Three-dimensional multi-layer oil and gas pipeline safety detecting system

Abstract

The invention discloses a three-dimensional multi-layer oil and gas pipeline safety detecting system which is provided with a medium supply area, a simulated buried pipeline area and an overhead pipeline area. A pipeline medium supply device is installed in the medium supply area, and a lower layer simulated buried long-distance pipeline integrity detection simulation system is installed in a trench of the simulated buried pipeline area, and upper two layers of overhead pipeline simulation subsystems are installed in the overhead pipeline area. The three-dimensional multi-layer oil and gas pipeline safety detecting system has the advantages that corresponding scene simulation is performed against problems that may occur in oil and gas pipelines in different actual scenarios, and the simulation conditions are presented hierarchically; for the actual transportation environment of oil and gas pipelines, the pipeline environment exposed to the air is simulated by the overhead pipeline simulation subsystems respectively, the buried pipeline environment is simulated by the simulated buried long-distance pipeline integrity detection simulation system, and the two are tested in different regions; the simulation conditions and teaching effects are straightforward and simple, which helps students to visually observe and learn fault points and fault situations and is concise, efficient and attractive.

Description

technical field [0001] The invention relates to the technical field of oil and gas safety engineering, in particular to a three-dimensional multi-layer oil and gas pipeline safety detection system. Background technique [0002] Because oil and gas pipelines are affected by many reasons such as natural corrosion, aging, natural disasters, loose connections of pipelines and man-made damage, pipeline leakage accidents occur from time to time. If toxic, harmful, flammable and explosive substances are transported, it is easy to cause personnel poisoning, Serious accidents such as fire and explosion occurred. [0003] However, because pipelines usually travel a long distance and involve a wide range, when the pipeline leaks, is damaged, or the pipeline coating is damaged, it is difficult to find the fault point of the pipeline defect, and it is impossible to determine the severity of the defect fault. Technology is not ideal for the simulated detection of pipeline accidents. The...

Problems solved by technology

[0002] Because oil and gas pipelines are affected by many reasons such as natural corrosion, aging, natural disasters, loose connections of pipelines and man-made damage, pipeline leakage accidents occur from time to time. If toxic, harmful, flammable and explosive substances are transported, it is easy to cause personnel poisoning, Serious accidents such as fire and explosion

[0003] However, because pipelines usually travel a long distance and involve a wide range, when the pipeline leaks, is damaged, or the pipeline coating is damaged, it is difficult to find the fault point of the pipeline defect, and it is impossible to determine the severity of the defect fault. Technology is not ideal for the simulated detection of pipeline accidents

As a result, it takes a lot of work to find the fault points of pipeline defects, the cost of pipeline maintenance and repair is high, and the energy substances inside the pipeline cannot be transported normally, which affects normal work and wastes resources.

[0004] And because the pipeline involves a wide range and covers a large area, on-site pipeline simulation testing teaching needs to travel long distances to different locations for observation and learning. The teaching conditions are difficult, and the teaching quality is poor and the teaching cost is high. It is difficult to cultivate high-skilled professionals. inspector

[0005] However, the simulation device used in the prior art, such as an oil and gas pipeline defect detection and monitoring experimental platform disclosed in the patent No. CN201610407890.7, has a complex structure and chaotic layers, and the structure of each layer is a structure of inner and outer rings. , the corresponding simulation is not carried out for different actual situations, and the effect of real simulation cannot be achieved, so the teaching effect is not ideal
