Embodiment 1

[0017] Embodiment 1: as figure 1 As shown, the A-type drilling derrick for the construction of double two-story platforms is composed of crown block 1, derrick main body 2, high two-story platform 3, derrick accessories 4, low two-story platform 5, and herringbone frame 6. The crown block 1 is connected to the main body 2 of the derrick, the main body 2 is connected to the high second-story platform 3, the derrick attachment 4, the low second-story platform 5 and the gable 6, and the gable 6 is connected to the drilling floor 7; L1 is the low second-floor platform 5 to The vertical distance from the drill floor surface 7, L2 is the vertical distance from the high-level second floor platform 3 to the drill floor surface 7, and L3 is the vertical distance from the crown block 1 to the drill floor surface 7.

[0018] In order to solve the problem of many times of connecting and unloading columns and low efficiency during the drilling construction of A-type drilling rig derrick wi...

Abstract

The invention discloses an A-shaped drilling rig derrick with double racking platforms for construction, and belongs to the technical field of drilling rig derricks. A crown block platform is connected with a derrick main body; the derrick main body is connected with a high-position racking platform, a derrick attachment, a low-position racking platform and an A-frame; the A-frame is connected with a drill floor surface; L1 is a perpendicular distance from the low-position racking platform to the drill floor surface, L2 is a perpendicular distance from the high-position racking platform to the drill floor surface, and L3 is a perpendicular distance from the crown block platform to the drill floor surface. The A-shaped drilling rig derrick with double racking platforms for construction, disclosed by the invention, has the benefits as follows: 1. after one racking platform is additionally arranged, the double-racking-platform structure is used for storage and bearing of a stand column, so as to realize safe operation to a stand column formed by connecting four single stand columns; 2. the drilling rig derrick is used for drilling deep wells and extremely-deep wells, and can reduce stand column connecting and dismounting times, increase the downwards-drilling speed, improve the drilling efficiency, and shorten the drilling cycle; 3. other auxiliary facilities of the drilling rig can be fully used, the drilling rig derrick is reliable, and can save the capital.

Description

technical field [0001] The invention relates to an A-type drilling rig derrick for double-two-story platform construction, and belongs to the technical field of drilling rig derricks. It relates to an A-type drilling rig derrick that increases the number of two-story platforms, increases the operating space, and can operate more single-connected columns. Background technique [0002] The derrick of a drilling rig is a metal truss structure with a certain height and span. It is an important part of the drilling rig. The crown block is placed, the swimming system is suspended, and the drilling tool is suspended to perform operations such as tripping drill pipes, running casing, and dealing with downhole accidents, and is subjected to various operating loads. [0003] A-type drilling rig derrick is a kind of derrick. The current A-type drilling rig derrick only has a second-story platform for storing columns and bearing the weight of the columns. The space provided by the derr...
