step 2, installing a simulation wellhead
Installing a centralizing sleeve on a supporting base, placing a test wellhead in the centralizing sleeve by using a hoisting lockset, installing a lower centralizing jackscrew and an upper centralizing jackscrew to centralize the test wellhead, and sequentially stacking and connecting a wellhead connector and a lifting short section on the test wellhead;
step 3, assembling the operation platform
Turning over the operation platform, mounting an upper support body on the lower surface of the operation platform, mounting a lower support body on the outer side of the fixed base, mounting an intermediate body into the lower support body by using a hoisting lockset, turning over the operation platform with the upper support body mounted, integrally hoisting, moving to the upper side of the intermediate body, adjusting the angle and the position of the operation platform to align the operation platform with the intermediate body, lowering the operation platform to enable the intermediate body to enter the upper support body of the operation platform and fix the upper support body, and mounting components such as a safety guardrail, a fixed pile, a fixed lifting lug and the like for the operation platform;
step 4, installing a service tool
Hoisting a service tool, moving the service tool to the upper part of a test wellhead, lowering the service tool, enabling the service tool to pass through a lifting short section and a wellhead connector and be placed in the test wellhead, then connecting a blind flange with the lifting short section, enabling a tool driving shaft to pass through the blind flange and be connected with the service tool through threads, hoisting a top hydraulic cylinder, moving the top hydraulic cylinder to the upper part of the blind flange, enabling a top hydraulic cylinder mandrel to be connected with the tool driving shaft, adjusting the extending distance of the hydraulic cylinder mandrel, enabling the top hydraulic cylinder to be in contact with the blind flange, and connecting the top hydraulic cylinder with the blind flange through bolts;
step 5, testing the underwater wellhead
And carrying out four tests such as an underwater wellhead stacking test, a service tool installation and recovery test, a pressure test, an inclination test and the like according to the test requirements.
