Background
Oil is one of essential energy sources in daily life of human beings, and in 20 ages, the exploitation of oil is mainly onshore exploitation, and with the development of science and technology, human beings detect more and more submarine oil fields, and the exploitation of submarine oil is also greatly developed. When the submarine oil is exploited, the oil production pipe needs to penetrate through seawater and the seabed until the oil production pipe extends into an oil layer, and the submarine oil is exploited through the shaft and the oil production pipe. If the shaft or the oil production pipe leaks, oil can leak into the ocean, and further the ecological environment of the ocean is influenced.
The current submarine oil production technology is mature, and as long as no strong geological disasters (such as strong submarine earthquakes and tsunamis) occur at sea, a shaft or an oil production pipe is not easy to generate sudden large-scale oil leakage; if a small scale leak in the wellbore or riser has occurred, a large scale leak in the wellbore or riser may be caused when a minor geological disaster occurs at sea. However, when the shaft or the oil production pipe leaks oil on a small scale, the shaft and the oil production pipe are positioned at the bottom of the seabed, and leaked oil cannot invade into seawater in a short time, so that an oil film cannot appear on the seawater temporarily, and mining personnel cannot find the leaked oil by naked eyes; and because the scale of oil leakage is small, sensors in the shaft and the oil extraction pipe are difficult to monitor the oil leakage, and mining personnel cannot maintain and repair the shaft and the oil extraction pipe in time, so that the large-scale sudden oil leakage buries the underhung pen.

When the produced oil is introduced into the soil sample through the oil pipe 230, the fourth resistance sensor 260 may detect a real-time resistance value R4 of the soil sample; when the real-time resistance value R4 at the fourth resistance sensor 260 exceeds the static resistance value R1 by a certain range, it is proved that the oil has diffused to the fourth resistance sensor 260, and at this time, the time required for the oil to diffuse to the fourth sensor (i.e., the time difference between when oil transportation starts and when the real-time resistance value R4 exceeds the static resistance value R1 by a certain range) is recorded; after repeated experiments, the position of the fourth resistance sensor 260 is kept unchanged, the speed of oil transportation from the oil pipeline 230 to the soil sample is changed (namely, the oil leakage rate C is changed), the time required for oil to diffuse to the fourth sensor (namely, the diffusion time t) is recorded, and the central processing unit can calculate the relation curve between the oil leakage rate C and the diffusion time t of the oil.
When an oil leakage accident occurs on the seabed, oil can flow in the seabed soil, so that the real-time resistance value R2 of a certain part of the seabed soil is changed. Monitoring devices 300 can real-time supervision seabed soil's real-time resistance value R2, and central processing unit can compare static resistance value R1 with real-time resistance value R2, if real-time resistance value R2 surpasses static resistance value R1 certain limit, then prove that the oil leakage accident has taken place in the seabed, send alarm signal this moment, with the suggestion mining personnel, the seabed has taken place to be located the pit shaft, the seabed oil leak accident that the sensor monitoring in the oil recovery pipe can not just can not be observed by naked eyes, in order to in time remedy by the mining personnel, so can reduce on a large scale, the probability that the oil leak accident of suddenness takes place, with the probability that reduces oil pollution marine environment.
After oil leakage is found, the central processing unit obtains the floating acceleration a of the oil, obtains the flowing speed v of water in the seabed soil through the flowing speed sensor 330, obtains an activity curve of the oil floating in the seabed soil through the floating acceleration a of the oil in the seabed soil and the flowing speed v of the water in the seabed soil, and can judge the oil leakage position according to the activity curve of the oil floating in the seabed soil when the resistance of a certain monitoring point in the seabed soil changes and exceeds a set value (namely the real-time resistance value R2 exceeds the static resistance value R1 within a certain range), so that mining personnel can make leakage repairing treatment in time.
Since the oil is diffused in the seabed soil, after the oil leakage level is determined, the second resistance sensor 320 at the same level as the oil leakage point also monitors that the resistance is abnormal after a period of time t1 (i.e. the real-time resistance value R5 exceeds the static resistance value R1 by a certain range), and since the cpu has already obtained the relationship curve between the leakage rate C and the diffusion time t, the actual leakage rate C1 of the oil is obtained according to the relationship curve between the leakage rate C and the diffusion time t of the oil. Because different oil leakage degrees can influence the method for treating oil leakage, after the actual leakage rate C1 of oil is obtained, oil extraction personnel can conveniently judge how to perform leakage repair.
The above are all preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
