Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings, but the present invention is not limited to the following embodiments.

[0025] Such as figure 1 , figure 2 and image 3 As shown, the movable self-installation platform provided by the present invention includes an upper production platform 1, 4 truss-type legs 2 and a bottom platform foundation 3 with skirt plates; the bottom of the legs 2 is fixedly connected to the bottom platform foundation 3, and the pile The top of leg 2 is connected with upper production platform 1 by rack-and-pinion lifting mechanism (not shown in the figure), so that the height of upper production platform 1 can be adjusted according to water depth; the cross section of upper production platform 1 is a rectangle, its Sewage settlement chamber 5, production module, power module and living module are arranged on the upper part. During towing, the upper production platform 1 can provide buoyanc...

Abstract

The invention discloses a movable self-installation platform. The self-installation platform comprises an upper production platform, a bottom platform foundation and at least three pile legs, wherein upper portions of the pile legs are connected with the upper production platform, lower portions of the pile legs are connected with the bottom platform foundation, and an oil storage compartment is arranged inside a body of the bottom platform foundation. The movable self-installation platform has the advantages that the platform is movable and can be recycled, an investment of a set of engineering facilities is shared by a plurality of small oil fields, and the development benefit of the small oil fields is improved; the platform is comprehensive and multifunctional, production, oil storage and exporting can be integrated, and the problems that support of development of the small marginal oil fields by peripheral facilities is saturated or no support exists are solved; self-installation can be achieved, dependence on large constructing ships is reduced, the flexibility of construction selection is improved, the construction cost is reduced, and meanwhile, pressure caused by overload of construction machines and tools on engineering progress is relieved.

Description

technical field [0001] The invention relates to a movable self-installation platform. Background technique [0002] As the history of petroleum resources development has become longer and longer, the discovery of large-scale integrated oilfields has become less and less, and a large part of newly discovered oilfields belong to the category of marginal oilfields. For the development of marginal oilfields, especially 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 des...
