Embodiment 1

[0027] Such as figure 1 As shown, a subsea oil field leakage prevention device of the present invention includes an oil pumping pipe 1, a water inlet pipe 2, at least one leakproof outer cover and at least one leakproof outer cover fixing device 8. The oil pumping pipe 1 and the water inlet pipe 2 are respectively Penetrating into the submarine oil field, each leak-proof outer cover fixing device 8 is fixedly connected to the seabed 6 respectively, and a leak-proof outer cover is fixedly connected to a leak-proof outer cover fixing device 8 in a one-to-one correspondence, the oil pumping pipe 1 and the water inlet pipe 2 Set in the leak-proof outer cover.

[0028] The principle of the present invention is that after part of the oil in the oil field overflows from the gap between the oil pumping 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 cover so that the oil cannot escape. Spread into the seawater...

Embodiment 2

[0042] Such as figure 2 As shown, the number of leak-proof outer covers in this embodiment is two, 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 setting structure is simple, easy to form, and has a good oil leakage prevention effect.

[0043] The leak-proof outer cover of this embodiment includes a square fixed frame, each corner of the square fixed frame is provided with a fixed post, each fixed post is fixedly connected to the fixed frame, and each fixed post is inserted into the seabed 6. Each fixed post is fixedly connected to 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 setting structure is simple, easy to form, and has a good fixing effect on the leak-proof outer cover.

[0044] The rest of this embodiment is the...

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 present invention relates to the technical field of environmental protection engineering equipment, in particular to a submarine oil field leakage prevention device and a leakage prevention method thereof. Background technique [0002] In the prior art, in order to easily insert the oil pumping pipe and the water inlet pipe, the diameter of the oil pumping pipe is often slightly smaller than the diameter of the oil field outlet, and the pipe 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 pumping pipe and the oil outlet, and the gap between the water inlet pipe and the water inlet, and finally escape into the seawater, drifting around the world with the seawater. . It not only causes seawater pollution, but also reduces the oil collection rate, and there is a need for improvement. Summary of the invention ...
