Description

[0002] After the produced fluid from the oil well is transported to the combined station, it needs to be separated into oil, gas, water, and sediment impurities according to process requirements. Commonly used equipment includes three-stage separators, free water separators, and electrostatic dehydrators. The commonly used separation packing materials for these devices include stainless steel corrugated coalescing packing and ceramic packing.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] It should be noted that the terms "first," "second," etc., used in this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of this application described herein. In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," "horizontal," "lateral," "longitudinal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

[0034] This invention provides an airfoil plate module for an oilfield separator, used for oil, gas and water separation of produced fluids from oilfields, reducing the adhesion of crude oil and impurities, controlling the weight of a single module, enabling on-site assembly, and at a low cost.

[0035] like Figure 1 As shown, an airfoil module for an oilfield separator includes an airfoil component 1 and a process component 2. The airfoil structure reduces the adhesion of crude oil and impurities.

[0036] The airfoil component 1 includes a first airfoil assembly 3 and a second airfoil assembly 4. One end of the first airfoil assembly 3 is connected to one end of the second airfoil assembly 4. The first airfoil assembly 3 and the second airfoil assembly 4 are set at a certain angle to the horizontal plane. The process component 2 is used to fix the airfoil component 1 inside the oilfield separator.

[0037] The first airfoil assembly 3 and the second airfoil assembly 4 are at a certain angle to the horizontal plane to ensure optimal flowability of crude oil and impurities. After passing through the first airfoil assembly 3 and the second airfoil assembly 4, the attached crude oil and impurities will flow down the slope, increasing the service life of the airfoil component 1. The service life of the core airfoil component 1 is increased by 300%, reducing the annual cleaning frequency of the container equipment. The operating and maintenance costs of the separation and dehydration equipment are reduced.

[0038] like Figure 2 As shown, in one embodiment, the process component 2 includes a first bottom frame 5, a second bottom frame 6, a support column 7, an upper frame 8, and a support assembly.

[0039] The first end of the first bottom frame 5 and the first end of the second bottom frame 6 are respectively fixedly connected to the two sides of the bottom of the support column 7, and the upper frame 8 is fixedly installed on the upper part of the support column 7.

[0040] The first bottom frame 5, the second bottom frame 6, the supporting column 7, and the upper frame 8 form the outer frame of the airfoil module, ensuring the rigidity and stability of the airfoil module.

[0041] The first airfoil assembly 3 is disposed on the first bottom frame 5. The first airfoil assembly 3 includes n layers of first airfoils, where n is a positive integer greater than 1. The n layers of first airfoils are stacked sequentially from bottom to top on the first bottom frame 5. Multiple first spacers are disposed between adjacent layers of first airfoils in the n layers of first airfoils. During installation, the multiple first spacers are fixed on several first support rods 9 and several second support rods 10.

[0042] The second airfoil assembly 4 is mounted on the second bottom frame 6. The second airfoil assembly 4 includes m layers of second airfoils, where m is a positive integer greater than 1. The m layers of second airfoils are stacked sequentially from bottom to top on the second bottom frame 6. Multiple second spacers are provided between adjacent layers of second airfoils in the m layers. During installation, the multiple second spacers are fixed on several third support rods 11 and several fourth support rods 12.

[0043] like Figure 3 As shown, the support assembly includes several first support rods 9, several second support rods 10, several third support rods 11, and several fourth support rods 12. The first bottom frame 5 is connected to the first side of the upper frame 8 near its second end via several first support rods 9, and the middle of the first bottom frame 5 is connected to the support column 7 via several second support rods 10. The second bottom frame 6 is connected to the second side of the upper frame 8 near its second end via several third support rods 11, and the middle of the second bottom frame 6 is connected to the support column 7 via several fourth support rods 12.

[0044] In one embodiment, the first and second spacers are made of plastic, such as PPR. The use of plastic for the spacers makes the airfoil component 1 lightweight, easy to install, and the plastic material has good corrosion resistance and low cost.

[0045] In one embodiment, a plurality of first support rods 9 and a plurality of second support rods 10 are parallel to each other, the plurality of first support rods 9 are equally spaced, the plurality of second support rods 10 are equally spaced, and the plurality of first support rods 9 and the plurality of second support rods 10 are perpendicular to the first bottom frame 5; a plurality of third support rods 11 and a plurality of fourth support rods 12 are parallel to each other, the plurality of third support rods 11 are equally spaced, the plurality of fourth support rods 12 are equally spaced, and the plurality of third support rods 11 and the plurality of fourth support rods 12 are perpendicular to the second bottom frame 6.

