Deep water pipeline multi-circuit bridging system and testing and installing method thereof

Abstract

The invention discloses a deep water pipeline multi-circuit bridging system and a testing and installing method thereof. The deep water pipeline multi-circuit bridging system comprises a seabed manifold, an underwater electric distribution assembly, a first underwater Christmas tree, a second underwater Christmas tree, a first underwater umbilical cable terminal and a second underwater umbilical cable terminal, wherein the seabed manifold, the underwater electric distribution assembly, the first underwater Christmas tree, the second underwater Christmas tree, the first underwater umbilical cable terminal and the second underwater umbilical cable terminal are connected through a hydraulic bridging wire and a water and gas injection pipeline. The hydraulic bridging wire comprises male connector terminals and female connector terminals matched with the male connector terminals. The testing and installing method of the deep water pipeline multi-circuit bridging system includes the following steps that a leakage test and a flushing test are performed on the male connector terminals and the female connector terminals, after the tests are finished, the water and gas injection pipeline and the hydraulic bridging wire are moved underwater, and the water and gas injection pipeline and the hydraulic bridging wire are installed between underwater equipment respectively through the ROV operation. According to the deep water pipeline multi-circuit bridging system and the testing and installing method thereof, fast connecting and disconnecting between the underwater equipment can be achieved, it is ensured that all key parts and moving portions can be recycled, and the stopping and connecting states of an ROV can be safe and reliable.

Description

Technical field [0001] The invention relates to the technical field of offshore oil and gas exploitation, in particular to a deep-water pipeline multi-circuit bridging system used for oil and gas drilling and production manifold connections and a test and installation method thereof. Background technique [0002] In the hydraulic pipeline or the water pipeline, it is often encountered that the pipeline is connected. In the process of connecting or disconnecting the pipeline, how to ensure the sealing degree of the pipeline and optimize the connection method of the connection joint is a technical problem. Especially in the middle of the ocean environment, the technical difficulty of drilling oil production on the ocean is much greater than that of land drilling. In order to adapt to the specific marine working environment, there are corresponding technical requirements for the supporting oil drilling equipment. The most basic technical requirement is that no leakage is allowed. ...

AI Technical Summary

Problems solved by technology

[0005] The disadvantages of the existing technology are: the existing quick-installation joints cannot take into account the effect of instant cut-off and fast clamping, and the clamping method is relatively traditional, and threaded connection is mostly used, and specific tools are required for disassembly or connection. It is very troublesome to operate, which makes the operator time-consuming and laborious, and the pipeline cannot be connected in time and quickly during the operation process. At the same time, the structure is relatively complicated and there are many components, so that the sealing performance cannot be guaranteed, and the existing jumper wire , the connection is cumbersome and the operation is inconvenient
