Description

Technical Field

[0001] The utility model relates to the technical field of oilfield exploitation, in particular to a water-mixing anti-clogging water nozzle. Background Art

[0002] Water injection is a process used in oil well production. By injecting water to carry heat, the first is to change the fluidity of crude oil, thereby reducing oil flow resistance and achieving the goal of smoothly transporting crude oil under stable back pressure conditions in the surface pipeline; the second is to reduce the viscosity of the wellbore by injecting water, thereby reducing the production load and avoiding the well from being left lying.

[0003] Under a certain pressure differential, the amount of water injection can be controlled by replacing and adjusting nozzles with different apertures. However, during the production process, due to factors such as excessive impurities in the water injection machinery and scaling and shedding in the transmission pipeline, the apertures of ordinary water injection nozzles are easily clogged, resulting in water injection interception or interruption. This prevents the normal heat transfer through the water injection, causing increased back pressure and even blockage in the crude oil transmission pipeline, and increased load, leading to the problem of lying wells. Utility Model Content

[0004] The utility model aims to provide a water mixing and clogging-proof water nozzle, so as to solve the problem that the existing water mixing nozzle is easily clogged, resulting in interception or interruption of water mixing.

[0014] Furthermore, the connecting section is provided with an external thread.

[0015] Furthermore, the water-injection anti-clogging nozzle is made of stainless steel.

[0016] Furthermore, the distance from the edge of the side water inlet hole closest to the end where the faucet cap is connected to the connecting section to the end where the faucet cap is connected to the connecting section is 1 mm.

[0017] Furthermore, the length of the connecting section is 15 mm, the diameter of the water outlet hole is 4.4 mm, and the length of the water outlet hole is 13 mm.

[0018] Based on the above technical solutions, the technical effects achieved by the present invention are:

[0026] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0027] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0028] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0029] The existing water injection nozzles have holes that are very easy to clog, causing water injection interception or interruption, resulting in the inability to transport heat normally through water injection, thereby causing the back pressure of the crude oil pipeline to increase or even clog, and the load to increase, resulting in the problem of lying wells.

[0030] In view of this, the utility model provides a water-injected and anti-clogging faucet, including a faucet cap 100 and a connecting section 200; a central water inlet hole 110 and multiple side water inlet holes 120 are provided on the faucet cap 100, and a water outlet hole 210 is provided on the connecting section 200; the central water inlet hole 110 is connected to the water outlet hole 210, and the side water inlet holes 120 are connected to the central water inlet hole 110 and connected to the water outlet hole 210 through the central water inlet hole 110.

[0031] The water-injection anti-clogging faucet provided by the present invention realizes multi-hole water inlet by providing a central water inlet hole 110 and multiple side water inlet holes 120, thereby avoiding throttling or clogging caused by obstruction of a single water inlet channel. By connecting the side water inlet holes 120 and the water outlet holes 210 through the central water inlet hole 110, the aperture of the channel flowing to the water outlet holes 210 is guaranteed to be consistent, that is, the aperture of the central water inlet hole 110 ensures the constancy of the delivery channel, avoids the multi-hole water inlet causing the water inlet diameter to become larger or the water inlet diameter to change after some water inlet holes are blocked, thereby ensuring the stability of the water injection amount and achieving the anti-clogging effect through the multi-inlet and single-outlet method.

[0032] The following combination Figure 1-Figure 3 The structure and shape of the water-injection anti-clogging faucet provided in this embodiment are described in detail:

[0033] In this embodiment, Figure 2 As shown, the faucet cap 100 is connected to the connecting section 200. The faucet cap 100 is configured as a polygonal prism structure, and the connecting section 200 is provided with external threads. The polygonal prism structure facilitates assembly and disassembly with a suitable wrench. In this embodiment, a hexagonal prism structure is used. The external threads are used to achieve a threaded connection with the faucet seat of the faucet assembly in the co-mixing production process. The faucet seat is installed in the faucet assembly through a threaded connection, thereby achieving the installation of a water-mixing and anti-clogging faucet.

[0034] In this embodiment, the axis of the polygonal prism is provided with a central water inlet hole 110, the central water inlet hole 110 and the water outlet hole 210 both extend along the axial direction of the faucet cap 100, and the side water inlet hole 120 extends along the radial direction of the faucet cap 100. Figure 1 、 Figure 3 As shown,

[0035] In this embodiment, the side water inlet holes 120 are arranged along the axial direction of the faucet cap 100, and each side surface of the polygonal prism is provided with a side water inlet hole 120. The arrangement of the side water inlet holes 120 along the axial direction of the faucet cap 100 allows the faucet cap 100 to have multiple water inlet holes in the axial direction, which can better prevent clogging compared to providing multiple water inlet holes on the same cross-section.

[0036] In this embodiment, one or more side water inlet holes 120 may be provided on each side surface of the polygonal prism. When multiple side water inlet holes 120 are provided, the multiple side water inlet holes 120 are arranged along the axial direction of the faucet cap 100 .

