BRIEF DESCRIPTION OF THE DRAWINGS

[0042] Hereinafter, the present invention will be described in more detail based on embodiments and with reference to the accompanying drawings.

[0043] Figure 1 It is a schematic diagram of the structure of a blowout preventer provided by one embodiment of the present invention;

[0044] Figure 2 is a schematic diagram of an offshore platform provided by an embodiment of the present invention;

[0045] Figure 3 The present invention is a flowchart of a method for early warning of offshore oil safety equipment failure based on remote monitoring provided by an embodiment of the present invention. DETAILED DESCRIPTION

[0046] The present invention will be further described below in conjunction with the accompanying drawings.

[0047] When drilling for oil, a blowout preventer is installed on the casing head of the wellhead to control the blowout of high-pressure oil, gas, and water. When the oil and gas pressure in the well is very high, the blowout preventer can seal the wellhead (close it tightly). When heavy mud is pressed into the drill pipe, there is a four-way under the gate to replace the mud invaded by gas, increase the pressure of the liquid column in the well, and suppress the spray of high-pressure oil and gas.

[0048] Blowout preventer is the most important well control device, which plays an important role in drilling, especially in underbalanced drilling. The purpose of designing blowout preventer is to close the wellbore under pressure, maintain continuous control of the well, and circulate out the formation fluid entering the well.

[0049] BOP is the most important well control safety equipment. Once an emergency such as overflow, well kick, or blowout occurs during drilling operations, the BOP needs to be activated and shut down the well quickly. If the BOP fails at this time, it will lead to serious accidents such as blowouts. The working environment of the BOP is relatively harsh (usually on the seabed), which makes the BOP prone to failure, and the staff cannot discover it in time, which leads to safety accidents.

[0050] First, as Figure 1 , Figure 2 As shown, the embodiment of the present application provides a fault warning system for offshore oil safety equipment based on remote monitoring, wherein the offshore oil safety equipment is an underwater blowout preventer 10, comprising:

[0051] The installation chamber 120 is provided in the housing 110 of the blowout preventer 10;

[0052] A detection assembly, disposed in the installation chamber 120, for detecting the movement of the gate 130 of the blowout preventer 10;

[0053] A pressure gauge, provided on the oil cylinder 140 of the blowout preventer 10;

[0054] A hydraulic oil particle size detector, disposed in the oil cylinder 140, for detecting the composition of the hydraulic oil in the oil cylinder 140;

[0055] In the monitoring state, the movement of the gate plate 130 is detected by the detection component, and an abnormal operation alarm of the gate plate 130 is issued when the movement of the gate plate 130 is abnormal. The working condition of the hydraulic oil in the cylinder 140 is detected by the pressure gauge and the hydraulic oil particle size detector, and a hydraulic oil abnormality alarm is issued when the working condition of the hydraulic oil is abnormal.

[0056] It should be noted that the installation chamber 120 is arranged above the gate plate 130, and the side wall of the installation chamber 120 facing the gate plate 130 is made of wear-resistant tempered glass so that the detection component can detect the gate plate 130. The detection components are arranged corresponding to the number of the gate plates 130, that is, a pair of gate plates 130 is equipped with one detection component for detection.

[0057] It should be noted that the pressure gauge can detect the hydraulic oil pressure of the cylinder 140 to obtain the hydraulic oil working pressure. The probe of the hydraulic oil particle size detector is in the cylinder 140. The hydraulic oil particle size detector can monitor and analyze the oil particle size, cleanliness and contaminants of the hydraulic oil to obtain the hydraulic oil working composition. If the hydraulic oil working pressure exceeds the preset pressure range, an abnormal hydraulic oil working pressure alarm is issued to the ground or offshore platform 20; if the hydraulic oil working composition exceeds the preset composition range, an abnormal hydraulic oil working composition alarm is issued to the ground or offshore platform 20.

[0058] It should be noted that the hydraulic oil working pressure and the hydraulic oil working composition can be used to conduct a preliminary analysis of the cause of the abnormal movement of the gate 130 to determine whether it is caused by the abnormal hydraulic oil working pressure and / or the abnormal hydraulic oil working composition.

