Abstract

The invention discloses an electrolytic bacterial corrosion prevention system, which comprises a power generation device, which is used for introducing natural gas extracted from an underground reservoir body and generating power by using the output pressure energy of the natural gas; the separation device is connected with the power generation device and is used for obtaining the natural gas passing through the power generation device and separating the natural gas so as to obtain produced water; and the oxidizing agent generating device is connected with the power generating device and the separating device and is used for producing a strong oxidizing agent from the produced water by utilizing the electric energy provided by the power generating device so as to sterilize the produced water by utilizing the strong oxidizing agent. The bacterial corrosion risk of the oil and gas field ground gathering and transportation system is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of petroleum and natural gas exploitation, in particular to an electrolytic anti-bacterial corrosion system and method. Background technique [0002] At present, bacterial corrosion widely exists in the surface gathering and transportation system of oil and gas fields. The existing oil and gas field ground gathering and transportation system often adopts a bacterial antiseptic solution that injects fungicides into the treated water. Bactericides are chemical synthetic agents, injecting them into the treated water will change the water quality of the treated water. In this way, it will not only increase the treatment cost of back-end water, but also cause certain pollution to the environment. [0003] In addition, due to the large amount of treated water produced in the oil and gas field surface gathering and transportation system, it is necessary to inject a large amount of fungicides into it to achieve ef...
