Intelligent conveying pipeline capable of displaying pipeline blockage position

Abstract

The invention discloses an intelligent conveying pipeline capable of displaying a pipeline blockage position. The intelligent conveying pipeline capable of displaying the pipeline blockage position comprises an inner-layer pipe, a steel wire reinforcing layer, a compression-resistant layer, an optical fiber ribbon layer and an outer-layer pipe which are sequentially arranged from inside to outside, wherein the steel wire reinforcing layer and the compression-resistant layer are both single-layer or multi-layer. According to the intelligent conveying pipeline capable of displaying the pipeline blockage position provided by the invention, the optical fiber ribbon co-extrusion mode is adopted, an optical fiber ribbon prepared in advance is ingeniously combined with a gathering and transportation pipeline, and the pipeline blockage position is judged according to the temperature change of the gathering and transportation pipeline. When blockage occurs, the blockage position can be quickly positioned, operation can be recovered only through fixed-point excavation and simple repair, and the intelligent conveying pipeline capable of displaying the pipeline blockage position is simple and efficient. In addition, the optical fiber is high in reliability, can work in a severe environment, is not influenced by temperature, humidity and pH value, is durable, does not need to shield an electromagnetic field during use, is high in use sensitivity, and is convenient to detect.

Description

technical field [0001] The invention belongs to the field of intelligent transportation pipelines, is specifically applied to the field of oil gathering and transportation, and relates to an intelligent transportation pipeline capable of displaying the position of pipeline blockage, which can judge the position of pipeline blockage by using optical fiber signal changes. Background technique [0002] Pipeline blockage during oil transportation has always been a common problem in the oil industry. Once the pipeline is blocked, it is the key to solve the problem to locate the location of the pipeline blockage in time. If it cannot be located in time, it will cause serious losses to the oil industry. The length of oilfield gathering and transportation pipelines is often tens of kilometers, or even tens of kilometers. During operation, if a blockage occurs in the past, there is no way to determine the location of the blockage. It can only be dredged forcibly by means of pressuri...

Problems solved by technology

Once the pipeline is blocked, it is the key to solve the problem to locate the location of the pipeline blockage in time. If it cannot be located in time, it will cause serious losses to the oil industry.

Oilfield gathering and transportation pipelines are often tens of kilometers or even tens of kilometers in length. In the course of operation, if a blockage occurs in the past, there is no way to determine the location of the blockage.

It can only be dredged forcibly by pressurization, which will easily cause the pipeline to burst, resulting in waste of oil resources and the risk of polluting the environment
