Water bottom adhesion type self-stabilization oil and gas transport pipe

Abstract

The invention relates to a water bottom adhesion type self-stabilization oil and gas transport pipe. The water bottom adhesion type self-stabilization oil and gas transport pipe is a combined type pipe formed by arranging a concrete interlayer between a streamline type outer layer pipe wall and an inner pipe. The streamline type outer layer pipe wall is integrally formed by extending a base plateupwards to an arc top through two side wings. The cross section of the streamline type outer layer pipe wall is a multi-curve streamline type cross section. The gravity center of the cross section ofthe combined type pipe is located in the middle of the bottom of the pipe, so that a tumbler type self-stabilization force-bearing structure form is formed. The combined type pipe is laid on a rock-soil layer at the water bottom, and the base plate is in close contact with the rock-soil layer. According to the water bottom adhesion type self-stabilization oil and gas transport pipe, the multi-curve streamline cross section form is adopted; the ocean current effect to which the pipe is subjected is small; the gravity center of the cross section is low; the bottom of the combined type pipe is inclose contact with the water bottom; the pipe is laid at the water bottom in an adhering manner; the pipe bears the force reasonably; the risk of pipe resonance is avoided; and the water bottom adhesion type self-stabilization oil and gas transport pipe is good in stability, high in safety performance and remarkable in disaster reduction effect.

Description

technical field [0001] The invention relates to the technical field of pipeline production for the development and transportation of resources such as underwater oil and gas and combustible ice, in particular to a bottom-attached self-stabilizing oil and gas transportation pipeline. Background technique [0002] Submarine pipelines are an important part of the development and transportation of offshore oil and gas, combustible ice and other resources, and are the main means of oil and gas transportation. With the rapid development of marine economy, the use and development activities of sea areas are becoming more and more frequent, and the number of submarine oil and gas pipelines is increasing at an alarming rate. Submarine pipelines, especially deep-sea submarine pipelines, are usually laid bare or buried shallowly attached to the seabed. They are greatly affected by waves, currents, earthquakes, and submarine geological changes. Their stability is one of the key issues i...
