Problems solved by technology

[0003] At present, most of the underwater connectors are hydraulically controlled, but for the deep water environment, higher requirements are placed on the hydraulic system, resulting in high cost of the connector, relatively complicated operation, and low ability to respond to unknown marine environments , therefore, it is necessary to develop an underwater connector with simple structure, easy operation and strong adaptability

Abstract

The invention relates to a deep water gravity type spiral automatic connector and belongs to the technical field of offshore oil drilling tools. The deep water gravity type spiral automatic connector comprises a spiral power head, a spiral motion pup joint, a connecting shell, an upper limit sleeve, a lower limit sleeve, a disc spring and an end cover, wherein the connecting shell is mounted at the lower end of the spiral motion pup joint in a threaded manner, and the spiral power head is arranged in the spiral motion pup joint; the disc spring is mounted in the connecting shell below the spiral power head through the lower limit sleeve. The deep water gravity type spiral automatic connector is ingenious in overall design, capable of dealing with fluctuation load caused by wind wave flow fluctuation and the impact load of string setting, simple in structure, convenient to operate, high in adaptability, low in cost and especially applicable to deep marine risers and wellhead connection.

Description

technical field [0001] The invention relates to a deep-water gravity type screw automatic connector, which belongs to the technical field of offshore oil drilling tools. Background technique [0002] With the depletion of onshore oil and gas resources and the prominent contradiction between oil and gas supply and demand, offshore oil and gas exploration and development has become the focus of attention of various countries. In the marine underwater environment, especially when the water depth exceeds a certain depth, it is beyond the range that can be handled manually. For operations such as oil and gas exploitation and well maintenance, it is necessary to realize the connection or separation of the riser and the wellhead components, which is very important for the ocean. The exploitation of oil and gas equipment is of great significance. [0003] At present, most of the underwater connectors are hydraulically controlled, but for the deep water environment, higher requireme...
