Technical Field

The invention belongs to the field of underwater production systems, and particularly relates to a hydraulic power station for providing a hydraulic power source for an underwater production system.

Background

Petroleum is an important energy source and a high-quality chemical raw material, and is an important strategic material related to the national civilization. Although the development of new energy is strong nowadays, the demand of various countries for petroleum resources is still strong. Nowadays, the production of land oil and gas resources is limited after long-term large-scale development, and the petroleum exploration and development to the ocean, particularly the deep sea, is a necessary trend. An underwater production system is important equipment for exploiting petroleum, the underwater production system is often used for controlling an exploitation process through various hydraulic control valves, and a hydraulic power station (installed on a water platform) is important equipment capable of providing hydraulic power sources for the various hydraulic control valves.

Currently, in the prior art, the publication No. CN204755435U discloses a hydraulic power device (i.e., a hydraulic power station) of an underwater production system, which includes an oil tank, at least one low-pressure pump circuit for outputting oil in the oil tank, at least one pressurizing circuit for increasing the oil pressure of the output oil, and at least one oil supply circuit for delivering the pressurized oil to the underwater production system; the low-pressure pump loop is communicated with the oil tank, and the pressurization loop and the oil supply loop are sequentially communicated with the low-pressure pump loop.

However, the hydraulic power device of the underwater production system still has the following defects:

when the hydraulic power device of the underwater production system is installed and used on an underwater platform, the hydraulic power device provides hydraulic power for the underwater production system (such as an underwater Christmas tree, an underwater wellhead connector and the like). The applicant finds for the first time in the industry that no matter how to design an underwater production system, all parts of the underwater production system are difficult to be guaranteed to obtain lasting hundreds of reliable seals, so that high-pressure combustible gas in the mining process easily overflows from the place with poor sealing and enters a hydraulic channel, the high-pressure combustible gas is further mixed into hydraulic oil, the hydraulic oil enters the oil and returns the oil, the combustible gas is carried into a hydraulic power device, the hydraulic power device is provided with explosion safety hazards, and the safety hazards are very dangerous for an offshore oil mining platform. At present, the safety hazard is not recognized by the technical personnel and the industry, and a technical scheme for solving the safety hazard is not provided.

Based on this, the applicant considered to design a more safe and reliable hydraulic power station.

Disclosure of Invention

Aiming at the defects of the prior art, the technical problems to be solved by the invention are as follows: how to provide a safer and more reliable hydraulic power station.

In order to solve the technical problems, the invention adopts the following technical scheme:

the hydraulic power station comprises a hydraulic power assembly, wherein the hydraulic power assembly comprises an oil tank, an oil well pump, an oil outlet pipeline and an oil return pipeline; the oil outlet pipeline is provided with an oil inlet end and an oil outlet end, the oil inlet end is communicated with the oil tank in a sealing mode, the oil well pump is installed on the oil outlet pipeline, and the oil outlet end is used for being connected with the hydraulic interface in a sealing mode; the oil return pipeline is provided with an oil return inlet end and an oil return outlet end, the oil return outlet end is communicated with the inside of the oil tank, and the oil return inlet end is used for being hermetically connected with an oil return interface; the method is characterized in that: the hydraulic power assembly is fixedly arranged in the bearing box body, and a door plate capable of entering and exiting the interior of the bearing box body is arranged on the bearing box body.

Compared with the prior art, the hydraulic power station has the advantages that:

1. the device is easier to arrange and install on the water platform quickly.

This technical scheme adopts the structure of "hydraulic power subassembly fixed mounting in the bearing box", like this, only need produce and assemble the bearing box on land, on offshore platform only need fixed the bearing box can, simplify hydraulic power subassembly's transfer and assembling process, promoted the assembly efficiency at offshore platform.

2. Is safer and more reliable.

The bearing box body can isolate the interior of the bearing box body from the exterior, and can play a certain role in explosion prevention and energy absorption during combustion and explosion, so that the bearing box body has better safety and reliability.