[0037] In this embodiment, multiple groups of side water inlet holes 120 can be provided, with each group of water inlet holes arranged around the axis of the faucet cap 100. Multiple groups of water inlet holes are arranged along the axial direction of the faucet cap 100. The more side water inlet holes 120 there are, the lower the chance of clogging. However, due to structural size limitations, processing cost limitations, and structural strength factors, in this embodiment, the number of side water inlet holes 120 in each group is set to one, which can meet the anti-clogging effect requirements.

[0038] In this embodiment, the diameter of the central water inlet hole 110 is equal to that of the side water inlet hole 120, and the diameter of the water outlet hole 210 is not less than that of the central water inlet hole 110. Figure 3 By limiting the diameters of the central water inlet hole 110, the side water inlet holes 120, and the water outlet holes 210, and by connecting the holes, the flow cross-section of the water is guaranteed to be constant when it finally enters the water outlet hole 210. That is, the diameter of the central water inlet hole 110 ensures the control of the water mixing parameters.

[0039] In this embodiment, the length of the center water inlet hole 110 is increased by 2mm from the length of the water faucet cap 100, the minimum distance from the edge of the side water inlet hole 120 to the end of the water faucet cap 100 connected to the connecting section 200 is 1mm, and the distance from the edge of at least one side water inlet hole 120 to the end of the water faucet cap 100 connected to the connecting section 200 is 1mm; the length of the connecting section 200 is 15mm, the diameter of the water outlet hole 210 is 4.4mm, and the length of the water outlet hole 210 is 13mm. Through these size restrictions, it is ensured that the flow cross section and length of the water mixing path remain consistent with existing water mixing faucets, thereby avoiding changes in the amount of water mixing. At this time, the center water inlet hole 110 needs to be opened to the connecting section 200.

[0040] In this embodiment, the water mixing anti-blocking faucet is made of stainless steel material to avoid maintenance replacement caused by corrosion.

[0041] Further, a ceramic coating can be provided on the surface of the water mixing anti-blocking faucet by spraying or deposition, especially on the inner walls of the center water inlet hole 110, the side water inlet hole 120 and the water outlet hole 210, thereby improving the wear resistance and corrosion resistance, and further improving the service life of the water mixing anti-blocking faucet and reducing maintenance costs.

[0042] The water mixing anti-blocking faucet provided in this embodiment improves the short service life caused by the easy corrosion of ordinary water mixing faucets and the need for frequent inspection, verification and replacement of employees after blocking, greatly reducing the workload of employees and the purchase cost of water mixing faucets. Compared with the technical solution of adding a filtering device to the water mixing conveying pipeline, the water mixing anti-blocking faucet provided in this embodiment can significantly reduce the modification cost and shorten the cycle, and directly replace the original faucet through structure and size control, and is flexible in application.

[0043] In the water mixing process in the production process, the water mixing enters the water faucet installation chamber of the water faucet assembly through the conveying pipeline. The water mixing converges in the center water inlet hole 110 through the inlet of the center water inlet hole 110 and the inlets of the plurality of side water inlet holes 120, and then flows into the inlet of the water outlet hole 210 through the outlet of the center water inlet hole 110. Subsequently, the water mixing is discharged through the outlet of the water outlet hole 210 and enters the conveying pipeline required for water mixing, achieving the purpose of conveying and controlling the amount of water mixing.

[0044] When foreign matter appears in the conveyed water mixing, the center water inlet hole 110 is blocked, or the center water inlet hole 110 and part of the side water inlet holes 120 are blocked, or part or all of the side water inlet holes 120 are blocked, the water mixing can be guaranteed to pass through the channel without changing the channel diameter, thereby achieving the effect of avoiding blocking and not changing the amount of water mixing, i.e. achieving the purpose of preventing blocking by realizing the multi-inlet and single-outlet mode.

[0045] In order to verify the effect of the water-injected anti-clogging faucet provided in this embodiment, an experimental method simulating on-site working conditions was adopted. Under the conditions of a certain pressure difference and the addition of mechanical impurities of a certain particle size, data such as the flow rate, the first channel blockage time, and the cumulative number of blockages were tracked within a certain experimental time. The anti-clogging faucet did not have any blockage problems during the experimental time, and the cumulative number of blockages was 0. The anti-clogging effect was significantly better than that of ordinary faucets, and the blockage problem of the water-injected faucet was solved. In addition, the flow rate was accurately controlled. The specific situation is shown in Table 1.

[0046] Table 1 Statistics of water-addition anti-clogging faucet experiment data

[0047]

[0048] As can be seen from Table 1, the water-injection anti-clogging water nozzle provided in this embodiment can effectively solve the problem of water nozzle clogging, avoiding the problems of frequent clogging of ordinary water-injection water nozzles causing a reduction in water volume or even no water injection, which may lead to blockage of oil pipelines, load increase and lying wells, as well as corrosion and blockage of water nozzles, increased workload for employee inspection, calibration and replacement of water nozzles, and purchase costs.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