[0046] In one embodiment, the upper frame 8 is perpendicular to the supporting column 7.

[0047] In one embodiment, the airfoil module is used for an oilfield separator with a cylindrical shell. The first airfoil assembly 3 and the second airfoil assembly 4 are mirror images of each other, i.e., m = n. The first bottom frame 5 and the second bottom frame 6 are mirror images of each other on both sides of the supporting column 7. The first bottom frame 5 is parallel to the n-layer first airfoil, and the second bottom frame 6 is parallel to the m-layer second airfoil.

[0048] The side of the first airfoil assembly 3 supporting the column 7 away from the supporting column 7 is a first arc shape, and the side of the second airfoil assembly 4 supporting the column 7 away from the supporting column 7 is a second arc shape. The radii of the first arc shape and the second arc shape are smaller than the inner circle radius of the shell. The first arc shape and the second arc shape can be set to the same size.

[0049] The dimensions of the first airfoil assembly 3, the second airfoil assembly 4, and the process component 2 are set according to the inner diameter of the shell. Specifically, the length of the support column 7 is less than the inner diameter of the shell, the center line of the support column 7 passes through the center of the shell, the second end of the first bottom frame 5 and the second end of the second bottom frame 6 have gaps with the inner wall of the shell, the side of the first airfoil assembly 3 away from the support column 7 has a gap with the inner wall of the shell, and the side of the second airfoil assembly 4 away from the support column 7 has a gap with the inner wall of the shell.

[0050] In one embodiment, the first and second wing plates are made of PPR material, also known as random copolymer polypropylene. PPR products have good toughness, high strength, excellent processing performance, good creep resistance at higher temperatures, and the unique advantage of high transparency of random copolymer polypropylene.

[0051] It should be noted that in order to reduce the overall weight of the airfoil module, the sheet material should be as thin as possible; at the same time, to ensure the rigidity of the entire airfoil module, the sheet material should be as thick as possible. Preferably, the thickness of the first airfoil and the second airfoil is between 3.5 and 4.0 mm.

[0052] like Figure 2 As shown, further, a first steel plate layer 31 is provided in the middle of the n-layer first wing plate, and a second steel plate layer 41 is provided in the middle of the m-layer second wing plate. Steel plate layers are provided in the middle of the multi-layer first wing plate and the multi-layer second wing plate respectively, which plays the role of overall strengthening of the first wing plate assembly 3 and the second wing plate assembly 4.

[0053] The first and second wing plates in this embodiment of the invention are made of specified non-metallic materials, which are lighter in weight compared to conventional carbon steel and stainless steel fillers, reducing the weight of a single wing plate module and facilitating on-site installation. Furthermore, the materials selected for the first and second wing plates have good corrosion resistance, eliminating the need for secondary corrosion protection.

[0054] like Figure 3As shown, in one embodiment, the airfoil module for the oilfield separator further includes a first connecting component 13, a second connecting component 14, a third connecting component 15, a fourth connecting component 16, a first connecting plate 17, and a second connecting plate 18. The connecting components and connecting plates are used for connecting the airfoil module to the equipment to be modified.

[0055] The first connecting component 13 is located near the bottom of the second end of the first bottom frame 5, and the second connecting component 14 is located at the bottom of the middle position of the first bottom frame 5; the third connecting component 15 is located near the bottom of the second end of the second bottom frame 6, and the fourth connecting component 16 is located at the bottom of the middle position of the second bottom frame 6; the first connecting plate 17 and the second connecting plate 18 are respectively located on both sides of the upper frame 8.

[0056] For example, if the airfoil module is used for an oilfield separator with a cylindrical shell, the first connecting component 13 and the second connecting component 14 are used to connect the first bottom frame 5 to the shell, the third connecting component 15 and the fourth connecting component 16 are used to connect the second bottom frame 6 to the shell, and the first connecting plate 17 and the second connecting plate 18 are used to connect the upper frame 8 to the shell.

