Safety determination method and device for pipeline cleaning process and computer storage medium

Abstract

The embodiment of the invention discloses a safety determination method and device for a pipeline cleaning process and a computer storage medium, and belongs to the technical field of oil gas. The method comprises the following steps: acquiring basic data of a target pipeline, wherein the target pipeline is any pipeline in to-be-evaluated pipelines; according to the basic data, a pigging impact model of the target pipeline is established through a finite element method, and the pigging impact model is used for simulating stress conditions of a bottom elbow part of the target pipeline when the target pipeline is subjected to pigging operation under different conditions; simulating the stress condition of the target pipeline during pipe cleaning operation through the pipe cleaning impact model to obtain simulation data; and determining the safety of the target pipeline during pipe cleaning operation according to the simulation data. According to the embodiment of the invention, the stress condition of the elbow part at the bottom of the target pipeline is simulated, so that the safety of the target pipeline during pipe cleaning operation can be evaluated, the safety of the target pipeline during pipe cleaning operation is ensured, and the accident occurrence possibility is reduced.

Description

technical field [0001] The embodiments of the present application relate to the technical field of oil and gas, and in particular, to a method, a device, and a computer storage medium for determining the safety of a pipeline pigging process. Background technique [0002] With the development of society, the laying range of natural gas constant pipelines has become wider and wider. Among them, some long-distance pipelines will inevitably pass through places with many mountains, and pipelines are built according to the terrain, thus forming many pipelines with large drop. These large drop pipelines will face higher risks during pigging operations. For example, the pig will accelerate its movement under the action of gravity and pressure difference. When it reaches the bottom of the pipeline, the change of the movement direction will form a bottom elbow. Violent impact will cause the deformation of the pipeline structure, cause serious accidents such as collapse, and threaten t...
