Abstract

The invention provides a small semi-submersible production oil storage platform comprising an annular floating body, a plurality of vertical columns supported on the annular floating body, a main decksupported on the vertical columns, and a support truss supported on the bottom of the main deck and fixedly connected with the vertical columns. The support truss is an open structure with a bottom opening. The annular floating body and at least one vertical column are provided therein with oil storage tanks. The main deck is provided with a living module, a positioning mooring system, an oil andgas processing system, and an crude oil external transportation system. The oil and gas processing system is connected to an oil field through a vertical pipe. The oil and gas processing system and the crude oil external transportation system communicate with the oil storage tanks. The platform of the invention has the functions of crude oil production, storage and external transportation, and satisfies the development needs of a marginal field. The platform uses the main deck and the support truss, is simple in structure and has an obvious weight reduction effect. The support truss can resist the slamming load, improves the air gap of the platform, optimizes the platform scale, improve economical efficiency and saves cost.

Description

technical field [0001] The invention relates to a small floating production oil storage platform, in particular to a small semi-submersible production oil storage platform for deep water marginal oil fields. Background technique [0002] With the continuous improvement of exploration and development, there are fewer and fewer large-scale, integrated and high-quality oil reservoirs. In recent years, more and more marginal oil fields have been discovered in oil and gas exploration. Due to the low output of marginal oil fields, it is difficult to obtain economic efficiency by using traditional large-scale equipment and mining methods. How to effectively develop these marginal oil fields will be a key task in the development of offshore oil fields in the next few years. [0003] At present, in shallow waters such as the Bohai Bay, jack-up platforms have been used to realize the trial production of marginal oil fields and the development of oil and gas production. However, ther...
