项目概况
BD (略)-1 gas field group includes BD (略)-1, Lingshui (略)-1 and Yongle 8-1 gas fields, are all located in deep water with (略)~(略) water depth. Production fluid of BD (略)-1 gas field group is rich in CO2. As a conclusion of basic design, the development consists of two sets of subsea production systems (SPS), i.e. BD (略)-1 SPS and Lingshui(略)-1/Yongle 8-1 SPS, including subsea wells, manifolds, PLEMs, PLETs, flowlines, pipeliens, umbilicals and other subsea facilities will be tied back to a new production central processing platform BD(略)-1 CEPA, which will be built in the shallow water area with (略).2m water depth. The dry gas and condensate oil processed on the BD(略)-1 CEPA platform, and then exported by a (略)in export subsea pipeline from BD (略)-1 CEPA to onshore terminal. The dry and dense CO2 will be transported to the BD (略)-3 subsea well through a (略).7km subsea pipeline and injected underground for storage.The SPS of BD (略)-1 includes (略) subsea production wells and will be controlled on BD(略)-1 CEPA. Lingshui(略)-1/Yongle 8-1 SPS includes 9 subsea production wells and will be controlled on existing DeepSea No.1 SEMI. BD (略)-3 includes 1 subsea CO2 injection well. One floating offshore wind turbine BD(略)-1 FOWT will be built near the BD (略)-3 subsea CO2 injection well to control the BD (略)-3 subsea well through one subsea umbilical and provide power to the BD(略)-1 CEPA platform through one seubsea cable.The production fluids from the (略) wells of BD(略)-1 are gathered and transported to the BD(略)-1 CEPA in shallow water. Production fluid from LS(略)-1 wells is routed through to YL8-1, the combined flow is transported BD(略)-1 CEPA in shallow water. After (略), Lingshui(略)-1/Yongle 8-1 system will be connected to the existing LS(略)-2 East 3 Manifold and production fluid will be transported in the reverse direction to existing DeepSea No.1 SEMI via LS(略)-2 SPS. The subsea pipeline from YL8-1 to BD(略)-1 CEPA will be connected to BD(略)-1 SPS and used to transport dry gas from BD(略)-1 CEPA to BD(略)-1 SPS to maintain the minimum flow rate of the pipeline from BD(略)-1 SPS to BD(略)-1 CEPA to meet flow assurance requirement.
