Test system for monitoring pipe leakage and early warning safety

Abstract

The invention provides a conduit leakage inspection and safety early warning test system for oil-gas transportation conduit leakage inspection and corresponding early warning technique tests, relating to mechanical vibration or sound wave impact metering and conduit system technique field, comprising a circular conduit (53) which is connecting with a storage can region (2) and a pump (9) to be a close ring, is imbedded underground, is antiseptically treated and is cathodic protected, and a circular optical fibre (54) imbedded in one ditch. The circular conduit (53) has two lead-out branch pipes and a plurality of relief valve wells. A plurality of valves, volume meters and pressure instruments are provided on the conduit. An air compressor (26) is provided on one lead-out branch pipe, and another lead-out branch pipe is unloaded. A plurality of valves, pressure instruments and gas flowmeters are provided on the circular conduit. Pressure sensors of a circular conduit on-site instruments and remote transmitting cables transmit pressure signals to a central control room.

Description

technical field [0001] The invention is a pipeline leakage monitoring and safety early warning testing system for pipelines, especially oil and gas pipeline leakage detection and related early warning technology tests. It relates to the measurement of mechanical vibration or sound wave, the measurement of impact and the technical field of pipeline system. Background technique [0002] As the lifeline of the industrial economy, oil and gas pipelines occupy an important position in the national economy. Due to the defects of the pipeline itself, corrosion, natural aging and third-party damage caused by external forces, the loss of oil and gas products, environmental pollution and personal injury have been caused. In view of this, the pipeline transportation industry often has to spend a lot of manpower, material resources, and financial resources on research, transformation, and construction. With the continuous development of the pipeline transportation industry, in order t...

Problems solved by technology

[0005] Although these technologies all claim to be able to solve the problems of leak detection and safety warning of oil and gas pipelines, most of these technologies are systems obtained through theoretical analysis in the laboratory. Objective factors greatly affect the application stability and reliability of various systems, and directly have an important impact on detection accuracy and practicability

As an important energy artery in the country, oil and gas pipelines cannot directly provide the destructive experimental environments such as real leaks and drilling required for various leak detection and safety warning system tests. Therefore, there is an urgent need for a test and evaluation of various pipeline leak detection and safety warnings. A common test platform for the practicality of the technology
