Test device of axial directional displacement of pipeline considering tension action of steel catenary riser

Abstract

The invention discloses a test device of axial directional displacement of a pipeline considering the tension action of a steel catenary riser. The test device comprises a test groove, oil transportation equipment, an oil outlet pipeline, an oil return pipeline, an outlet collection device, an outlet collection device and a test oil transportation pipe. Innovatively, according to the device, hot oil can be circulated in the pipelines, at the same time, the tensile force is exerted on the pipelines, and the magnitude of the tensile force can be adjusted, so that the situation a submarine pipeline can cause the axial direction displacement under the tension action of the steel catenary riser. Therefore, the influence of different magnitudes of tensile force on the rule of axial movement of the submarine pipeline is researched. Moreover, the speed and temperature of oil entering into the submarine pipeline can be accurately controlled by the device, so that a corresponding temperature variation curve of the submarine pipeline is obtained. Therefore, the influence of different temperature variation conditions on the axial directional displacement of the submarine pipeline.

Description

Technical field [0001] The invention belongs to the field of offshore oil and gas transportation engineering, and in particular relates to a test device considering the axial directional displacement of a pipeline under the tension of a steel catenary standpipe. Background technique [0002] With the further development of my country's offshore oil and gas resources, offshore oil and gas transportation is also facing greater challenges. As the main means of oil and gas transportation, submarine oil pipelines can be as long as hundreds of kilometers, and due to water depth limitations, pipeline maintenance is difficult. Once an accident occurs, it will cause economic, environmental, and ecological losses and cause irreversible consequences. Therefore, in the design stage, the pipeline should be systematically studied to analyze potential safety hazards to ensure the smooth progress of production. The axial directional movement of pipelines is a new problem in deep-sea pipeline en...
