Description

Technical Field

[0001] The utility model belongs to the technical field of anti-scaling, descaling and anti-wax equipment for oilfield gathering and transportation pipelines, and specifically relates to a ball-through type multi-element alloy physical anti-scaling, anti-corrosion and anti-wax device. Background Art

[0002] Scaling and waxing are one of the most serious problems encountered in oil fields. They usually occur in gathering and transportation pipelines, water injection pipelines and the inner surface of equipment, such as oil well pipelines, high water content crude oil gathering and transportation systems, sewage station filter tanks, heating furnace bodies, and mixed injection systems of headers and groundwater. Scaling and waxing bring many hazards to production, such as causing increased water injection pressure and reduced oil well production, blocking pipelines and local corrosion, increased energy consumption and reduced heat transfer rate, increased cleaning time and shutdown time for maintenance, etc., and serious safety accidents may occur. The utility model patent with publication number CN221400433U and patent name "Integrated scale inhibition device for oil wells" is essentially a device for treating scale inhibition by chemical methods. The previous physical anti-scaling, anti-corrosion and anti-wax multi-element alloy chips were porous thin sheets. Multiple pieces were combined into a device and installed at the required position to achieve the purpose of anti-scaling, anti-corrosion and anti-wax. However, due to the special process requirements of the oil field, the pipeline needs to be passed through the ball. Since the holes in the alloy chips are generally small (φ4mm-10mm), the ball cannot be passed through, which limits the application of such devices. In addition, the oil well may contain large particles or long flocs, which will also block the holes in the alloy chips. Utility Model Content

[0004] In order to solve the above-mentioned technical problems, the utility model discloses a through-ball type multi-element alloy physical anti-scale, anti-corrosion and anti-wax device, comprising an outer cylinder, the upper end of the outer cylinder is connected to a porous connector, a porous anti-scale alloy body is arranged in the outer cylinder, and the porous anti-scale alloy body is installed between the lower end of the porous connector and the bottom of the outer cylinder; a connected channel is formed at the center of the porous connector, the porous anti-scale alloy body and the outer cylinder, a plurality of inclined holes communicating with the channel are arranged on the side of the porous connector, horizontal holes are arranged in the alloy chip on the outer wall of the porous anti-scale alloy body, and through holes are arranged on the outer wall of the porous anti-scale alloy body.

[0005] The technical solution of the utility model also has the following characteristics:

[0006] As a further improvement of the technical solution of the utility model, the upper end of the porous connector is connected to an upper flange, and the lower end of the outer cylinder is connected to a lower flange.

[0007] As a further improvement of the technical solution of the utility model, the lower end of the porous connector is threadedly assembled with the upper end of the outer cylinder.

[0014] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0015] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0016] Example 1

[0017] like Figure 1As shown, the utility model is a ball-through type multi-element alloy physical anti-scaling, anti-corrosion and anti-wax device, including an outer cylinder 4, the upper end of which is connected to a porous connector 2, a porous anti-scaling alloy body 3 is arranged inside the outer cylinder 4, and the porous anti-scaling alloy body 3 is installed between the lower end of the porous connector 2 and the bottom of the outer cylinder 4.

[0018] A connected channel 9 is formed at the center of the porous interconnector 2, the porous anti-scaling alloy body 3 and the outer tube 4, a plurality of inclined holes 8 communicating with the channel 9 are arranged on the side of the porous interconnector 2, a plurality of horizontal holes 11 are arranged in the plurality of alloy chips 7 on the outer wall of the porous anti-scaling alloy body 3, and a plurality of through holes 10 are arranged on the outer wall of the porous anti-scaling alloy body 3.

[0019] The outer cylinder 4 of different sizes is selected according to the diameter of the gathering and transportation pipeline, and the ball-through type multi-element alloy physical anti-scaling, anti-corrosion and anti-wax device of the utility model is installed at any position requiring anti-scaling, anti-corrosion and anti-wax.

[0020] During assembly, first place the porous anti-scaling alloy body 3 in the outer tube 4, and then firmly connect the porous connector 2 to the outer tube 4, so that the porous anti-scaling alloy body 3 and the alloy chip 7 on the outer wall are fixed inside the outer tube 4, and then the assembly is completed after leveling, rust removal and painting, and then it is installed at any part of the gathering and transportation pipeline as required to play its role.

[0021] The porous anti-scaling alloy body 3 and the alloy chip 7 on its outer wall use physical methods to achieve scale inhibition and scaling prevention. Select a variety of metal elements with different electronegativity, through a unique alloy composition design and strict smelting preparation control. Countless non-soluble uniform micro-battery systems are formed in the alloy microstructure, and solid-liquid-electron interactions occur during the full contact with the fluid, thereby adjusting the physical properties of the fluid, affecting the nucleation and growth process of scaling crystals, changing the adhesion and dispersion properties of scaling, and achieving excellent anti-scaling performance; at the same time, after the alloy contacts the fluid, the changes in physical parameters such as surface tension, viscosity, and potential cause the old scale that has been generated to dissolve; and greatly reduce the occurrence of under-scale corrosion (such as alkali corrosion, acid corrosion, etc.), thereby playing an anti-corrosion role.

[0022] When working, the liquid enters from the porous connector 2, and flows out from the inner channel 9 and the inclined hole 8 thereof respectively. The liquid flowing out from the channel 9 enters the channel 9 in the porous anti-scaling alloy body 3, and the liquid flowing out from the inclined hole 8 finally enters the channel 9 in the porous anti-scaling alloy body 3 through the hole 10, and the liquid is finally discharged from the channel 9 of the outer cylinder 4. When the liquid flows through the porous anti-scaling alloy body 3 and the alloy chip 7 on its outer wall, it will be fully contacted, and the electrochemical reaction can ensure that the liquid flows out smoothly, and the impurities in it are not easy to form deposits on the inner wall, so as to achieve the purpose of physical anti-scaling, anti-corrosion and anti-wax. When it is necessary to throw a ball, the ball can be thrown in from the inlet, and the inner diameter of the channel 9 matches the ball, which can ensure that the ball passes smoothly.

[0023] Example 2

[0025] The ball-through type multi-element alloy physical anti-scaling, anti-corrosion and anti-wax device of the utility model can be installed in a gathering and transportation pipeline through the upper flange 1 and the lower flange 5 .

[0026] Example 3

[0027] like Figure 1 As shown, unlike Example 2, in Example 3, a ball-through type multi-element alloy physical anti-scaling, anti-corrosion and anti-wax device of the utility model, the lower end of the porous connector 2 is threadedly assembled with the upper end of the outer tube 4, which is convenient for assembly and disassembly and is easy to remove later.

[0030] After the two ends of the porous anti-scaling alloy body 3 are respectively inserted into the two installation grooves, the positioning can be completed, ensuring that it is stably assembled and is not prone to shaking during operation.

[0031] Example 5

[0033] The sealing gasket 6 can play a buffering role on the one hand to prevent the two ends of the porous anti-scaling alloy body 3 from being damaged due to hard contact after being respectively inserted into the two installation grooves, and can also play a sealing role to prevent liquid from leaking out.
