Example Embodiment

[0018] The deep-water gravity screw automatic connector is composed of a screw power head 1, a screw motion sub-section 2, a connecting shell 3, an upper limit sleeve 4, a lower limit sleeve 5, a disc spring 6 and an end cap 7, and the lower end thread of the screw motion nub 2 A connecting housing 3 is installed, a screw power head 1 is installed in the spiral motion nipple 2, a riser 8 is threaded on the top of the spiral power head 1, and an end cap 7 is installed on the top thread of the spiral motion nipple 2. The end cap 7 and the riser tube An upper limit sleeve 4 is installed between 8 and the screw power head 1 through a sealing ring 9, and the end cover 7 is slidingly connected with the riser 8, the screw power head 1 and the upper limit sleeve 4. The sealing ring 9 is installed on the upper part of the upper limit sleeve 4. The sealing ring 9 can prevent impurities in the ocean from entering the tool, avoiding the normal operation of the tool and polluting the interna...

Abstract

The invention relates to a deep-water gravity type screw automatic connector, which belongs to the technical field of offshore oil drilling and production tools. It is composed of a screw power head, a screw motion short joint, a connecting shell, an upper limit sleeve, a lower limit sleeve, a disc spring and an end cover; a connecting shell is threaded on the lower end of the screw motion short joint, and a screw power head is arranged in the screw motion short joint ;A disc spring is installed in the connecting shell under the screw power head through the lower limit sleeve. The overall design of the connector is ingenious, and it can cope with the fluctuating load caused by the fluctuation of wind, wave and current during the construction process and the impact load caused by the lowering of the pipe string; it has the characteristics of simple structure, convenient operation, strong adaptability and low cost; it is especially suitable for deepwater risers and wellheads Connect to use.

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...
