Problems solved by technology

[0007] At present, most manufacturers of 300-foot jack-up drilling rigs often adopt the method of segmented loading in the process of lifting, locking, spud legs, and spud shoes. The improvement of speed and production efficiency is unfavorable, and it is not conducive to the control of loading accuracy

Embodiment Construction

[0022] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] During the loading process of the 300-foot jack-up drilling platform, the protruding connecting beam 2 at the top of the lifting and locking general section 3 affected the smooth entry of the spud leg and spud shoe general section 1 into the well. The fast carrying of the jack-up drilling platform is unfavorable.

[0024] After research, before the hoisting of the total section 1 of the spud leg and spud shoe, install the self-made hinge 4 and use it to tilt the lifting and locking section 3, so as to eliminate the interference between the top connecting beam 2 of the lifting and locking section 3 and the total section of the spud shoe. 1, and then carry out hoisting of the total section 1 of the spud leg spud shoe. When the spud shoe 11 falls to the well, stop the hoisting of the spud leg spud shoe general section 1, ...

Abstract

The invention discloses an integral building and carrying method for a drilling platform. The integral building and carrying method for the drilling platform comprises the following steps: step one, respectively and wholly assembling a lifting locking complete cross section and a spud leg and shoe, and the top portion of the lifting locking complete cross section comprises a protruding connecting beam; step two, arranging a hinge on the middle portion of the lifting locking complete cross section; step three, inclining the lifting locking complete cross section to a certain degree, enabling the connecting beam to be away from the spud leg and shoe, and further arranging the spud leg and shoe in a hanging mode; and step four, restoring the lifting locking complete cross section. In the process of constructing a 300 feet self-lifting type drilling platform, the integral building and carrying method for the drilling platform adopts a building and carrying method of restoring after obliquely arranging the lifting locking complete cross section, and is an innovative and novel building and carrying method of the 300 feet self-lifting type drilling platform construction technology.

Description

technical field [0001] The invention relates to a construction hoisting method, and more specifically, to an integral loading method of a drilling platform. Background technique [0002] The main structure of the existing platform is composed of the main body of the platform, the trunk area, pile legs, pile shoes, pile fixing room, second deck, helicopter platform, living building, engineering room and other structures. The main body of the platform is a box structure. Among them, the dimensions of spud legs and spud shoes are shown in the table below: [0003] Legs spud boots Leg length: 67.0m Stake shoe shape: square Leg diameter: φ3000mm Stake shoe length: 6.8m Leg wall thickness: 36, 30mm Spud shoe width: 6.8m Guide strip width: 700mm Stake shoe height: 1.65m Guide bar thickness: 36mm Side riser height: 0.65m Support ring beam spacing: 1000-2000mm [0004] The legs of this platform ...
