Description

Technical Field

[0001] The utility model belongs to the technical field of offshore petroleum engineering, and in particular relates to a combined supporting device for an underwater multiphase flow meter. Background Art

[0002] At present, underwater multiphase flowmeters have the function of measuring the oil, gas and water produced at underwater wellheads. They are key equipment for measuring logistics at a single underwater wellhead and are usually installed on production facilities such as underwater manifolds. However, they have a complex structure, large size and weight, and the fluid needs to flow through the flowmeter body in a bottom-in and top-out manner to ensure the accuracy of the measurement. This leads to a large height difference between the inlet pipeline and the outlet pipeline of the underwater multiphase flowmeter. In addition, when the flowmeter and its inlet and outlet pipelines are used underwater for a long time, they must not only withstand the displacement caused by the temperature change of the fluid inside the pipeline, but also withstand the effects of external loads such as ocean currents. Therefore, their support and fixing methods have high requirements. The existing support method of underwater multiphase flowmeters cannot solve the support and limit problems of underwater multiphase flowmeters, and thus cannot ensure the long-term stable operation and use of underwater multiphase flowmeters underwater.

[0003] Therefore, it is urgent to design a combined support device for an underwater multiphase flowmeter to solve the above-mentioned support and limit problems of the underwater multiphase flowmeter. Utility Model Content

[0010] Furthermore, the first half ring is symmetrically fixedly connected to two opposite sides with a first flange plate, and the second half ring is symmetrically fixedly connected to two opposite sides with a second flange plate. By fixing the first flange plate and the second flange plate, the first half ring and the second half ring are spliced ​​into a clamping ring.

[0024] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0025] Those skilled in the art will appreciate that, although some embodiments herein include certain features included in other embodiments but not other features, the combination of features of different embodiments is meant to be within the scope of the present invention and form different embodiments. For example, in the claims, any one of the claimed embodiments may be used in any combination.

[0026] Please refer to the attached Figure 1 To Attachment Figure 5 The utility model describes a combined supporting device for an underwater multiphase flow meter.

[0027] There is a large height difference between the inlet pipeline 5 of the underwater multiphase flowmeter 4 and the outlet pipeline 6 of the underwater multiphase flowmeter 4. When the underwater multiphase flowmeter 4 and its inlet and outlet pipelines are used underwater for a long time, they must not only withstand the displacement caused by the temperature change of the fluid inside the pipeline, but also withstand the effects of external loads such as ocean currents. The existing support method for the underwater multiphase flowmeter 4 cannot solve the problem of supporting and limiting the underwater multiphase flowmeter 4.

[0028] Therefore, the utility model provides a combined support device for an underwater multiphase flowmeter, such as Figure 1 and Figure 2 As shown, it includes: an anti-sinking plate foundation 1, a supporting steel 2 is fixedly connected to the anti-sinking plate foundation 1, and a supporting plate 7 is fixedly connected to the end of the supporting steel 2 away from the anti-sinking plate foundation 1 to support the inlet pipeline 5 of the underwater multiphase flowmeter 4. A limiting plate 8 is provided on the supporting plate 7 to radially limit the inlet pipeline 5 of the underwater multiphase flowmeter 4. Specifically, the limiting plates 8 are symmetrically arranged, and an accommodating cavity for accommodating the inlet pipeline 5 is reserved between the limiting plates 8. The accommodating cavity matches the inlet pipeline 5, and the accommodating cavity radially limits the inlet pipeline 5. An outlet pipeline support 3 is fixedly connected to the anti-sinking plate foundation 1 to support and radially limit the outlet pipeline 6 of the underwater multiphase flowmeter 4. The inlet pipeline 5 is supported and radially limited by the supporting steel 2 and the limiting plate 8, and the outlet pipeline 6 is supported and radially limited by the outlet pipeline support 3, so as to achieve the purpose of combined support of the underwater multiphase flowmeter 4, thereby ensuring the reliability of support and limitation of the underwater multiphase flowmeter 4.

