A leak-proof subsea oil drilling workstation

Abstract

The invention relates to a leak-proof submarine oil drilling work station which comprises an airtight work station body and supporting feet arranged at the lower portion of the work station body. The airtight work station body comprises living accommodation and device working accommodation. The device working accommodation is provided with an oil pumping unit, an oil conveying pipe, a seawater injection machine and a seawater injection pipe. An oil overflow channel is formed in the position, on the periphery of the oil conveying pipe, of the device working accommodation. The oil overflow channel is connected with an oil overflow pool. A seawater overflow channel is formed in the position, on the periphery of the seawater injection pipe, of the device working accommodation. The seawater overflow channel is connected with a seawater overflow pool. An oil pumping pipe and a seawater pumping pipe are inserted into the oil overflow pool and the seawater overflow pool respectively. Overflowing oil and overflowing seawater are pumped and sent to the seawater surface by the oil overflow pool and the seawater overflow pool through the oil pumping pipe and the seawater pumping pipe respectively. The leak-proof submarine oil drilling work station effectively prevents the damage effect from being caused after oil leakage and seawater leakage, and ensures safety. Due to the arrangement of a first-level sealing door and a second-level sealing door, the safety coefficient of workers when the workers go in and out the work station is further improved.

Description

technical field [0001] The invention relates to the field of oil drilling platforms, in particular to a subsea oil drilling workstation. Background technique [0002] Since the subsea oil drilling workstation is installed on the seabed, its structure includes an airtight workstation and feet arranged at the lower part of the workstation. The workstation includes a living cabin and an equipment working cabin. The equipment working cabin is equipped with a pumping unit, an oil delivery pipe, a water injection machine and a water injection pipe. The interface of the oil delivery pipe and water injection pipe is in the equipment working compartment, and leakage may occur due to vibration during operation, or when the joint is worn or the oil pipe is damaged, or the oil delivery pipe and water injection pipe are worn by the through hole of the workstation when passing through the workstation, there may be leakage. Oil spills, oil spills will not only affect the safety of worksta...

[0002] Since the subsea oil drilling workstation is installed on the seabed, its structure includes an airtight workstation and feet arranged at the lower part of the workstation. The workstation includes a living cabin and an equipment working cabin. The equipment working cabin is equipped with a pumping unit, an oil delivery pipe, a water injection machine and a water injection pipe. The interface of the oil delivery pipe and water injection pipe is in the equipment working compartment, and leakage may occur due to vibration during operation, or when the joint is worn or the oil pipe is damaged, or the oil delivery pipe and water injection pipe are worn by the through hole of the workstation when passing through the workstation, there may be leakage. Oil spills, oil spills will not only affect the safety of workstation equipment and personnel, but also pollute the working sea area, destroy the ecological environment of fish and birds in the vicinity, and even affect the lives of residents near the sea

In addition to the oil pipe, the water injection pipe may also leak water during use. For example, when the pipe interface or the oil delivery pipe and water injection pipe pass through the workstation, they are worn by the through hole of the workstation and leak sea water. In a confined space, water leakage means that the workstation will be soaked Therefore, it is necessary not only to use good-quality leak-proof equipment, but also to improve leak-proof awareness during operation, and more importantly, to take adequate measures to deal with leaks
