Description

Technical Field

[0001] The utility model relates to the technical field of oil production, in particular to a device for preventing oil production pipelines from being blocked. Background Art

[0002] Petroleum is one of the main objects of geological exploration. It is a viscous, dark brown liquid known as the blood of industry. Petroleum is stored in some areas of the upper crust. Its main components are a mixture of various alkanes, cycloalkanes and aromatic hydrocarbons.

[0003] After oil is extracted, it needs to be transported through pipelines. Because oil contains sand and gravel particles, oil blocks and other sediments, during the transportation process, the sediments are deposited on the inner wall of the pipeline, causing the inner wall of the pipeline to narrow, thereby obstructing oil transportation and seriously affecting the normal transportation of oil. Utility Model Content

[0004] The utility model aims to provide an anti-blocking oil production pipeline device, which can effectively prevent blockage during oil transportation and improve oil transportation efficiency.

[0005] The purpose of this utility model is achieved through the following technical solutions:

[0006] A device for preventing oil production pipeline from being blocked comprises a first main pipe, two first branch pipes connected to the first main pipe, a filter device connected to the liquid outlet end of each first branch pipe, a second branch pipe arranged at the liquid outlet end of each of the filter devices, and a second main pipe connected to the liquid outlet ends of the two second branch pipes; each of the first branch pipes is provided with a valve; and each of the filter devices is provided with a heating unit.

[0007] In the above scheme, by setting up a filtering device, sedimentary materials such as sand, oil blocks, etc. in the oil can be filtered to prevent sediments from being deposited in the second main pipe, which may cause obstruction or blockage of oil transportation; by setting up a heating part, the viscosity of the oil can be reduced and the smoothness of oil filtering can be improved; by setting up two first branches, two second branches and two filtering devices, two transportation lines can be formed during the transportation process. During daily transportation, only one of the transportation lines (including a first branch pipe + filtering device + second branch pipe) is unblocked. When the filtering device in the transportation line is blocked due to excessive sediment, the valve in the transportation line is closed and the valve in the other transportation line is opened, so that the oil is transported along the transportation line with the open valve, ensuring uninterrupted oil transportation; at the same time, the blocked filtering device in the closed transportation line is cleaned to be ready for transportation at any time. By setting up two transmission lines and providing a filtering device in each transmission line, it is possible to ensure that the oil in each line can be filtered, effectively reducing impurities in the oil flowing into the second main pipe, and avoiding obstruction of the transmission of the second main pipe; at the same time, by setting up two transmission lines, alternating transmission is possible to ensure uninterrupted transmission, effectively overcoming the defect of interrupted oil transmission due to cleaning of the filtering device when only one transmission line is set.

[0008] Preferably, the filtering device comprises a filter box and a filter screen arranged in the filter box.

[0009] In the above scheme, the structure of the filtering device is further defined, and the filtering purpose can be achieved by setting a filtering net.

[0010] Preferably, a filter cover is provided on the top of the filter box, and the filter net can be taken out from the top of the filter box.

[0011] In the above scheme, by providing a filter cover, the filter net can be taken out from the filter box, so that the filter net can be cleaned when the filter net is clogged.

[0012] Preferably, the inner wall of the filter box is provided with a support ring for supporting the filter screen; the top end of the filter screen is provided with a fixing rod, and the fixing rod can abut against the bottom surface of the filter cover.

[0013] In the above scheme, the filter net can be supported by providing a support ring, and the fixing rod can be squeezed when the filter cover is closed by providing a fixing rod, so that the filter net can be stably set in the filter net when working.

[0014] Preferably, the filter screen comprises a plurality of filter screens whose mesh apertures decrease successively from top to bottom, and the plurality of filter screens are fixed by connecting columns.

[0015] In the above scheme, by setting up multiple filter screens, the oil can be graded and filtered to improve the filtering efficiency of the oil; by setting up connecting columns, the filter screens can be connected and supported, and multiple filter screens can be taken out together when installing or removing the filter screens, thereby improving the convenience of operation.

[0016] Preferably, the heating part comprises a heating wire spirally arranged in an interlayer of the filter box side wall.

[0017] In the above solution, the heating wire is spirally arranged, so that the heating uniformity of the heating wire can be improved.

[0018] Preferably, the outer wall of the filter box is provided with a heat-insulating layer.

[0019] In the above scheme, by providing a heat-insulating layer, the heat loss in the filter box can be reduced and the energy utilization rate can be improved.

[0020] Preferably, the first branch pipe and the filter box, as well as the first branch pipe and the first main pipe are detachably connected.

[0021] In the above scheme, when the first branch pipe is blocked, the first branch pipe can be disassembled from the first main pipe for easy cleaning. The premise for completing this operation is that the connection between the first main pipe and the first branch pipe is detachably provided with a pipe cover to prevent oil from leaking along the connection between the first main pipe and the first branch pipe after the first branch pipe is disassembled.