[0059] In some embodiments, the detection component includes:

[0060] A sensor, disposed in the installation chamber 120, for detecting the movement of the gate 130 of the blowout preventer 10;

[0061] The radiation detector is arranged in the installation room 120 and connected to the rotating device, and is used for performing radiation detection on the blowout preventer 10 .

[0062] It should be noted that the sensor can detect the movement of the gate 130 to obtain the movement of the gate 130. If the movement of the gate 130 is abnormal, an abnormal alarm of the gate 130 movement is issued, wherein the movement of the gate 130 includes the movement speed of the gate 130 and the movement position of the gate 130, and the abnormal alarm of the gate 130 movement includes the abnormal speed alarm of the gate 130 and the abnormal position alarm of the gate 130; that is: the movement of the gate 130 is detected by the sensor to obtain the movement speed of the gate 130 and the movement position of the gate 130; if the movement speed of the gate 130 is less than the movement speed If the gate 130 moves to a preset position, an alarm of abnormal position of the gate 130 is issued. In the process of closing the gate 130, not only the gate 130 needs to be closed in place, but also the closing speed of the gate 130 needs to be guaranteed. If the closing speed of the gate 130 is too low, it may cause the gate 130 to be untimely closed, thereby failing to prevent the occurrence of safety accidents. The upper limit of the movement speed can be set according to actual needs, and this application does not make specific limitations. The sensor can be an infrared imaging sensor, an infrared sensor, a camera, etc.

[0063] It should be noted that by rotating the radiographic detector through the rotating device and detecting the blowout preventer 10 through the radiographic detector, a radiographic detection result can be obtained. If the radiographic detection result exceeds the preset working condition, an abnormal radiographic detection alarm is issued, wherein the radiographic detection result can display the corrosion condition, deformation condition, etc. of the blowout preventer 10 (including the gate 130), and generally evaluate the physical working performance of the blowout preventer 10. The rotating device can be a universal ball shaft, and the present application does not specifically limit the specific form of the rotating device.

[0064] In some embodiments, the offshore oil safety equipment fault warning system based on remote monitoring also includes an oil component detector and a mud component detector. The oil component detector is used to detect the oil and gas components of the oil and gas in the well, and the mud component detector is used to detect the mud components of the mud in the well.

[0065] It should be noted that the probe (or collector) of the oil component detector and the probe (or collector) of the mud component detector are arranged in the well or in the blowout preventer 10. Different oil components and different mud components have different corrosion rates on the blowout preventer 10. Therefore, by collecting the oil components and the mud components and the duration of their contact with the blowout preventer 10, the corrosion condition of the blowout preventer 10 can be accurately estimated, and the usable time of the blowout preventer 10 can be estimated based on the oil components and the mud components.

[0066] It should be noted that the corrosion condition of the blowout preventer 10 can be estimated and the usable time of the blowout preventer 10 can be predicted by a corrosion model. The corrosion model can be a neural network model, and the corrosion model can be corrected according to the radiographic detection result, so as to ensure the accuracy of the corrosion model in predicting the usable time of the blowout preventer 10.

[0067] In some embodiments, the offshore oil safety equipment fault warning system based on remote monitoring also includes a winding device 40 and multiple ocean current detectors, wherein the winding device 40 is arranged on the anchor chain 30 of the offshore oil platform, and is used to wind up or unfold the anchor chain 30 based on the ocean current information detected by the ocean current detector, wherein multiple ocean current detectors are arranged at different depths below the sea level.

