Description

Technical Field

[0001] The utility model belongs to the technical field of oilfield gathering pipelines. Specifically, it relates to a device for centralized scale removal of gathering pipelines. Background Technique

[0002] Oilfield gathering pipelines are pipeline systems that transport the crude oil produced in the oilfield to processing facilities or end-users through pipelines. These pipelines are usually a crucial part of oilfield development and are used to transport crude oil from the production site to processing plants, storage facilities, or export ports. Scaling is usually caused by the deposition and solidification of sediments inside the pipelines, mainly including substances such as calcium and magnesium salts, sulfides, and oils. The main method for preventing scaling problems in gathering pipelines is as follows: 1. Add scale inhibitors at selected positions in the gathering pipelines to prevent scaling; 2. Conduct hot washing operations on the scaled pipelines.

[0003] Upon inspection, the publication number: CN206199808U discloses a device for centralized scale removal of gathering pipelines. In this technology, it is disclosed that "including: a box body, the box body is a cuboid, the left side of the box body is flange-connected to the inlet gathering pipe, the right side of the box body is flange-connected to the outlet gathering pipe, and the top of the box body is fixedly connected with a plurality of flange plates communicating with the inside of the box body; a metal screen, the metal screen is fixedly connected to one side of the box body close to the inlet gathering pipe; flange heating pipes, the number of flange heating pipes is equal to the number of flange plates. The flange heating pipe includes a connecting flange, a heating pipe, and a metal screen cylinder. The heating pipe and the metal screen cylinder are fixedly connected below the connecting flange. The metal screen cylinder is sleeved outside the heating pipe. The heating pipe in the flange heating pipe extends into the box body and is fixedly connected to the flange plate through the connecting flange; a corrugated plate. The utility model uses a variety of methods to achieve the purpose of scale removal, and the effect is prominent.";

[0004] However, in the above-mentioned comparative document, the metal screen cylinder will be blocked on the filter holes by dirt after long-term use, which is not conducive to the flow of oilfield fluids. Since the fluid scales, it is necessary to regularly clean the dirt to avoid excessive dirt deposition. During the use of the scale treatment pipe, it may not be convenient to install the scaled pipe on the oilfield gathering pipeline, thus making it inconvenient to clean the dirt inside the scaled pipe, which may significantly reduce the flow rate of the fluid. Secondly, since most oilfield gathering pipelines are used in outdoor environments, during the use of the scaled pipe, it may not be convenient to perform closed protection treatment on the scaled pipe, which may cause damage to heating elements and the like inside the scaled pipe;

[0005] Regarding the problems in the related technology, no effective solution has been proposed yet. Content of the Utility Model

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0029] Refer to Figures 1 - 3 , this embodiment provides a technical solution: a device for centralized scale removal of gathering and transportation pipelines, including a sleeve 1, a scale formation pipe 2 is detachably connected inside the sleeve 1, the scale formation pipe 2 is located in the middle area inside the sleeve 1, an installation component 3 for clamping and limiting the scale formation pipe 2 is arranged on the sleeve 1, and a support component 4 for supporting the sleeve 1 is arranged at the bottom of the sleeve 1;

[0030] The installation component 3 includes a lower limit plate 31 fixedly connected to the inner bottom wall of the sleeve 1. There are two lower limit plates 31, and the two lower limit plates 31 are symmetrically distributed with the central axis of the sleeve 1 as the center. The top of the sleeve 1 is detachably connected with a top plate 32. Both the lower limit plate 31 and the upper limit plate 33 are arc-shaped. A upper limit plate 33 is fixedly connected to the bottom of the top plate 32. There are two upper limit plates 33, and the two upper limit plates 33 are symmetrically distributed with the central axis of the top plate 32 as the center. The lower limit plate 31 and the upper limit plate 33 are respectively located above and below the scale formation pipe 2. A first installation groove 34 is opened on the top plate 32. There are four first installation grooves 34, and the four first installation grooves 34 are evenly distributed on the top of the top plate 32. A second installation groove 35 is opened on the top of the sleeve 1. There are four second installation grooves 35, and the four second installation grooves 35 are evenly distributed on the top of the sleeve 1, and the second installation groove 35 is communicated with the first installation groove 34. The top plate 32 is threadedly connected with a first self-tapping screw 37 through the first installation groove 34. The top plate 32 is detachably connected with an installation plate 36 through the first self-tapping screw 37. The first self-tapping screw 37 first threadedly penetrates the installation plate 36 and then is connected to the top plate 32. A second self-tapping screw 38 is threadedly connected inside the installation plate 36. The second self-tapping screw 38 first threadedly penetrates the installation plate 36 and then is connected to the sleeve 1. The second self-tapping screw 38 is threadedly connected with the sleeve 1. When the top plate 32 moves to the top of the sleeve 1, the installation plate 36 fits with the sleeve 1 and the top plate 32 through the first installation groove 34 and the second installation groove 35. The first self-tapping screw 37 and the second self-tapping screw 38 fix the installation plate 36, so that the top plate 32 closes the top of the sleeve 1. At this time, the scale formation pipe 2 is located between the upper limit plate 33 and the lower limit plate 31, thereby clamping and limiting the scale formation pipe 2, and further facilitating the installation and disassembly of the scale formation pipe 2.

