Production and mooring system for sea floating type oil extraction platform and operating method thereof

Abstract

The invention discloses a production and mooring system for a sea floating type oil extraction platform, which includes an in-water production platform, an in-water production system, rigid stand pipes, tension mooring devices, in-water pile foundations and flexible jumper pipes, wherein the in-water production system includes in-water oil extraction equipment and a manifold center; the in-water production platform includes in-water oil extraction platforms and a manifold platform that are all positioned 50-300 m below the sea level; the at least three in-water oil extraction platforms are diffused and placed around the manifold platform. According to the invention, as the single production platform in the prior art is designed into at least three in-water oil extraction platforms and one manifold platform, the problem that the in-water oil extraction equipment, the in-water manifold and the in-water manifold center cannot be distributed in the prior art can be solved, and the in-water manifold and the oil extraction equipment can be arrayed separately, so that the design for the platforms is more professional, and optimized layout of the positioning of the sea floating type oil extraction platform and all functions of the in-water production system can be realized.

Description

technical field

[0001] The invention belongs to the field of marine engineering equipment, and relates to a production and mooring system and a working method of a floating oil production platform on the sea surface used in an extremely deep sea environment. Background technique

[0002] my country's extremely deep water areas in the South China Sea (water depth greater than 2,000 meters) are rich in oil and gas resources, but currently my country only has a full set of capabilities for exploration, development and production of oil and gas fields in water depths within 300 meters.

[0003] The technical difficulties faced by the development of oil and gas fields in the extremely deep water environment of the South China Sea mainly include the following aspects: first, the huge water depth leads to high requirements for the design, manufacture, installation and use of marine engineering equipment; second, the extremely deep sea environment is harsh, such as typhoon Invasion ...
