Description
Technical field
The invention belongs to neutralization technology fields, and in particular to a kind of compound acidification corrosion inhibitor.
Background technology
Acidification is a kind of measure of intensified oil reduction, is an effective technical measures of well production increment, water injection well stimulation.
Its principle is the dissolving and corrosion by acid solution to tamper in rock cement or formation pore, crack etc., restore or
Improve the permeability of formation pore and crack.During oil gas well mining, it is often necessary to improve recovery ratio by acidification.But
During acidizing treatment, acid solution can not only damage ground installation and underground pipeline to corrosion of metal, and corrode big
Amount iron ion can form iron oxide precipitation under certain condition, influence acidizing effect, be also possible to that downhole tubular goods is caused to happen suddenly sometimes
Property break accident, cause serious financial consequences, at this moment just need acidification corrosion inhibitor is added and solve these problems.
Acidification corrosion inhibitor be by debita spissitudo and in the form of be present in environment（Medium）In, it can prevent or slow down corrosion
A kind of mixture of chemical substance or several chemical substances.It can reduce corrosion of the acid to equipment, extension tube to the maximum extent
The service life on road ensures that acidizing treatment is smoothed out.The quality of acidification corrosion inhibiter is related to the success or failure of acidizing treatment.It is wide at present
The general corrosion inhibiter used, majority are organic amine, imidazoline, amide, thiocarbamide, heterocyclic ketone, quaternary ammonium salt etc., this type acidification corrosion inhibitor
But with the emergence of high temperature deep well, temperature improves the corrosion mitigating effect of corrosion inhibiter and is decreased obviously in acidization.Therefore, raw
A kind of efficient corrosion inhibiter of output is necessary.
Invention content
The technical problems to be solved by the invention：Oil field tubulars easily occur in the process for oil acidification is exploited in current oil field
