Description

Technical Field

[0001] The present application relates to the field of subsea exploration technologies, and particularly to a fluid flux sliding monitoring device and method based on electro-thermal linkage. Background Art

[0002] In related technologies, there are still a large number of un-explored oil and gas resources on the seabed. Existing seabed fluid flux monitoring means include sediment sampling and laboratory analysis, acoustic or seismic wave methods, and fiber optic sensing technologies. However, sediment sampling and laboratory analysis will damage the original state of the medium, and gas escape or phase changes may be caused during the sampling process. At the same time, the time cost is high, and real-time or long-term continuous monitoring cannot be achieved; acoustic or seismic wave methods are greatly affected by background noise, the data signal-to-noise ratio is low, and only a single medium can be monitored; fiber optic sensing technologies are complex in installation and maintenance, and special equipment is required for deep-sea deployment. In summary, existing seabed fluid flux monitoring means generally face problems such as difficulty in multi-phase discrimination, low spatio-temporal resolution, and insufficient long-term stability during the subsea exploration process, and it is impossible to perform layer-by-layer monitoring on the monitoring area to obtain more refined and accurate seabed fluid flux data.

[0030] As Figure 4 shown, Figure 4 is a schematic diagram of the sliding transmitter 211. The sliding transmitter 211 includes a first slider 610, a first telescopic joint 620, a sliding resistance heating rod 630, a sliding heat insulation plate 640, and a sliding emission electrode 650.

[0031] In some embodiments, the sliding transmitter 211 may include a first slider 610, a sliding resistance heating rod 630, a sliding heat insulation plate 640, and a sliding emission electrode 650. One end of the first slider 610 is connected to the sliding heat insulation plate 640, the sliding resistance heating rod 630, and the sliding emission electrode 650, and the other end of the first slider 610 is connected to the first slide rail 212. In this embodiment, the sliding transmitter 211 does not provide the first telescopic joint 620, and the sliding transmitter 211 cannot perform telescopic operations.

[0032] As Figure 5 shown, Figure 5It is a schematic diagram of a sliding receiver, which includes a second slider 710, a second telescopic joint 720, a sliding temperature sensor 730, and a sliding receiving electrode 740. The second telescopic joint 720 can automatically extend or contract a certain distance. When the second telescopic joint 720 extends, the area of the monitored area of a certain layer can be reduced, thereby realizing the measurement of a fine area. One end of the second telescopic joint 720 is connected to the sliding temperature sensor 730 and the sliding receiving electrode 740. The sliding receiving electrode 740 is the negative electrode. The other end of the second telescopic joint 720 is connected to the second slider 710.

[0033] In some embodiments, the sliding receiver may include a second slider 710, a sliding temperature sensor 730, and a sliding receiving electrode 740. One end of the second slider 710 is connected to the sliding temperature sensor 730 and the sliding receiving electrode 740. The other end of the second slider 710 is connected to the slide rail.

[0034] In some embodiments, when the sliding transmitter 211 is provided with a first telescopic joint 620, the first sliding receiver 222, the second sliding receiver 311, and the third sliding receiver 313 are also provided with a second telescopic joint 720. When the sliding transmitter 211 is not provided with the first telescopic joint 620, the first sliding receiver 222, the second sliding receiver 311, and the third sliding receiver 313 are also not provided with the second telescopic joint 720.

