Removable self-installing type drilling and production processing oil storage platform

Abstract

The invention discloses a removable self-installing type drilling and production processing oil storage platform. The drilling and production processing oil storage platform comprises an upper platform, a plurality of spud legs and a plurality of bottom platform bases, wherein numbers of the spud legs and the bottom platform bases are equal, the lower end of each spud leg is connected with each bottom platform base, the upper end of each spud leg is connected with the upper platform, and the spud legs and the upper platform can relatively move along the vertical direction. The removable self-installing type drilling and production processing oil storage platform can achieve recycle and self-installing of all platform facilities for marginal oil field development, reduces investment of engineering facilities, reduces construction cost and dependency on construction equipment, can effectively control marginal oil field development risk, and has wide application prospect for the marginal oil field development.

Description

Technical field [0001] The invention relates to a movable and self-installing drilling, production and processing oil storage platform. Background technique [0002] At present, the discovery of large-scale offshore oilfields is decreasing, and a large part of the newly discovered oilfields belong to the category of marginal oilfields. For the development of offshore marginal oil fields, it is difficult to obtain a satisfactory rate of return on funds if conventional technologies and equipment are used. Conventional development mode requires multiple platform facilities with different functions to realize the development of offshore oilfields, such as the development mode that combines drilling ships, wellhead platforms and central processing platforms, the development mode that combines wellhead platforms with drilling rig modules and central processing platforms, or A development model that combines a drilling ship with a central processing platform with a wellhead. The fixed ...

For the development of offshore marginal oil fields, if conventional technology and equipment are used, it is difficult to obtain a satisfactory return on capital

The conventional development mode requires multiple platform facilities with different functions to realize the development of offshore oilfields, such as the development mode combining drilling ships, wellhead platforms and central processing platforms, the development mode combining wellhead platforms with drilling rig modules and central processing platforms, or The development mode of drilling ship combined with the central processing platform with wellhead, the fixed platform facilities cannot be reused, and the offshore installation requires the use of large construction equipment, which is expensive

At present, a new type of mobile self-installation production and storage platform can replace the central processing platform. Its self-installation function and reusable features can effectively reduce the development cost of marginal oil fields, but it still needs to cooperate with the drilling ship and the wellhead platform or belt. The wellhead platform combined with drilling rig modules, the non-reusability of the wellhead platform and the dependence on construction tools for installation are still important factors restricting the development of marginal oilfields
