Description
Technical field
The present invention relates to field produces technical field, particularly a kind of disinfecting inhibiter, be mainly used in oil gas water gathering line in field produces, inject the control of medium bacterium and the control of corrosion in water gathering line, water injection well, oil well pipe.
Technical background
In oilfield process, whole production system oil gas water gathering line, inject water gathering line, water injection well, in oil well pipe, medium is due to the reduction of temperature, a large amount of SRB bacteriums can be bred in medium, the reproductive process of SRB bacterium can produce a large amount of hydrogen sulfide, hydrogen sulfide increases the corrosion of medium on the one hand, simultaneously, the ferrous ion that the ferrous ion of hydrogen sulfide in medium or corrosion produce is combined generation iron sulfide precipitates, the generation of iron sulfide precipitates increases again the fouling of system conversely, cause underdeposit corrosion, and the lower bacterial reproduction aggravation of dirt, bacterial reproduction produces hydrogen sulfide, hydrogen sulfide increases again corrosion and accelerates bacterial reproduction, production system is caused to occur vicious cycle, the medium sent in pipe not only uniform corrosion aggravation, and underdeposit corrosion aggravation, corrosion failure frequently occurs, have a strong impact on normally carrying out of field produces, and the breeding of bacterium can not be controlled by adding inhibiter, after bacterial reproduction creates iron sulfide precipitates, in system metallic walls, the attached collection of foulant causes inhibiter can not in metallic surface film forming, corrosion mitigating effect significantly reduces, therefore, vegetative for sending medium to have in pipe in oil field development system, reduce except corrosion except adding inhibiter, sterilant must be added simultaneously and carry out sterilization, the only effect of competence exertion inhibiter effectively controlling vegetative while, the generation of reduction or Controlling System corrosion failure.So develop a kind of disinfecting corrosion inhibitor, can either reduce dielectric corrosion in metallic surface film forming again can the disadvantageous effect to inhibiter effect that effectively bacterial reproduction causes in control agent, the generation of the corrosion failure phenomenon of minimizing or Controlling System, improve oil field development system corrosion control effect, improve production timeliness, reduce production run cost, guarantee that the raising of field produces benefit has very important significance.
There is a large amount of inhibiter in the market, but owing to not possessing sterilization effect, therefore need to add sterilant in addition in the measure of Systematical control corrosion, such one side needs to increase medicine machine, also need the compatibleness experimental evaluation carrying out inhibiter and sterilant on the other hand, add unnecessary cost to drop into, therefore, exploitation disinfecting corrosion inhibitor, reduce corrosion control cost, improve the corrosion control effect of medium in pipe in oil field development system, expand the Application Areas of oil field corrosion control and bacterial control, need constantly to develop new product and new technology, to meet the requirement that field produces changes day by day.