[0035] As Figure 6 shown, Figure 6 it is a schematic diagram of the accessories of a fluid flux sliding monitoring device based on electrothermal linkage. Figure 6The fluid flux sliding monitoring device based on electro-thermal linkage in it is provided with a lead block 120 and a lifting ring 110 above the connecting plate 100. The lead block 120 is used to increase the counterweight when the fluid flux sliding monitoring device based on electro-thermal linkage sinks to the seabed, so that it can reach the preset monitoring area. The lifting ring 110 is used to move and transport the fluid flux sliding monitoring device based on electro-thermal linkage. When moving and transporting, it is moved and lifted by connecting the cable of the lifting ring 110 through a carrier tool. Among them, the number of lead blocks 120 can be multiple, aiming to solve the problem of providing a suitable counterweight for the fluid flux sliding monitoring device based on electro-thermal linkage; the number of lifting rings 110 can be multiple, aiming to make the fluid flux sliding monitoring device based on electro-thermal linkage stable during the moving and lifting process when the carrier tool transports the fluid flux sliding monitoring device based on electro-thermal linkage. Preferably, 4 lifting rings 110 are arranged at the four corners above the connecting plate 100 of the fluid flux sliding monitoring device based on electro-thermal linkage. A baffle 800 is arranged below the control cabin 400. The baffle 800 is used when the fluid flux sliding monitoring device based on electro-thermal linkage is operating. The first measuring plate 200 and the second measuring plate 300 below the baffle 800 are inserted into the seabed area. The baffle 800 restricts the further penetration of the fluid flux sliding monitoring device based on electro-thermal linkage, so that the baffle 800 and structures such as the control cabin 400 above the baffle 800 are above the seabed surface, providing a limiting effect when operating the fluid flux sliding monitoring device based on electro-thermal linkage, and also playing a role in protecting the control cabin 400.

[0036] In some embodiments, the control cabin 400 includes an electrical control cabin and a thermal control cabin. The electrical control cabin is used to process the electrical signal data obtained by the sliding receiving electrode 740, and the thermal control cabin is used to process the thermal signal data obtained by the sliding temperature sensor 730. Among them, the electrical control cabin and the thermal control cabin are arranged below the connecting plate 100 and above the baffle 800. In this space, the baffle 800 and the connecting plate 100 play a very good protective role for the electrical control cabin and the thermal control cabin. An ammeter is provided in the electrical control cabin, which can measure the current magnitude of each current path in real time. The electrical control cabin and the thermal control cabin can respectively receive and process electrical data and thermal data.

[0037] In some embodiments, the first measuring plate 200 and the second measuring plate 300 are symmetric about the central axis position of the connecting plate 100, the first slide rail 212 and the second slide rail 221 are symmetric about the central axis position of the first measuring plate 200, and the third slide rail 312 and the fourth slide rail 314 are symmetric about the central axis position of the second measuring plate 300.

[0038] In some embodiments, the first measurement plate 200 and the second measurement plate 300 are provided with cavity channels at the positions where the first slide rail 212, the second slide rail 221, the third slide rail 312, and the fourth slide rail 314 are located. The first slide rail 212, the second slide rail 221, the third slide rail 312, and the fourth slide rail 314 are respectively arranged in the corresponding cavity channels, and the mechanical structures of the first slide rail 212, the second slide rail 221, the third slide rail 312, and the fourth slide rail 314 are protected through the cavity channels.

[0039] In some embodiments, the first telescopic joint 620 and the second telescopic joint 720 are provided with cavities. The sliding resistance heating rod 630, the sliding emission electrode 650, and the sliding heat insulation plate 640 of the sliding transmitter 211 are respectively arranged in the cavity of the first telescopic joint 620, and the structures of the sliding resistance heating rod 630, the sliding emission electrode 650, and the sliding heat insulation plate 640 are protected through the cavity of the first telescopic joint 620. The sliding temperature sensor 730 and the sliding receiving electrode 740 in the first sliding receiver 222, the second sliding receiver 311, and the third sliding receiver 313 are respectively arranged in the cavity of the second telescopic joint 720, and the structures of the sliding temperature sensor 730 and the sliding receiving electrode 740 are protected through the cavity of the second telescopic joint 720. This protection is to prevent physical damage to the sliding resistance heating rod 630, the sliding emission electrode 650, the sliding heat insulation plate 640, the sliding temperature sensor 730, and the sliding receiving electrode 740 caused by impurities and hard objects on the seabed during the operation of the fluid flux sliding monitoring device based on electrothermal linkage.