[0029] A lower rib plate 9 is fixedly connected between the support steel 2 and the support plate 7 to ensure that the structural rigidity between the support steel 2 and the support plate 7 meets the support limit requirements, and an upper rib plate 10 is fixedly connected between the support plate 7 and the limit plate 8 to ensure that the structural rigidity between the support plate 7 and the limit plate 8 meets the support limit requirements.

Specifically, after the clamping ring 33 clamps the outlet pipeline 6, the outlet pipeline 6 is limited by the clamping ring 33, and the clamping ring 33 generates friction with the outlet pipeline 6 due to the tightening pressure, thereby supporting the outlet pipeline 6 through the friction force.

[0031] A second diagonal brace 32 is fixedly connected to the anti-sinking plate foundation 1 , and one end of the second diagonal brace 32 away from the anti-sinking plate foundation 1 is fixedly connected to the first diagonal brace 31 to support the first diagonal brace 31 and improve the structural strength of the second diagonal brace 32 .

[0032] Preferably, the second diagonal brace 32 is in the same plane as the first diagonal brace 31 and the clamping ring 33, the second diagonal brace 32 is fixedly connected to the middle section of the first diagonal brace 31, and the second diagonal brace 32 is arranged at an angle to the first diagonal brace 31. While forming a stable supporting structure, the outlet pipeline 6 of the underwater multiphase flowmeter 4 is avoided so that the second diagonal brace 32 and the outlet pipeline 6 of the underwater multiphase flowmeter 4 do not interfere with each other. Optionally, the angle between the first diagonal brace 31 and the second diagonal brace 32 is 60 degrees.

[0033] like Figure 4 and Figure 5 As shown, the clamping ring 33 includes a first half ring 331 and a second half ring 332. The first half ring 331 is fixedly connected to the first diagonal support 31. One end of the first half ring 331 away from the first diagonal support 31 is detachably connected to the second half ring 332. The first half ring 331 and the second half ring 332 can be spliced ​​to form the clamping ring 33.

[0037] A first rib plate 335 is fixedly connected between the first half ring 331 and the first flange plate 333 to strengthen the structural rigidity between the first half ring 331 and the first flange plate 333 , and a second rib plate 336 is fixedly connected between the second half ring 332 and the second flange plate 334 to strengthen the structural rigidity between the second half ring 332 and the second flange plate 334 .

[0038] The inner walls of the first half ring 331 and the second half ring 332 are both provided with a rubber layer 337. The first half ring 331 and the second half ring 332 are in contact with the outlet pipeline 6 of the underwater multiphase flowmeter 4 through the rubber layer 337 to provide buffering protection for the outlet pipeline 6 and avoid deformation of the outlet pipeline 6, and to strengthen the friction between the outlet pipeline 6 and the clamping ring 33 to make the support more reliable.

[0039] Preferably, the rubber layer 337 is made of a 10 mm thick neoprene rubber plate, and bolts are passed through the through holes of the first flange plate 333 and the through holes of the second flange plate 334 and are screwed and fastened with double nuts. After fastening, the distance between the first flange plate 333 and the second flange plate 334 is 10 mm.

After tightening, the spacing between the first flange plate 333 and the second flange plate 334 is 10 mm.

[0041] The working principle of the utility model is as follows: first, the supporting steel 2 is welded to the anti-sinking plate foundation 1, and then the underwater multiphase flowmeter 4 is installed, and the inlet pipeline 5 of the underwater multiphase flowmeter 4 is installed in the accommodating cavity formed by the limiting plate 8, and then the outlet pipeline support 3 is welded to the anti-sinking plate foundation 1 according to the position of the underwater multiphase flowmeter 4, and finally the outlet pipeline 6 between the first half ring 331 and the second half ring 332 is fixed to complete the installation of the outlet pipeline support 3.
