The invention discloses a deepwater semi-submersible type production platform. The deepwater semi-submersible production platform comprises an upper module and a lower floating body for supporting theupper module, the lower floating body comprises four filleted stand columns and an annular floating box. The four stand columns are arranged in a square shape, and the bottoms of the stand columns are communicated through an annular buoyancy tank. The upper module is matched with each stand column through two fulcrums, and the fulcrums are arranged on the edges of the stand columns, so that the tops of the stand columns are exposed outside. A condensate oil tank is arranged in each stand column; MEG cabins are arranged in the three stand columns and comprise the poor MEG cabin and the rich MEG cabin. And an SLOP cabin is arranged in the other stand column and comprises a cabin A and a cabin B which are adjacent to each other and are communicated with each other through a pipeline. The semi-submersible production platform has the functions of production treatment, power, life support and condensate oil storage, has feasibility, and can be used for development of deepwater large naturalgas fields by being combined with an underwater production system.

    本发明公开了一种深水半潜式生产平台。所述深水半潜式生产平台,包括上部组块和支撑上部组块的下浮体;下浮体包括四个倒圆角的立柱和环形浮箱;四个立柱呈方形布置,立柱的底部通过一环形浮箱连通;上部组块与每个立柱通过2个支点配合,支点设于立柱的边缘,使立柱的顶部裸露于外。每个立柱内设有凝析油舱;3个立柱内均设有MEG舱,包括贫MEG舱和富MEG舱;剩余的1个所立柱内设有SLOP舱,包括相邻的A舱和B舱,通过管道连通。本发明半潜式生产平台具有生产处理、动力、生活支持和凝析油存储的功能,且具有可实施性,通过与水下生产系统进行组合,可以用于深水大型天然气田的开发。
