Embodiment 1

[0027] Such as figure 1 As shown, a kind of anti-leakage device for subsea oil field of the present invention comprises oil suction pipe 1, water inlet pipe 2, at least one leakproof outer cover and at least one leakproof outer cover fixing device 8, and described oil suction pipe 1 and described water inlet pipe 2 are respectively Penetrating into the subsea oil field, each leak-proof outer cover fixing device 8 is fixedly connected with the sea bottom 6 respectively, one leak-proof outer cover is fixedly connected with one leak-proof outer cover fixing device 8 one by one, the oil suction pipe 1 and the water inlet pipe 2 Set in the leak-proof outer cover.

[0028] The principle of the present invention is: after part of the oil in the oil field overflows from the gap between the oil extraction pipe 1 and the oil outlet and the gap between the water inlet pipe 2 and the water inlet, it will be blocked by the leak-proof outer cover, so that the oil cannot escape. Scatter in ...

Embodiment 2

[0042] Such as figure 2 As shown, the number of leak-proof outer covers in this embodiment is two, and the oil suction pipe 1 is arranged in one of the leak-proof outer covers, and the water inlet pipe 2 is arranged in the other leak-proof outer cover. The arrangement has a simple structure, is easy to form, and has a good effect of preventing oil leakage.

[0043] The leak-proof outer cover of this embodiment includes a square fixed frame, each corner of the square fixed frame is respectively provided with a fixed column, and each fixed column is fixedly connected with the fixed frame respectively, and each fixed column is respectively inserted into the seabed 6, Each fixing column is fixedly connected with the seabed 6 respectively, the leak-proof outer cover is embedded in the square fixed frame, and the outer wall of the leak-proof outer cover abuts against the inner wall of the square fixed frame. The arrangement has a simple structure, is easy to form, and has a good f...

Abstract

The invention relates to the technical field of environmental-friendly engineering equipment, in particular to an offshore oilfield leakage preventing device. The offshore oilfield leakage preventing device comprises an oil pumping pipe, a water inlet pipe, at least one leakage preventing outer cover and at least one leakage preventing outer cover fixing device. The oil pumping pipe and the water inlet pipe penetrate into an offshore oilfield. Each leakage preventing outer cover fixing device is fixedly connected with the seabed. The leakage preventing outer covers are fixedly connected with the leakage preventing outer cover fixing devices in a one-to-one corresponding mode. The oil pumping pipe and the water inlet pipe are arranged in the leakage preventing outer covers. The offshore oilfield leakage preventing device is simple in structure and capable of effectively preventing oil from being dispersed into the sea, seawater is prevented from being polluted by oil, the collecting rate of oil can be increased, and reliability is high.

Description

technical field [0001] The invention relates to the technical field of environmental protection engineering equipment, in particular to a leak-proof device and a leak-proof method for a subsea oil field. Background technique [0002] In the prior art, in order to be easy to insert the oil extraction pipe and the water inlet pipe, the diameter of the oil extraction pipe is often slightly smaller than the diameter of the oil outlet of the oil field, and the diameter of the water inlet pipe is slightly smaller than the diameter of the oil field water inlet. Under this structure, part of the oil in the oil field will overflow from the gap between the oil extraction pipe and the oil outlet and the gap between the water inlet pipe and the water inlet, and finally escape into the sea water, drifting with the sea water to all parts of the world . Not only caused the pollution of seawater, but also reduced the oil collection rate, there is a need for improvement. Contents of the i...
