FRAME OF THE WELLHEAD EQUIPMENT ASSEMBLY Russian patent published in 2022 - IPC E21B33/35 E21B41/08 

FIELD: mining industry.

SUBSTANCE: invention relates to a device used in the operation of offshore and onshore wells, and can be used in the construction of a well, for example, underwater. The proposed frame of the wellhead equipment assembly consists of the base of the frame of the wellhead equipment assembly and the frame elements representing at least one of: the frame of the wellhead equipment, the frame of the fitting module, the frame of the control module, the frame of the exterior panels. In this case, the base of the frame of the wellhead equipment assembly is a welded structure in which an intermediate contour and elements for attaching the remaining parts of the frame of the wellhead equipment assembly are welded to the support contour through spacers. Moreover, the design of the frame of the wellhead equipment assembly is made in such a way that the frame of the fitting module, the frame of the fountain armature, the frame of the control module and the frame of the exterior panels have the ability to be bolted to the base.

EFFECT: reduction in the probability of damage to the frame of the wellhead equipment assembly during transportation, as well as a reduction in the number of fitting and lining operations during the manufacture and assembly of the wellhead equipment assembly frame and a reduction in the distortion of the spatial structures of the wellhead equipment assembly frame.
