Description

Technical Field

[0001] The utility model relates to an oil and gas pipeline detection device, more precisely, an oil and gas pipeline leakage early warning device. Background Art

[0002] During oilfield production, leaks in oil and gas pipelines pose a comprehensive threat, affecting human safety, environmental protection, and economic development. They not only cause personal injury: oil and gas pipeline accidents can lead to explosions, fires, or toxic gas leaks, all of which can threaten the safety and health of personnel and even cause injury or death. Leaks, especially in densely populated areas, can result in significant casualties. Furthermore, they cause environmental damage: leaked oil and gas can severely harm the surrounding natural environment, including soil and water pollution. This pollution not only affects river flows, threatening the survival of fish and other species, but can also affect vegetation growth. Oil and gas leaks can cause long-term impacts and severe pollution, particularly in wetlands, forests, and ecological zones. They also cause economic losses: oil and gas pipeline leaks often result in significant economic losses. The fires and explosions caused by leaks can damage factories, buildings, and other infrastructure, resulting in significant financial losses for both the government and businesses. Furthermore, cleaning up and repairing the damage caused by leaks requires significant funding and time. Therefore, we must attach great importance to leakage monitoring of oil and gas pipelines and take effective measures to prevent leakage accidents and reduce the possible harm they may cause.

[0003] The cross-river process protection uses a combination of protective casings and video surveillance. The protective casings provide initial protection, controlling leaks within a certain range. The surveillance system transmits on-site images to the duty room in real time, allowing duty personnel to observe the on-site situation through the monitoring system so that they can detect and handle leaks if the protective casing fails. This method can reduce the hazards of oil and gas leaks to a certain extent, but it can only be visually detected after a large amount of crude oil has leaked. Moreover, this method cannot provide early warning of pipeline leaks in the initial stage and cannot notify duty personnel in real time. If not discovered in time, it will affect the further treatment of oil and gas leaks, posing certain safety risks. After observing an on-site leak, this method cannot cut off the valve to perform preliminary treatment to prevent the spread of pollution, and the human intervention capability is weak.

DETAILED DESCRIPTION

[0020] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] like Figure 1 As shown, the oil and gas pipeline leakage warning device includes a pair of onshore modules S, which are symmetrically arranged on both sides of the river R. A submerged pipe 12 is provided between the onshore modules S, and the submerged pipe 12 connects the onshore modules S.

[0022] The onshore module S includes a pipeline assembly P and a control cabinet 9. The pipeline assembly P includes a longitudinally arranged first pipeline 1 and a longitudinally arranged second pipeline 2. A transversely arranged third pipeline 3 and a transversely arranged bypass pipeline 4 are provided between the first pipeline 1 and the second pipeline 2.

[0023] The first pipeline 1 is provided with a first valve 7 , the second pipeline 2 is provided with a second valve 5 , the third pipeline 3 is provided with a main electric valve 6 , and the bypass pipeline 4 is provided with a bypass electric valve 8 .

[0024] One end of the bottom pipe 12 is connected to one of the second pipes 2 , and the other end of the bottom pipe 12 is connected to the other second pipe 2 .

[0025] A casing 13 is provided on the periphery of the submerged pipe 12, and casing plugs 14 are provided at both ends of the casing 13. A pair of hollow ground detection piles 10 are provided on the outer wall of the casing 13. The ground detection piles 10 are connected to the casing 13, and a plurality of test probes 11 are provided on the ground detection piles 10.

[0026] It should be noted that the control cabinet 9 receives the signal from the test probe 11 and controls the main electric valve 6 and the bypass electric valve 8 .

[0027] The working mode of the oil and gas pipeline leakage early warning device is described below.

[0028] Under normal circumstances, that is, when there is no leakage of oil and gas, the first valve 7, the second valve 5, and the main electric valve 6 are all in the open state, and the bypass electric valve 8 is in the closed state.

[0029] When unloading occurs in the submerged pipeline 12 and oil and gas leak into the casing 13, the test probe 11 of the ground detection pile 10 will detect a change in the gas concentration in the casing 13, and the combustible gas concentration and carbon dioxide concentration exceed the set threshold value. At this time, the control cabinet 9 will issue a remote alarm, and at the same time, the two main electric valves 6 will be closed and the two bypass electric valves 8 will be opened, thereby completing the emergency measures.

[0030] This oil and gas pipeline leak warning device relies on sensor technology and data analysis methods to quickly and accurately detect pipeline leaks. It monitors parameters such as combustible gas and carbon dioxide concentrations in the pipeline in real time and transmits this data to a control system. The control system determines whether a leak is present by comparing and analyzing real-time data with preset thresholds and applying pattern recognition algorithms. Once a leak is detected, the system immediately sounds an alarm and initiates emergency measures, closing valves on both sides to minimize losses caused by the leak and reduce production costs. Real-time monitoring and early warning reduce resource waste and environmental pollution caused by leaks, lowering production costs for the company. The device improves work efficiency by enabling automated monitoring and rapid response, reducing the frequency and intensity of manual inspections, improving work efficiency, ensuring safe operation, and promptly detecting and addressing leaks, avoiding safety incidents caused by leaks and protecting the lives of the company and its personnel.

[0031] Obviously, the embodiments described above are only part of the embodiments of the present application, rather than all the embodiments. The drawings provide preferred embodiments of the present application, but do not limit the patent scope of the present application.
