Abstract

The invention discloses a three-dimensional super-long rigid connection pipeline system with buoyancy devices. The three-dimensional super-long rigid connection pipeline system is used for connecting a wellhead Christmas tree and a manifold, and comprises a connection pipeline body, quick connectors arranged on two end sides of the connection pipeline body, the multiple buoyancy devices arranged on the connection pipeline body and a plurality of vortex-induced vibration suppression devices arranged on the connection pipeline body. The two quick connectors are correspondingly connected with the wellhead Christmas tree and the manifold, and the connection pipeline body is formed by combining and changing a plurality of straight pipe nipples and a plurality of elbows at different positions in a three-dimensional space. According to the three-dimensional super-long rigid connection pipeline system, different assemblies of the whole system are designed, the requirements for various wellhead oil reservoir characteristics, spatial arrangement and the like are met, and the super-long rigid connection pipeline system which is provided with the vortex-induced vibration suppression devices and the buoyancy devices and is located in the three-dimensional space can greatly guarantee safe development and production of a deepwater oil and gas field; and the three-dimensional super-long rigid connection pipeline system with the buoyancy devices has the advantages of reliable structural strength and fatigue life, high cost performance and convenience in installation.

Description

technical field [0001] The invention relates to the technical field of offshore oil engineering, in particular to a three-dimensional ultra-long rigid connection pipeline system with a buoyancy device. Background technique [0002] Deepwater marine engineering mostly adopts "underwater facilities + connecting pipelines + manifolds + submarine pipelines + floating structures + external pipelines + land terminals" or "underwater facilities + connecting pipelines + manifolds + submarine pipelines + floating structures + export ship" development mode, the underwater wellhead oil and gas resources have high temperature and high pressure characteristics, need to be treated with the help of the manifold, then pass through the underwater pipeline to the floating structure, and connect the underwater wellhead and the pipeline system between the manifold, which needs to withstand high temperature and high pressure Loads such as combined action of waves and currents are the key compone...
