Abstract

The invention discloses a deepwater floating type oil gas platform utilizing an underwater flexible storage device. The deepwater floating type oil gas platform comprises at least one upright post and a production group block fixed on the top of the upright post, wherein the underwater flexible storage device is arranged on the upright post and comprises an annular airtight storage tank and a plurality of storage single bodies; the storage single bodies are vertically arranged and fixedly connected in the annular airtight storage tank; the annular airtight storage tank is provided with a water pipe communicated with the outside; and each storage single body is provided with a flexible soft bag and an open protecting bush, and a medium loading-unloading pipeline connected with the production group block is arranged on the flexible soft bag and is fixed on the open protecting bush. The deepwater floating type oil gas platform is safe and environmentally friendly; by storing the media by virtue of the flexible soft bags, the separation between the media and water is realized, the volume utilization rate is high, and the cost is low.

Description

technical field

[0001] The invention belongs to the field of offshore oil and gas development, in particular to a deep-water floating oil and gas platform using an underwater flexible storage device. Background technique

[0002] There are two ways to carry out follow-up processing after crude oil is produced in offshore oil fields: 1) export it with submarine pipelines; 2) store it in an oil storage device and regularly transport it out with a shuttle tanker, which can be a fixed part of the production platform , can also be a single structure. If the production of an offshore oil field is not large enough, the cost of laying expensive submarine oil pipelines will outweigh the benefits. In this case, the only way to exploit it is to use some kind of low-cost but safe and reliable oil storage device.

[0003] Exactly where the oil storage unit is placed matters a lot. There are only three optional positions: 1) above the waterline and fixed in the upper layer of the platfo...
