2 and the base ring 6 respectively by bolts. At the same time, the outer diameters of the wax removal ring 2, the heat-conducting ring 3 and the base ring 6 are all equal.

[0025] In this embodiment, as Figure 2 , Figure 3 and Figure 4 The wax removal ring 2, the heat conduction ring 3, and the wax separation mesh 4 are all made of heat-conducting material. The heating component 5 fixedly connected inside the heat conduction ring 3 can be a common heating product with constant temperature function on the market. Meanwhile, the base ring 6 is made of heat-insulating material, and the outer arc surface of the base ring 6 is symmetrically opened with wiring grooves to facilitate the power supply and control of the heating component 5.

[0026] In a preferred embodiment, the base ring 6 has a circular ring structure. A secondary positioning groove is opened on one end face of the base ring 6 relative to the position of the secondary positioning ring 13. Four sets of fixing rods 7 are fixedly connected around the other end face of the base ring 6 at equal intervals in the circumferential direction. At the same time, the four sets of fixing rods 7 are all long strip structures, and the end face of the fixing rods 7 is a square structure.

[0027] In this embodiment, as Figure 1 and Figure 2The setting of the fixing rod 7 enables the wax removal device to easily push the wax removal ring 2, heat conduction ring 3, wax distribution mesh 4 and base ring 6 inside the oil pipe body 1 through the cooperation of the push rod 11, transition plate 10 and fixing plate 9, thereby improving the convenience of using the wax removal device.

[0028] As a preferred embodiment, there are two sets of collecting plates 8. Both sets of collecting plates 8 are rectangular in shape, and the end face of the collecting plates 8 is a fan-shaped annular structure. A set of fixing rods 7 are fixedly connected to each end of the collecting plates 8. The cross-section formed by the combination of the collecting plates 8 and the fixing rods 7 is a semi-circular annular structure.

[0029] In this embodiment, as Figure 1 and Figure 2 The collection plate 8 can be made of lightweight plastic, which can help reduce the overall weight of the wax removal device. The two sets of collection plates 8 are fixedly connected to three adjacent sets of fixing rods 7, which can not only enhance the fixing effect of the fixing rods 7 on the base ring 6 and fixing plate 9, but also enhance the collection effect of the wax removal device on the cleaned wax, which is convenient for subsequent recycling.

[0030] In a preferred embodiment, the fixing plate 9 has a circular structure, the diameter of the fixing plate 9 is compatible with the outer diameter of the base ring 6, and the transition plate 10 fixedly connected to the surface of the fixing plate 9 has a frustum-shaped structure, while the weight-reducing groove opened in the fixing plate 9 has a hemispherical structure. At the same time, the push rod 11 fixedly connected to the transition plate 10 has a cylindrical structure, and the surface of the push rod 11 is uniformly opened with anti-slip stripes.

[0031] In this embodiment, as Figure 1 The structure of the transition plate 10 helps to enhance the uniformity of force on the fixed plate 9 and the fixed rod 7, reducing the probability of deformation and damage in the middle of the fixed plate 9. At the same time, the opening of the weight reduction groove can help reduce the weight of the transition plate 10. The connector at the end of the push rod 11 enables the wax removal device to be connected to an external power source to achieve automatic movement, enhancing the practicality of the wax removal device.
