Problems solved by technology

This type of float-over installation of the wellhead platform requires an enlarged deck area and a large amount of steel, which also leads to the eccentricity of the jacket. Each wing covers a maximum of 20 wells, resulting in a maximum of 40 wells arranged on both wings.

Embodiment Construction

[0021] 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.

[0022] Such as figure 2 As shown, it is a top view of the offshore jacket production platform provided by the present invention. The offshore jacket production platform is an eight-leg jacket production platform, and the eight-leg jacket legs 1 are arranged in 2 rows and 4 columns, as shown in the figure row A, row B, column ①, column ②, column ③ and column ④. And the area between the jacket legs 1 of the adjacent row ① and ② is provided with a well slot area 2, and 60 well slots (more than 40 well slots, not marked in the figure) are arranged in the well slot area 2 . Such as figure 2 As shown, the well tank area 2 is set in the area between the jacket legs of row A and row B, so that the well tank of the floating towing platform is arranged between the working points of the jacket structure, ...

Abstract

The invention discloses an offshore jacket production platform. The offshore jacket production platform is a six-leg jacket production platform or an eight-leg jacket production platform. Jacket legs of the six-leg jacket production platform are arranged in two rows and three lines. The jacket legs of the eight-leg jacket production platform are arranged in two rows and four lines. Well slot areas are arranged among the jacket legs in adjacent lines, and a plurality of well slots are formed in the well slot areas. The offshore jacket production platform can meet well drilling requirement of more than forty well slots, the problem of jacket eccentricity is solved, and deck area of the offshore jacket production platform is saved, so that steel is saved, and engineering investment cost of the platform is reduced.

Description

technical field [0001] The invention relates to an offshore jacket production platform. Background technique [0002] With the in-depth exploration and development of offshore oil and gas fields, offshore oil platforms are developing in the direction of large-scale, intensive, and deep water, and the overall weight of the upper part of the platform is also increasing. Large-scale cranes (floating cranes) can no longer fully Meet the development needs of oil and gas fields, especially the overall installation of 10,000-ton large blocks. Floatover technology can realize the overall installation of 10,000-ton large-scale blocks to make up for the insufficient capacity of floating crane resources to install large blocks. [0003] The wellhead area of ​​the conventional float-over installation platform is arranged on the two wings of the platform. The loading block barge enters the ship along the working point of the jacket parallel to the notch. The required deck area is increa...