[0022] Compared with the prior art, the beneficial effects of the utility model are:

[0023] By setting up a filtering device, sedimentary materials such as sand and oil blocks in the oil can be filtered to prevent sediments from being deposited in the second main pipe, which would cause the oil transportation to be blocked or clogged. By setting up two first branch pipes, two second branch pipes and two filtering devices, two transportation lines can be formed during the transportation process. During daily transportation, only one of the transportation lines (including a first branch pipe + filtering device + second branch pipe) is kept unobstructed. When the filtering device in the transportation line is blocked due to excessive sediment, the valve in the transportation line is closed and the valve in the other transportation line is opened, so that the oil can be transported along the transportation line with the open valve, ensuring uninterrupted oil transportation. At the same time, the blocked filtering device in the closed transportation line is cleaned to be ready for transportation at any time. By setting up two transmission lines and providing a filtering device in each transmission line, it is possible to ensure that the oil in each line can be filtered, effectively reducing impurities in the oil flowing into the second main pipe, and avoiding obstruction of the transmission of the second main pipe; at the same time, by setting up two transmission lines, alternating transmission is possible to ensure uninterrupted transmission, effectively overcoming the defect of interrupted oil transmission due to cleaning of the filtering device when only one transmission line is set.

[0028] Below in conjunction with the attached Figures 1 to 3 , the technical solutions in the embodiments of the utility model are clearly and completely described, but the protection scope of the utility model is not limited to the following.

[0029] Example 1

[0030] A device for preventing oil production pipeline from being blocked, such as Figure 1 and Figure 2 As shown, it includes a first main pipe 100, two first branch pipes 110 connected to the first main pipe 100, a filter device connected to the liquid outlet end of each first branch pipe 110, a second branch pipe 120 arranged at the liquid outlet end of each of the filter devices, and a second main pipe 130 connected to the liquid outlet ends of the two second branch pipes 120; each of the first branch pipes 110 is provided with a valve (existing technology, not shown in the figure); each of the filter devices is provided with a heating unit. Further, the filter device includes a filter box 150, and a filter screen 140 arranged in the filter box 150. Further, the heating unit includes a heating wire spirally arranged in the side wall interlayer of the filter box 150 (existing technology, not shown in the figure). Further, the outer wall of the filter box 150 is provided with a heat preservation layer (existing technology, not shown in the figure).

[0031] Working principle: The oil extracted from the oil pump (existing technology, not shown in the figure) is first transported to the first main pipe 100, and then transported to the second main pipe 130 through two transmission lines. Figure 1 and Figure 2As shown, each transmission line includes a first branch pipe 110, a second branch pipe 120, and a filtering device connected to the first branch pipe 110 and the second branch pipe 120. During daily transportation, only the valve in one of the transmission lines is opened, and the valve in the other transmission line is closed. After the oil is transported to the filter box 150 in the open transmission line, the sediment is filtered through the filter 140, and then it is transported to the second main pipe 130 through the second branch pipe 120. When the filter 140 in the transmission line is blocked, the valve in the transmission line is closed, and another transmission line is immediately opened to allow the oil to be transported along the other transmission line. In this process, the blocked filter 140 is cleaned so that the transmission line can be prepared to replace the transmission line at any time when the transmission line is blocked.

[0032] It is worth noting that the main delivery pipeline in the present invention is the second main pipe 130, the length of the first main pipe 100 is relatively short, and the filtering device is equivalent to being arranged at the source of the second main pipe 130, so that the second main pipe 130 can be ensured to be unblocked to the greatest extent.

[0033] Example 2

[0034] On the basis of Example 1, Figure 1 and Figure 2 As shown, a filter cover 160 is disposed on the top of the filter box 150, and the filter screen 140 can be taken out from the top of the filter box 150. Further, a support ring 170 for supporting the filter screen 140 is disposed on the inner wall of the filter box 150; Figure 3 As shown, a fixing rod 180 is disposed at the top of the filter 140, and the fixing rod 180 can abut against the bottom surface of the filter cover 160. Further, the filter 140 includes a plurality of filter screens 140 with mesh apertures decreasing from top to bottom, and the plurality of filter screens 140 are fixed by connecting columns 190.

[0035] Working principle: When the filter 140 is installed, the filter 140 is placed on the support ring 170, and then the filter cover 160 is closed. Because the filter cover 160 and the fixing rod 180 can abut, the filter 140 can be stably limited to the filter box 150 under the action of the support ring 170 and the fixing rod 180 to ensure the smooth progress of the filtering work. When filtering, the sediments are blocked on different filter screens 140 in turn through the filter screens 140 with different apertures to achieve the purpose of graded filtering; when the filter screen 140 is blocked, the filter cover 160 is opened, and the fixing rod 180 is dragged by hand to take out the filter screen 140.

[0036] Example 3

[0037] On the basis of Example 1 or Example 2, the first branch pipe 110 and the filter box 150, as well as the first branch pipe 110 and the first main pipe 100 are detachably connected, such as being fixed by bolts, etc. In specific implementation, when one of the first branch pipes 110 is blocked, the first branch pipe 110 can be directly removed from the first main pipe 100 and the filter device, so as to facilitate cleaning of the blocked first branch pipe 110.
