Abstract

The invention discloses a mechanical multifunctional underwater equipment installation and recovery device. The device comprises a main cylinder body, a driving shaft is sleeved with the upper portionof the main cylinder body, an upper port of the driving shaft is fixedly connected with an operation pipe column, and a lower port of the driving shaft is fixedly connected with a flushing pipe nipple; a pressing plate is clamped in an annular groove X of the driving shaft, and the pressing plate is fixedly connected with a driving sleeve downwards; the main cylinder body is sleeved with an innercavity of the driving sleeve; an isolation ring is sleeved with the space between the outer circumference of the upper portion of the driving shaft and the inner circumference of the upper portion ofthe main cylinder body; the lower middle portion of the outer circumference of the main cylinder body is in threaded connection with a centralizing ring, and a locking pin ring is arranged in an annular groove W formed in the outer circumference of the centralizing ring; the outer circumference of the upper end of the locking pin ring is sleeved with a clamping ring, and then the clamping ring issleeved with an annular groove Y in the lower section of the main cylinder body; anti-rotation keys are arranged in the upper annular groove and the lower annular groove of the outer circumference ofthe main cylinder body respectively. The device is compact in structure, diversified in function and good in adaptability.

Description

technical field [0001] The invention belongs to the technical field of offshore oil and gas drilling and production equipment, and relates to a mechanical multifunctional underwater equipment installation and recovery device. Background technique [0002] As the depth of offshore oil and gas production increases, it becomes more and more difficult to install, recover, and seal test the tubing hangers and hole protectors in the subsea tree system; affected by the operating water depth, these operations can only be performed in Remote control on the work platform. To complete the completion and workover of a single well, it is necessary to install tools, recovery tools, testing tools, and flushing tools, etc., resulting in a wide variety of supporting devices and complicated operating processes. Repeated lowering or recovery actions are required during the operation, which not only affects The operation efficiency is improved, and the cost of deep water operation is also incr...
