Corrosion inhibitor for acid stimulation systems |
摘要 |
An oil well being subjected to an acid stimulation may be treated with a corrosion inhibitor including an Ammonium Iodide Ion Source, a first carbonyl containing compound having a general formula:;
and a second carbonyl containing compound having the general formula:
;
wherein R1 is an alkyl or aromatic group, R2 is a hydrogen, alkyl or aromatic group, and R3 is a hydrogen or an alkyl group having from 1 to 6 carbons; and wherein the alkyl or aromatic groups of R1, R2, or R3 may further comprise a nitrogen, phosphorous, halogen or second oxygen moiety; and wherein the oil well being treated has zone being treated at a temperature of from about 90 to about 500° F. |

1. A method of acidizing an oil well comprising employing a corrosion inhibitor before, during or after an acid stimulation of the oil well, the corrosion inhibitor comprising: an Ammonium Iodide Ion Source; a first carbonyl containing compound selected from the group consisting of ethyl butyrate, cinnamaldehyde, benzaldehyde, and combinations thereof; and a second carbonyl containing compound selected from the group consisting of acetaldehyde, formaldehyde, and combinations thereof; and wherein the first carbonyl containing compound and the second carbonyl containing compounds are different. |