[0068] It should be noted that, since the flow of water in the ocean occurs at different depths, it will directly exert force on the ocean platform 20 near the sea surface and exert force on the anchor chain 30 of the ocean platform 20 underwater. These forces will eventually be transmitted to the ocean platform 20, causing the ocean platform 20 to fluctuate or float, thereby affecting the stability of the ocean platform 20. The anchor chain 30 used to fix the ocean platform 20 usually has a certain sag due to its long length, that is, the anchor chain 30 is not in a straight state to fix the ocean platform 20 on the sea. The bottom of the anchor chain 30 is formed on the bottom of the anchor chain 30. When the force on one side of the offshore platform 20 is large, the corresponding anchor chain 30 will be "straightened (i.e., the straight length becomes longer)" under the force, so that the offshore platform 20 will fluctuate. Therefore, the anchor chain 30 on the side where the force is located can be tightened by the winding device 40 to offset the fluctuation of the offshore platform 20 caused by the "straightening" of the anchor chain 30. The winding device 40 can be an electric reel, and a plurality of winding devices 40 can be arranged on one anchor chain 30 according to the length of the anchor chain 30 to tighten the anchor chain 30 in sections.

[0069] It should be noted that the ocean current detector and the winding device 40 are usually arranged at the same depth. When tightening the anchor chain 30, multiple ocean current detectors can be used to detect multiple ocean current conditions at different depths below the sea level; based on the multiple ocean current conditions, the displacement of the ocean current on the offshore platform 20 is obtained; based on the displacement, the anchor chain 30 to be wound up is determined, and the anchor chain 30 to be wound up is wound up by the winding device 40, that is, if the displacement obtained by the ocean current conditions is to make the offshore platform 20 rotate to the right (or capsize), the anchor chain 30 on the left side of the offshore platform 20 is tightened by the winding device 40. At this time, under the action of the ocean current on the offshore platform 20 and the anchor chain 30, the anchor chain 30 "straightens", and tightening the anchor chain 30 by the winding device 40 can prevent the offshore platform 20 from fluctuating, thereby ensuring the stability of the offshore platform 20.

[0070] In summary, compared with the prior art, the advantages of the embodiments of the present application are that, by providing an installation chamber 120 in the housing 110 of the blowout preventer 10 and providing a detection component in the installation chamber 120, the movement of the gate 130 of the blowout preventer 10 can be detected in time, and an abnormal movement alarm of the gate 130 is issued when the movement of the gate 130 is abnormal; by providing a pressure gauge and a hydraulic oil particle size detector on the oil cylinder 140 of the blowout preventer 10, it is possible to detect whether the hydraulic oil in the oil cylinder 140 is working normally, and an abnormal hydraulic oil alarm is issued when the hydraulic oil is working abnormally, and the working condition of the blowout preventer 10 can be remotely monitored to ensure the safe use of the blowout preventer 10, which can solve the problem that the existing blowout preventer 10 is prone to failure, but the staff cannot find it in time, thereby causing safety accidents.

[0071] Second, as Figure 3 As shown, the embodiment of the present application provides a method for early warning of offshore oil safety equipment failure based on remote monitoring, which is applied to the offshore oil safety equipment failure early warning system based on remote monitoring as described in any one of the first aspects, including:

[0072] S101: Detecting the movement of the gate 130 by the detection component to obtain the movement status of the gate 130. If the movement status of the gate 130 is abnormal, an alarm indicating abnormal movement of the gate 130 is issued;

[0073] It should be noted that the detection assembly includes: a sensor, which is arranged in the installation chamber 120 and is used to detect the movement of the gate 130 of the blowout preventer 10; and a radiation detector, which is arranged in the installation chamber 120 and connected to the rotating device and is used to perform radiation detection on the blowout preventer 10.

[0074] In some embodiments, the movement of the gate 130 includes the movement speed of the gate 130 and the movement position of the gate 130, and the abnormal alarm of the movement of the gate 130 includes the abnormal alarm of the speed of the gate 130 and the abnormal alarm of the position of the gate 130;

[0075] The detection component detects the movement of the gate 130 to obtain the movement status of the gate 130. If the movement status of the gate 130 is abnormal, an abnormal alarm of the movement of the gate 130 is issued, including:

[0076] Detecting the movement of the gate plate 130 by a sensor to obtain the movement speed and movement position of the gate plate 130;

[0077] If the movement speed of the gate 130 is less than the upper limit of the movement speed, an abnormal speed alarm of the gate 130 is issued;

[0078] If the movement position of the gate plate 130 does not reach the preset movement position, an abnormal position alarm of the gate plate 130 is issued.

