Deepwater pipe cable connection protection device for offshore oil drilling and use method

Abstract

The invention relates to the field of offshore oil and gas engineering, in particular to a deepwater pipe cable connection protection device for offshore oil drilling and an application method. According to the technical scheme, a self-breaking protection connector is connected between a deepwater production facility and a deepwater pipe cable, the self-breaking protection connector comprises an inner connector and an outer connector, the tail end of the deepwater pipe cable is connected with the outer connector, the upper end of the deepwater production facility is connected with the inner connector, and a weak protection block is arranged at the tail end of the inner connector; the inner joint is matched with a trapezoidal limiting hole formed in the inner end of the outer joint, and an inner conveying pipe is arranged in the outer joint and the inner joint; and an inner pipe self-breaking joint is arranged on the inner conveying pipe. The device has the advantages that after deepwater operation is completed, the self-breaking protection connector and the inner pipe self-breaking connector are disconnected through mechanical traction, the deepwater pipe cable and a deepwater production facility can be disconnected, the deepwater pipe cable can be recycled, the deepwater production facility is left on the seabed, manual participation is little, safety and reliability are achieved, the inner pipe self-breaking connector and the inner pipe self-breaking connector can achieve self-sealing, and the service life of the deepwater pipe cable is prolonged. The seawater pollution is avoided.

Description

technical field [0001] The invention relates to the field of offshore oil and gas engineering, in particular to an offshore oil drill using a deep-water pipe cable connection protection device and a method of using the same. Background technique [0002] In the development of offshore oil and gas fields, umbilicals are called the "lifeline" of offshore oil and gas fields, and play a key role in the development, production and transportation of offshore oil. Marine flexible umbilicals mainly include flexible hoses, umbilicals, etc. As the development of offshore oil and gas resources continues to move towards deep water areas, the development mode of underwater production systems determines that a large number of deep water umbilicals will be used. However, due to the late start of the development of offshore oil and gas development projects in my country and the relatively backward engineering equipment and technology, the laying and installation of deepwater cables and oth...

AI Technical Summary

Problems solved by technology

However, due to the late start of the development of offshore oil and gas development projects in my country, and the influence of factors such as relatively backward engineering equipment and technology, the laying and installation of deep-water pipelines and cables started late, and there is a huge gap with foreign countries in terms of design and construction level. Therefore, there is an urgent need to develop related equipment for the installation and construction of deepwater pipe cables
