Problems solved by technology

The practical engineering application shows that as the water depth increases, the environmental load becomes larger, and the way of storing oil on the water surface will lead to a large increase in the steel consumption of pile legs and foundations, and the requirements for the lifting system will also increase accordingly, making the platform investment very large. huge
At the same time, due to the erosion of the seabed current, the stability of the platform will be affected.

Abstract

The invention provides a mat-assisted driving movable platform comprising an upper platform, a plurality of pile legs and a bottom platform foundation. The upper portion of every pile leg is connected with the upper platform. The lower portion of every pile leg is inserted into the bottom platform foundation and extends out of the other end of the bottom platform foundation. The bottom platform foundation is a mat foundation with skirt plates. A body of the bottom platform foundation is provided with an oil store inside. The mat-assisted driving movable self-installed platform is a novel engineering facility for the development and research of offshore marginal oilfields, is applicable to movable reusable facilities different in water depth and seabed conditions and cost control in the development and offshore installation process of facilities, is available for the development of marginal oilfields, and is effective for controlling the risk in the development of marginal oilfields.

Description

technical field [0001] The invention relates to a cushion-sinking-assisted pile-inserting movable platform, in particular to a cushion-sinking-assisted pile-inserting type underwater oil storage production platform with a movable self-installation function that can be applied to the field of marine engineering at a water depth of 60 to 100 meters . Background technique [0002] For the development of offshore marginal oilfields, if conventional technology and equipment are used, it is difficult to obtain a satisfactory return on capital due to the limitations of uncertain factors such as reserves and geological reservoir conditions. The development of marginal oilfields can be realized through the mobility and reuse of development facilities, and the cost control of the offshore installation process of development facilities, which can effectively control the risk of marginal oilfield development. [0003] At present, my country only has experience in the design and applica...