[0079] It should be noted that, in the process of closing the gate 130, not only is it necessary to close the gate 130 in place, but it is also necessary to ensure the closing speed of the gate 130. If the closing speed of the gate 130 is too low, it may cause the gate 130 to be unclosed in time, thereby failing to prevent the occurrence of safety accidents. The upper limit of the movement speed can be set according to actual needs, and this application does not make specific limitations. The sensor can be an infrared imaging sensor, an infrared sensor, a camera, etc.

[0080] S102: Detecting the pressure of the hydraulic oil in the oil cylinder 140 by the pressure gauge to obtain the hydraulic oil working pressure;

[0081] S103: If the hydraulic oil working pressure exceeds a preset pressure range, an abnormal hydraulic oil working pressure alarm is issued;

[0082] S104: Detecting the components of the hydraulic oil in the oil cylinder 140 by the hydraulic oil particle size detector to obtain the working components of the hydraulic oil;

[0083] S105: If the hydraulic oil working composition exceeds a preset composition range, an abnormal hydraulic oil working composition alarm is issued.

[0084] It should be noted that the pressure gauge can detect the hydraulic oil pressure of the cylinder 140 to obtain the hydraulic oil working pressure. The probe of the hydraulic oil particle size detector is in the cylinder 140. The hydraulic oil particle size detector can monitor and analyze the oil particle size, cleanliness and contaminants of the hydraulic oil to obtain the hydraulic oil working composition. If the hydraulic oil working pressure exceeds the preset pressure range, an abnormal hydraulic oil working pressure alarm is issued to the ground or offshore platform 20 (usually when the hydraulic oil working pressure is low, the gate 130 cannot be closed, or the speed of closing the gate 130 is too slow); if the hydraulic oil working composition exceeds the preset composition range (usually when the hydraulic oil has high particle size, high viscosity and many impurities, the speed of driving the gate 130 will be reduced), an abnormal hydraulic oil working composition alarm is issued to the ground or offshore platform 20, wherein the preset pressure range and the specific range of the hydraulic oil working composition can be set according to actual conditions.

[0085] It should be noted that the hydraulic oil working pressure and the hydraulic oil working composition can be used to conduct a preliminary analysis of the cause of the abnormal movement of the gate 130 to determine whether it is caused by the abnormal hydraulic oil working pressure and / or the abnormal hydraulic oil working composition.

[0086] In some embodiments, the offshore oil safety equipment failure early warning method based on remote monitoring further includes:

[0087] Rotate the ray detector by the rotating device, and detect the blowout preventer 10 by the ray detector to obtain the ray detection result;

[0088] If the radiation detection result exceeds the preset working condition, a radiation detection abnormality alarm is issued.

[0089] It should be noted that by rotating the radiographic detector through the rotating device and detecting the blowout preventer 10 through the radiographic detector, a radiographic detection result can be obtained. If the radiographic detection result exceeds the preset working condition, an abnormal radiographic detection alarm is issued, wherein the radiographic detection result can display the corrosion condition, deformation condition, etc. of the blowout preventer 10 (including the gate 130), and generally evaluate the physical working performance of the blowout preventer 10. The rotating device can be a universal ball shaft, and the present application does not specifically limit the specific form of the rotating device.

[0090] In some embodiments, the offshore oil safety equipment failure early warning method based on remote monitoring further includes:

[0091] Detect the oil composition in the well through the oil composition detector;

[0092] Detect the mud composition in the well by using a mud composition detector;

[0093] The remaining service life of the gate plate 130 when the movement speed of the gate plate 130 drops to the lower limit of the movement speed is evaluated based on the petroleum composition and / or the mud composition and the radiographic detection result.