[0031] Refer to Figure 2, a clamping groove 39 is formed at the top of the sleeve 1, and the clamping groove 39 is adapted to the top plate 32. The top plate 32 is attached to the sleeve 1 through the clamping groove 39, which facilitates the installation and use of the top plate 32.

[0032] Refer to Figure 1 , the support assembly 4 includes an arc-shaped support plate 41 fixedly connected to the outer side wall of the sleeve 1. The arc-shaped support plate 41 is arranged in an arc shape. There are two arc-shaped support plates 41, and the two arc-shaped support plates 41 are symmetrically distributed around the central axis of the sleeve 1. A vertical steel 42 is fixedly connected to the outer side wall of the arc-shaped support plate 41. There are four vertical steels 42, and the four vertical steels 42 are evenly distributed on the two arc-shaped support plates 41. The bottom of the vertical steel 42 is fixedly connected to a horizontal steel 43. The arc-shaped support plate 41, the vertical steel 42 and the horizontal steel 43 stably support the sleeve 1, and the arc-shaped support plate 41, the vertical steel 42 and the horizontal steel 43 are all assembled by welding.

[0033] Refer to Figure 1 , a square steel 44 is fixedly connected to the outer side of the top of the vertical steel 42. The square steel 44 is arranged horizontally, and the square steel 44 further increases the load-bearing capacity of the support assembly 4.

[0034] Refer to Figure 1 , Figure 2 and Figure 4 , both ends of the scaling pipe 2 are fixedly connected with two side diameter pipes 5. There are two side diameter pipes 5, and the two side diameter pipes 5 are symmetrically distributed around the central axis of the scaling pipe 2. One end of each of the two side diameter pipes 5 far from the scaling pipe 2 is connected to a sleeve 6 through a flange. One end of one sleeve 6 far from the side diameter pipe 5 is connected to an outlet gathering and transportation pipe 7 through a flange, and one end of the other sleeve 6 far from the side diameter pipe 5 is connected to an inlet gathering and transportation pipe 8 through a flange. The oilfield fluid flows and is transmitted through the inlet gathering and transportation pipe 8, the sleeve 6, the side diameter pipe 5, the scaling pipe 2 and the outlet gathering and transportation pipe 7.

[0035] Refer to Figure 4 , an auger 9 is fixedly connected to the inside of the inlet gathering and transportation pipe 8. The auger 9 slows down the flow rate of the fluid inside the inlet gathering and transportation pipe 8 and reduces the impact on the inside of the scaling pipe 2.

[0036] Refer to Figure 5 , a sleeve plate 10 is fixedly connected to the outer side wall of the side diameter pipe 5. The scaling pipe 2 and the sleeve plate 10 are coaxial. A heating pipe 11 is fixedly connected to the inside of the sleeve plate 10. The heating pipe 11 is arranged in a spiral shape inside the sleeve plate 10. The scaling pipe 2 is mainly made of copper material and has good thermal conductivity. After the heating pipe 11 operates, the fluid inside the scaling pipe 2 is heated.

[0037] Working principle: First, move the sleeve 1 to the appropriate connection of the gathering and transportation pipeline. The arc-shaped support plate 41, vertical steel 42, horizontal steel 43, and square steel 44 stably support the sleeve 1. The outlet gathering and transportation pipe 7 and the inlet gathering and transportation pipe 8 are respectively installed on the two sleeves 6 through flange plates. The oil flows through the inlet gathering and transportation pipe 8, sleeve 6, side diameter pipe 5, scaling pipe 2, and outlet gathering and transportation pipe 7. The heating pipe 11 operates to heat-treat the liquid oil flowing inside the scaling pipe 2. The auger 9 slows down the flow rate of the fluid, causing the fluid to scale intensively inside the scaling pipe 2. When it is necessary to clean the scale inside the scaling pipe 2, the second self-tapping screw 38 rotates and moves upward to separate from the sleeve 1. Subsequently, the top plate 32 moves upward to separate from the card slot 39 at the top of the sleeve 1, making the top of the sleeve 1 in an open state. The upper limit plate 33 and the lower limit plate 31 no longer firmly clamp the scaling pipe 2. Then, remove the flange plate bolted between the side diameter pipe 5 and the sleeve 6, and the scaling pipe 2 can be removed from the inside of the sleeve 1. Subsequently, the dirt inside the scaling pipe 2 can be flushed with a high-pressure water gun, facilitating the disassembly and cleaning of the scaling pipe 2.

[0038] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
