Description
This invention relates to a derrick structure.
Due to the recent rapid industrialization, the use of resources such as oil has skyrocketed, and the stable production and supply of oil is becoming a very important issue. However, the oil field in the continental or coastal waters has already been drilled. In recent years, interest has been focused on the development of a deep-sea deep-sea oil field. Drilling is generally used to drill deep-sea oilfields.
Drill ship is an offshore structure that is equipped with advanced drilling equipment and is built in a shape similar to that of a ship so that it can be sailed by its own power. It is capable of collecting raw oil or gas in deep sea area where an offshore platform can not be installed, It is advantageous that the drilling can be terminated and the drilling can be carried out by moving to another point.
Such drillings include Derrick, which has a Moonpool structure in a vertically penetrating form and is located above the drum and has drilling rigs. Hereinafter, the process of drilling the bottom of the drill ship will be described.
First, the drill ship uses its own power to move to the drilling area and drives a Dynamic Positioning System (DPS) using a plurality of thrusters to maintain the position.
Thereafter, the drill bit is connected to a drill pipe by a drill bit, and a plurality of drill pipes are connected by a sufficient length by using a Hoisting System and a Handling System provided in Derrick, And the drilling pipe is rotated through a rotating system to form a borehole.
Once drilling is completed, Derek picks up the drill pipe, installs the casing pipe on the borehole, and performs the cementing process to fill the concrete between the casing pipe and the borehole. The drilling operation used and the casing and cementing work for installing the casing pipe are repeatedly performed to maintain the shape of the borehole having a certain depth.
When the casing pipe is installed enough to prevent the borehole from falling down, BOP (Blow Out Preventer) is connected to the riser to be connected to the borehole. In this case, the inside of the riser becomes the path of movement of the drill pipe and casing pipe.
However, lubrication and cooling of the drill bit in the drilling process, and processing of the crushed material such as rock mass produced in the borehole are required. Therefore, the drill feeds the mud to the inside of the drill pipe so that the mud is discharged at the end of the drill bit, and after the mud performs lubrication and cooling of the drill bit, (Mud Circulation System) is used. The recovered mud is re-used after the pulverized material is filtered.
The drillship repeatedly performs drilling, casing and cementing operations until the drill bit reaches the well, while driving this mud circulation system. In this case, as the diameter of the casing pipe used in the casing work becomes smaller, Drilling can be implemented continuously by replacing small drill bits.
As such, the drill rig has a system for installing and using pipes and risers, a system using a mud, and the like. In order to smoothly perform drilling work using such a system, a drill hole structure, a derrick structure, and a load structure Is required to be disposed within a certain space, so that research and development are being continuously carried out as a result of a high technological power being required.
However, the top drive for assembling the drill equipment needs to be adjusted in the vertical position on the derrick, and the top drive is moved up and down by adjusting the length of the fast line wound on the derrick.
On the other hand, in order to adjust the length of the fastra, the fast line is wound and loosened, and the fast line reaches the derrick structure, so that the fast line may be worn or the derrick structure may be damaged.
The object of the present invention is to provide a derrick structure capable of reducing wear of the fast line and preventing damage to the derrick.
The derrick structure according to an embodiment of the present invention includes a fast line wound on an upper portion of a derrick, both ends of which are positioned on both sides to adjust the height of the top drive; And a bumper portion provided on the derrick, the bumper portion being rotatably provided on the path of the fast line to prevent abrasion of the fast line.
Specifically, the bumper portion includes a roller member; And a support member to which the roller member is rotatably provided.
Specifically, the roller member is characterized in that a plurality of roller members are arranged in a row in an up-and-down direction so that their rotational axes are shifted corresponding to the inclination angles of the fast lines.
Specifically, the support member is provided at both ends of the roller member so as to support both ends of the roller member.
The derrick structure according to the present invention reduces abrasion by reducing the friction generated on the fast line due to rotation of the roller member in conjunction with fastening and unwinding of the fast line and prevents the fast line from coming into direct contact with the derrick, And it is easy to separate the support member and the roller member from each other, so that the maintenance can be facilitated.
