Not only the on-site flowing state of the oil-gas pipeline is reduced, but also the corrosion conditions of different positions and different directions of the pipe wall can be tested, and an electrochemical test and a corrosion weight loss test can be simultaneously carried out, so that the on-site corrosion condition of the oil-gas pipeline can be effectively predicted.
Description
Technical Field

Background
More and more acid gas fields enter the development line worldwide, H 2 S、CO 2 And serious pipeline corrosion is caused by various corrosive media, so that a plurality of safety accidents are caused, and the normal production order of the oil and gas field is seriously influenced. Therefore, a series of corrosion monitoring and detecting technologies, corrosion control technologies and the like are generated and applied to corrosion prevention of oil and gas fields, and play an important role. The corrosion monitoring is carried out on the pipeline, the potential failure risk is found in time, the economic loss and the environmental pollution caused by the pipeline leakage are avoided, and the method has important significance.
At present, hanging piece monitoring and probe monitoring are the most widely applied monitoring methods in oil and gas fields. The corrosion coupon method is the most traditional corrosion monitoring means, namely, the corrosion coupon is inserted into a medium and taken out after a period of time, and the corrosion degree is evaluated by measuring the change of the mass of a test piece and accumulating the change of the mass of a material caused by corrosion in unit time. The technical knowledge required by the probe for monitoring is simple, the monitoring period is short, the result analysis difficulty is general, and the probe is mainly used for measuring the uniform corrosion rate of metal.
In order to reasonably predict the corrosion condition of the natural gas pipeline, the flow conditions of the site, including gas concentration, liquid temperature and the like, need to be reduced. However, most of the existing oil and gas pipeline corrosion test is carried out in a reaction kettle, the flowing state of the pipeline cannot be really reduced, the method is far away from the flowing working condition of the pipeline on site, and the corrosion conditions of different positions and different directions of the pipeline wall cannot be further researched, so that the test result of the reaction kettle and the corrosion conditions on site have larger errors, and the pipeline is difficult to be accurately predicted in a corrosion mode.
