Floating type production platform capable of taking well drilling and oil storage into consideration

Abstract

The invention discloses a floating type production platform capable of taking well drilling and oil storage into consideration. The floating type production platform comprises an octagonal-prism floating body with an octagonal horizontal section and a deck, wherein a ballast water tank, an oil storage tank, a production functional cabin, a well-drilling equipment cabin and a pump cabin; the deck is arranged on the floating body; an oil gas treatment system, well-drilling equipment and a positioning mooring system are arranged on the deck; and a moon pool is arranged on the floating type production platform. The floating type production platform has the functions of oil gas production, storage, transportation and well drilling, can be migrated and reused, is flexible and suitable for early trial production and well drilling development of an oil field with the water depth of more than 100 m, and can effectively reduce the economic risk of development of the oil and gas field. The floating type production platform has the same longitudinal and transverse size, has the size less than the longitudinal size of the boat type FDPSO, has basically same environmental force from each direction under the same environment condition and has the environmental force less than that of the boat type FDPSO under the transverse environment, adopts a multi-point mooring system, and can meet the requirements of platform well drilling and oil and gas production operation under the sever marine environment such as the South China Sea and the like.

Description

technical field [0001] The invention relates to a floating production platform with both drilling and oil storage in mind, in particular to a floating drilling oil storage platform for early oil test production in offshore oil fields. Background technique [0002] With the continuous expansion of the scale of human development of offshore oil and gas, the main battlefield of offshore oil and gas exploration and development has shifted to the deep sea. Due to the uncertainty of geological reservoirs and the high cost of traditional deep-water oil and gas development facilities, the development of deep-water oil and gas fields is highly risky. In order to reduce the economic risk of deep-water oil and gas field development projects, the new deep-sea oil and gas field development engineering facilities Floating Drilling, Production Storage and Offloading Unit (FDPSO) has become a research hotspot. A floating production system integrating heating, control, and living functions. ...

AI Technical Summary

Problems solved by technology

To meet the needs of oil production and drilling operations, the ship-type FDPSO must use a multi-point mooring positioning system or a dynamic positioning system to keep its position unchanged during the operation; the ship-type FDPSO has a large longitudinal length, and when subjected to lateral environmental load This feature limits the ship-type FDPSO to only be used in a few sea areas with good marine environmental conditions such as West Africa, and cannot be applied to oilfield development operations in sea areas with harsh marine environmental conditions such as the South China Sea.

The cylindrical FDPSO has a strong ability to resist environmental loads and can meet the needs of operations in the South China Sea where the environmental conditions are also relatively harsh. However, due to the shape of the hull, its hull processing and construction are relatively difficult