[0094] It should be noted that the probe (or collector) of the oil component detector and the probe (or collector) of the mud component detector are arranged in the well or in the blowout preventer 10. Different oil components and different mud components have different corrosion rates on the blowout preventer 10. Therefore, by collecting the oil components and the mud components and the duration of their contact with the blowout preventer 10, the corrosion condition of the blowout preventer 10 can be accurately estimated, and the usable time of the blowout preventer 10 can be estimated based on the oil components and the mud components.

[0095] It should be noted that the corrosion condition of the blowout preventer 10 can be estimated and the usable time of the blowout preventer 10 can be predicted by a corrosion model. The corrosion model can be a neural network model, and the corrosion model can be corrected according to the radiographic detection result, so as to ensure the accuracy of the corrosion model in predicting the usable time of the blowout preventer 10.

[0096] It should be noted that, based on the X-ray detection results (including corrosion and deformation conditions), the petroleum composition, and the mud composition, the gate 130 movement speed model can be used to predict the remaining usage time of the gate 130 when the gate 130 movement speed drops to the lower limit of the movement speed, thereby providing accurate time for preparing to replace equipment in advance, wherein the gate 130 speed model can be a neural network model.

[0097] In some embodiments, the offshore oil safety equipment failure early warning method based on remote monitoring further includes:

[0098] Detect the current conditions at multiple locations at different depths below the sea level through multiple ocean current detectors;

[0099] Based on the ocean current conditions at multiple locations, the displacement of the ocean platform 20 caused by the ocean current is obtained;

[0100] The anchor chain 30 to be reeled is determined based on the action displacement, and the anchor chain 30 to be reeled is reeled by the reeling device 40 .

[0101] In some embodiments, obtaining the displacement of the ocean current on the offshore platform 20 based on the ocean current conditions at multiple locations includes:

[0102] Based on the ocean current conditions at multiple locations, the anchor chain 30 force of the ocean current and the platform force of the offshore platform 20 are obtained;

[0103] The applied displacement is obtained based on the applied force of the anchor chain 30 and the applied force of the platform.

[0104] It should be noted that, since the flow of water in the ocean occurs at different depths, it will directly exert force on the ocean platform 20 near the sea surface and exert force on the anchor chain 30 of the ocean platform 20 underwater. These forces will eventually be transmitted to the ocean platform 20, causing the ocean platform 20 to fluctuate or float, thereby affecting the stability of the ocean platform 20. The anchor chain 30 used to fix the ocean platform 20 usually has a certain sag due to its long length, that is, the anchor chain 30 is not in a straight state to fix the ocean platform 20 on the sea. The bottom of the anchor chain 30 is formed on the bottom of the anchor chain 30. When the force on one side of the offshore platform 20 is large, the corresponding anchor chain 30 will be "straightened (i.e., the straight length becomes longer)" under the force, so that the offshore platform 20 will fluctuate. Therefore, the anchor chain 30 on the side where the force is located can be tightened by the winding device 40 to offset the fluctuation of the offshore platform 20 caused by the "straightening" of the anchor chain 30. The winding device 40 can be an electric reel, and a plurality of winding devices 40 can be arranged on one anchor chain 30 according to the length of the anchor chain 30 to tighten the anchor chain 30 in sections.

[0105] It should be noted that the ocean current detector and the winding device 40 are usually arranged at the same depth and are located on the outside of the winding device 40 (i.e., on the side away from the marine platform 20). When tightening the anchor chain 30, multiple ocean current detectors can be used to detect multiple ocean current conditions at different depths below the sea level; based on the multiple ocean current conditions, the displacement of the ocean current on the marine platform 20 is obtained; based on the displacement, the anchor chain 30 to be wound up is determined, and the anchor chain 30 to be wound up is wound up by the winding device 40, that is, if the displacement obtained by the ocean current conditions is to make the marine platform 20 rotate to the right (or capsize), the anchor chain 30 on the left side of the marine platform 20 is tightened by the winding device 40. At this time, under the action of the ocean current on the marine platform 20 and the anchor chain 30, the anchor chain 30 is "straightened". Tightening the anchor chain 30 by the winding device 40 can prevent the marine platform 20 from fluctuating, thereby ensuring the stability of the marine platform 20.
