Description

technical field [0001] The invention relates to the technical field of offshore oil and gas drilling, in particular to a device and method for an integral tensile simulation experiment of a deep-water surface conduit feeding tool. Background technique [0002] Deepwater drilling generally refers to drilling with a depth of more than 900 meters in offshore operations. During the process of deepwater drilling in the ocean, due to the low strength of the shallow undiagenetic strata on the surface of deepwater drilling, it is prone to collapse. The deepwater surface conduit is installed during the entire deepwater oil well construction process. The first layer of casing, which provides structural support for all subsequent casings and wellhead equipment, is the "throat" of deepwater drilling. [0003] In the process of using the deep-water surface conduit-running tool to carry out the surface conduit spraying operation, the deep-water surface conduit-running tool is often subjec...