[0040] In some embodiments, as Figure 7 shown, Figure 7 is a schematic diagram of the elongation of the telescopic joint in the fluid flux sliding monitoring device based on electrothermal linkage. Connect the cable to the sling 110 through the carrier vehicle, and gradually lower the fluid flux sliding monitoring device based on electrothermal linkage to the seabed surface. Under the weight ballast of the lead block 120, the fluid flux sliding monitoring device based on electrothermal linkage gradually inserts into the seabed until the baffle 800 is flush with the seabed surface. The sliding transmitter 211, the first sliding receiver 222, the second sliding receiver 311, and the third sliding receiver 313 are initially located at the top of the slide rail, and slide downward simultaneously and remain at the same horizontal plane in real time at the start of the measurement. Stop sliding when reaching the first layer, and start measuring the target layer at the moment, and stop measuring at the time after an interval of time. Among them, the sliding resistance heating rod 630 in the sliding transmitter 211 is continuously and uniformly heated at the rated power, and at the same time, a fixed voltage is applied between the sliding emission electrode 650 and the sliding receiving electrode 740. According to the electrothermal physical field coupling mechanism and constraint conditions, The three-phase volume fractions in three measurement directions of the target layer within a certain time, and then the average three-phase volume fraction distribution of the first layer can be obtained. After that, the sliding transmitter 211 and the first sliding receiver 222, the second sliding receiver 311, and the third sliding receiver 313 continue to slide down to the second layer and measure the average three-phase volume fraction of this layer. And so on. When sliding to the bottom end of the slide rail, the fine overall volume fraction distribution of n layers in the vertical direction can be obtained. The time used for the above measurement process is the measurement period. , and then in another measurement period the sliding transmitter 211 and the first sliding receiver 222, the second sliding receiver 311, and the third sliding receiver 313 move from the bottom end to the top end and measure the fine overall volume fraction within this period. Through the data measured at these two moments, the change in fluid flux within a certain time can be calculated, and continuous dynamic monitoring of this area can be carried out in subsequent measurement periods.

[0041] In some embodiments, to make it easier for the fluid flux sliding monitoring device based on electro-thermal linkage to be inserted into the seabed until the baffle 800 is flush with the seabed surface, the lower ends of the first measurement plate 200 and the second measurement plate 300 are set to be conical with the tip pointing downwards. When the fluid flux sliding monitoring device based on electro-thermal linkage touches the seabed, due to the smaller contact area at the lower ends of the first measurement plate 200 and the second measurement plate 300, the pressure on the seabed surface by the contact surfaces of the first measurement plate 200 and the second measurement plate 300 gradually increases under the influence of the gravity of the lead block 120, making it more convenient to insert into the seabed.

[0042] In some embodiments, when the fluid flux sliding monitoring device based on electro-thermal linkage monitors a sudden change in the overall volume fraction, such as the leakage of a submarine cold seep or when more precise measurement of a finer area of a certain layer is desired, the first telescopic joints 620 and the second telescopic joints 720 of the sliding transmitter 211 and the first sliding receiver 222, the second sliding receiver 311, and the third sliding receiver 313 extend outwards, which can reduce the area of the monitoring area of this layer, and thus achieve fine measurement of a smaller area of any layer.

In the case where the fluid flux sliding monitoring device based on electro-thermal linkage does not move, the difference between the first monitoring area and the second monitoring area lies only in the different monitoring directions.

[0069] If the measured volume fraction is the volume fraction at the intermediate moment of these two adjacent measurement periods, then the fluid flux change matrix of the overall area at these two moments can be calculated: ; Continue to measure the overall fluid flux distribution matrices at different periods and different horizons and correlate them with each other, and the three-dimensional dynamic migration process of solids, liquids, and gases can be deduced.
