Abstract

The invention discloses a self-installation oil production platform. The oil production platform is a self-elevating-type platform and a crude oil tank is arranged in a platform body. A pipeline trestle is arranged on the stern portion of a main deck, a flare boom and a flare liquid separation tank are arranged on a starboard on the stern portion of the main deck, the bow portion of the main deck is provided with an emergency generator room, an emergency distribution room, a machine repair room, a hydraulic station, nitrogen generating equipment and a tool room, oil gas processing equipment and an oil conveying arm are arranged on the stern portion of a second-layer deck and the midship portion of the second-layer deck is provided with a hot oil boiler room, a transformer room, an oil production distribution room, a main distribution room, a main generator room and a natural gas generator room. The characteristics that an offshore drilling platform is movable and pile legs are in place are used in the self-installation oil production platform, the self-installation oil production platform integrates the functions of a fixed platform and the FPSO function, has the functions such as oil gas processing, crude oil storage and exportation, sewage treatment and life support, can be used repeatedly, greatly reduces the investment cost of oilfield development, and provides a technical support for marginal field development.

Description

technical field [0001] The invention relates to an oil production platform, in particular to a self-installation oil production platform. Background technique [0002] At present, the production operations of conventional offshore oilfields mostly use fixed platform type tests, and crude oil is transported to land terminals through submarine pipelines or received and processed by FPSO. This conventional oilfield development method has high investment, and the fixed platform cannot be moved to other oilfields after the oilfield is abandoned. The construction investment cost is high, and it cannot meet the development needs of marginal oilfields. Contents of the invention [0003] The invention provides a self-installation oil production platform with less investment that can meet the development needs of marginal oil fields in order to solve the technical problems in the known technology. [0004] The technical solution adopted by the present invention to solve the technic...
