The wellhead frame is composed of a suction cylindrical base plate, a water-resistant casing guide column, a water-resistant casing, and an upper block. Bebon Machining can customize production according to customer needs and drawings.
The feature of the wellhead frame is that the riser casing replaces the original jacket, which can not only play the role of the riser casing, but also replace the traditional jacket as the support of the upper block; the guide column of the riser casing can After the water-resistant casing is driven in, it can be disassembled, and then reinstalled into the upper block, so as to realize the multiple utilization of the water-resistant casing guide column.
The advantage of this wellhead frame structure is that the water-resisting casing replaces the original jacket structure, which reduces the amount of steel used in the project, and can be directly installed offshore through the hook or small floating crane on the drilling ship; The leveling operation is carried out at the same time as the base plate is lowered, thereby simplifying the offshore installation procedure, achieving the purpose of shortening the offshore installation period and reducing costs.
