Abstract

The invention discloses a marine oil-gas horizontal pipeline support and hanger mounting interval optimization method, which comprises the following steps that firstly, the basic parameters of a horizontal pipeline are obtained according to the early-stage design, including the pipeline length, the pipeline diameter and the like; the maximum value of the distance between every two adjacent supports and hangers is determined according to the requirement of primary stress and serves as an initial value, and iterative optimization is conducted by reducing the distance in MATLAB software; and finally, modeling and simulation analysis are performed on the pipeline and the support hanger to obtain a horizontal pipeline support hanger mounting model which meets both the design requirement and the actual limit stress requirement. By the adoption of the method, rapidity and accuracy of pipeline support and hanger design can be guaranteed, meanwhile, the strength requirement of the support and hanger during installation and use is met, and engineering cost is effectively reduced.

Description

technical field [0001] The invention relates to a pipeline installation method, in particular to a method for optimizing the installation distance of support and hangers of offshore oil and gas horizontal pipelines. Background technique [0002] The pipeline installation needs to ensure the safety and reliability of the pipeline system. When designing the pipeline installation, in addition to ensuring that the pipeline layout meets the requirements and the arrangement is reasonable, the support and hanger should also be set up reasonably. The calculation of the distance between the pipeline supports and hangers is an important link in the design of the pipeline. Only when the distance between the supports and hangers is reasonably selected under the premise of meeting the standards and ensuring safety and reliability, can the goal of high quality and low cost be achieved. [0003] At present, the design of pipeline supports and hangers in China is mainly based on the formula...
