Embodiment 1

[0035] Example 1, refer to Figure 1-10 , a kind of offshore oil drill mentioned in the present invention adopts deep-water umbilical connection protection device, including winch 8, deep-water umbilical cable 9, and deep-water umbilical cable 9 is sent to the seabed through winch 8, and the deep-water production facility 11 on the seabed is connected, A self-breaking protective joint 10 is connected between the deepwater production facility 11 and the deepwater cable 9, and the self-breaking protective joint 10 includes an inner joint 2 and an outer joint 4, wherein the end of the deepwater cable 9 is connected to the outer joint 4, and the deepwater production The upper end of the facility 11 is connected to the inner joint 2. The end of the inner joint 2 is provided with a raised weak protection block 6, which cooperates with the trapezoidal limit hole 4.8 provided at the inner end of the outer joint 4. The inner joint 2 and the outer joint 4 is the interference assembly, u...

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...