[0057] Furthermore, the first connecting component 13 and the third connecting component 15 are mirror images of each other with the center line of the supporting column 7 as the center, the second connecting component 14 and the fourth connecting component 16 are mirror images of each other with the center line of the supporting column 7 as the center, and the first connecting plate 17 and the second connecting plate 18 are mirror images of each other with the center line of the supporting column 7 as the center.

[0058] Specifically, both the first connecting component 13 and the third connecting component 15 include a first support rod 19 and a first arc plate 20. One end of the first support rod 19 of the first connecting component 13 is connected to the bottom of the second end of the first bottom frame 5, and the other end of the first support rod 19 of the first connecting component 13 is connected to the first arc plate 20.

[0059] Both the second connecting assembly 14 and the fourth connecting assembly 16 include a second support rod 21 and a second arc plate 22. One end of the second support rod 21 of the second connecting assembly 14 is connected to the bottom of the first bottom frame 5 at the middle position, and the other end of the second support rod 21 of the second connecting assembly 14 is connected to the second arc plate 22.

[0060] The radii of the first arc plate 20, the second arc plate 22, the first connecting plate 17, and the second connecting plate 18 are the same as the radius of the inner circle of the shell, so that the first arc plate 20, the second arc plate 22, the first connecting plate 17, and the second connecting plate 18 fit snugly against the shell, which facilitates installation, fixation, and aesthetics.

[0061] In one embodiment, the first bottom frame 5 and the second bottom frame 6 are welded from channel steel, the supporting column 7 and the upper frame 8 are welded from channel steel, the supporting components are all made of seamless steel pipes, the first arc plate 20, the second arc plate 22, the first connecting plate 17 and the second connecting plate 18 are made of Q235B steel plates, and the use of commonly used profiles and pipes makes the cost of the airfoil module low.

[0062] The airfoil module of this invention can be used in three-phase separators, free water extractors, and electrostatic dehydrators with a diameter ≤ 4000mm. The following example uses a three-phase separator with a diameter of 4000mm as an example for illustrative description.

[0063] The angle between the first airfoil assembly 3 and the horizontal plane and the angle between the second airfoil assembly 4 and the horizontal plane are both 35°. The first airfoil assembly 3 includes 39 layers of first airfoils, and the second airfoil assembly includes 39 layers of second airfoils. Four first support rods 9 are provided (two sets of two rods each on both sides of the first bottom frame 5), six second support rods 10 are provided (two sets of three rods each on both sides of the first bottom frame 5), four third support rods 11 are provided (two sets of two rods each on both sides of the second bottom frame 6), and four fourth support rods 1... 2. Six supports are provided (two sets of three supports are provided on both sides of the second bottom frame 6). The first support rod 9 and the second support rod 10 are perpendicular to the first bottom frame 5. The third support rod 11 and the fourth support rod 12 are perpendicular to the second bottom frame 6. The gap between the first airfoil assembly 3 and the shell is 50mm on the side away from the support column 7. The gap between the second airfoil assembly 4 and the shell is also 50mm on the side away from the support column 7. The first arc plate 20, the second arc plate 22, the first connecting plate 17 and the second connecting plate 18 are respectively attached to the inner sidewall of the shell.

[0064] The airfoil module of this invention adopts a standardized design. The width of the airfoil module can be set to a fixed value. For example, the width of the airfoil module can be set to one meter. According to the capacity requirements of the separation equipment, multiple airfoil modules are combined into a packing. If it is used for a three-phase separator, free water extractor, or electrostatic dehydrator with a diameter of 4000mm, four sets of airfoil modules are set as a group for use under normal circumstances.

[0065] like Figure 4 As shown, this embodiment of the invention also provides an installation method for the airfoil module used in the oilfield separator 24, comprising: using seamless pipe and channel steel to weld a bracket 23; placing the airfoil component 1 on the bracket 23; using a chain hoist to transfer the bracket 23 together with the airfoil component 1 to a designated position inside the oilfield separator 24; using a jack to lift the airfoil component 1; using a process component 2 to fix the airfoil component 1 inside the oilfield separator 24; removing the bracket 23; and welding the process component 2 to the connection point inside the oilfield separator 24.

It has high and stable separation and dehydration efficiency, reduced operation and maintenance costs of separation and dehydration equipment, reduced weight of individual components, and facilitates on-site installation.
