Corrosion inhibitor evaluation integrated device and using method thereof

Abstract

The invention discloses a corrosion inhibitor evaluation integrated device and a using method thereof. The corrosion inhibitor evaluation integrated device comprises a constant temperature magnetic stirring device, a bottle body device, an aeration device, a venting device, an outer cover inner cover and bracket device, and a dosing and temperature monitoring device; the bottle body is detachablyfixed to a heating panel of the constant temperature magnetic stirring device; the aeration device comprises an aeration port extending from the bottom of the bottle body into the bottle body, and a shut-off valve connected to an aeration port pipe; the venting device is disposed at the bottom of the bottle body; the inner cover inner cover and the bracket device further comprises an outer cover,an inner cover and a bracket; and the dosing and temperature monitoring device comprises a ceramic hollow column, a temperature sensor placed in the ceramic hollow column and the induction probe is inserted into the bottle solution, and a dosing hole. The invention has the advantages of simple structure, convenient operation and high degree of automation; therefore, the problems that the laboratory corrosion inhibitor evaluation is difficult and the parallel degree of the experimental data is poor are effectively solved, the time and space of the experiment evaluation are saved, and the detection level is improved.

Description

technical field [0001] The invention belongs to the technical field of instruments and devices, and in particular relates to an integrated device for evaluating corrosion inhibitors and a method for using the same. Background technique [0002] The use of metal equipment cannot be avoided in the process of oil and gas field exploitation, and the corrosion of metal equipment is one of the most concerned problems in oil field operations. Therefore, it is extremely necessary for oilfield production to choose a high-quality corrosion inhibitor to inhibit metal corrosion. The screening and evaluation of corrosion inhibitors in the laboratory has become an important prerequisite for doing a good job in corrosion protection. Using a good corrosion inhibitor is not only a technical problem, but also related to resource protection, material saving, environmental protection, and normal production. A series of major social and economic issues such as the personal safety of [0003] A...

Problems solved by technology

During the corrosion inhibitor evaluation process, it is necessary to detect the dissolved oxygen of the prepared solution, and then hang the corroded metal after meeting the normal range of dissolved oxygen; the experimental evaluation bottle mouth is not sealed enough, and contact with the outside air will interfere with the experiment; secondly, the temperature The control has very strict requirements. At present, the temperature control requirements of the laboratory are not too precise, only to meet the ambient temperature, and the temperature of the corrosive liquid has not been accurately measured. Due to the heat loss during the heat transfer process, the experimental data is not very parallel. Ideal; finally, the lack of aeration conditions caused the prepared solution to be affected by the oxygen in the liquid, and did not play a real role as a corrosion inhibitor. It could not clearly guide the technical requirements of the site engineering, and the corrosive parameters of the equipment were not comprehensive enough. Cause losses to production and affect economic and social benefits
