Abstract

The invention discloses a pile foundation type reinforced concrete structure offshore oil platform. The pile foundation type reinforced concrete structure offshore oil platform comprises a deck platform that is of a single-layer structure and provided with flush drilling area deck platform and a process equipment facility area deck platform; the drilling area deck platform comprises two subsections disposed on the two sides of a drill conductor wellhead area, respectively; a steel track is arranged on an inner side of each drilling area deck platform subsection and projects from an upper surface of the drilling area deck platform subsection, and the two parallel steel tracks form land drilling rig slipping tracks. The pile foundation type reinforced concrete structure offshore oil platform has the advantages of good mechanical properties, convenient construction and the like by fully utilizing excellent stress tolerance of the reinforced concrete structure and the tensile capacity of a reinforcement material. Compared with a traditional jacket type offshore platform, the pile foundation type reinforced concrete structure offshore oil platform is low in structure construction cost and long in service life, and the strength, stiffness, workability, shock and collision property and durability of the offshore platform can be improved. Besides, the pile foundation type reinforced concrete structure offshore oil platform is applicable to oilfield development projects of different scales within a range of charted depths being 3m to 30m.

Description

technical field [0001] The invention belongs to the field of structural engineering in civil engineering, in particular to an offshore oil platform with a pile foundation type reinforced concrete structure. Background technique [0002] my country's coastal continental shelf sea area has rich oil and gas resources and marginal oil fields with relatively optimistic total reserves. With the continuous impact of low global oil prices and the high investment in offshore oil engineering development, the development and promotion of new offshore oil platforms has good market potential and development prospects. [0003] The traditional jacket-type offshore platform is a hollow steel pipe support and a multi-layer steel structure deck block structure, which has the characteristics of large steel consumption, self-heavy weight and high installation cost. During installation, the jacket is erected first, then pile legs are driven into the main pipe, and finally the deck modules are ...
