Evaluation of the efficiency of corrosion inhibitors for pipe steels in hydrogen-sulfide-containing media

Of the corrosion inhibitors currently used of greatest interest are imidazoline derivatives due to their high efficiency and processability. It is shown that the composition based on nitrogen containing organic compounds such as alkylimidazolines, isotrate, nonionic surfactants and solvent exhibits a high inhibiting properties in the reservoir water containing hydrogen sulfide and carbon dioxide. However, mineralized reservoir water with a low content of hydrogen sulfide or in its entire absence possesses a high degree of aggressiveness. The studies have shown that the compound obtained is ineffective as a corrosion inhibitor in this environment.

Hydrogen Sulfide Corrosion

Abstract A new method is proposed as a standard screening test for possible hydrogen sulfide corrosion inhibitors. This is a dynamic, weight-loss method which attempts to control conditions sufficiently well that substances which offer promise of being effective inhibitors under field conditions can be selected for further study. The test is cheap and simple, so that it can be run economically by a relatively untrained technician on large numbers of materials. The method is described and the reasons for choosing the particular conditions are explained. Then illustrations of the application of the procedure to a number of types of inhibiting substances are presented. 2.3.4

Sulfide Corrosion

Natural gas of Tazhong-1 gas field contains 7.7% carbon dioxide and 2.31% hydrogen sulfide, and produced water salinity is up to 140000mg/L,the well-bore tube has seriously potential corrosion destructive with natural gas being exploited. Based on the corrosion type partition of down-hole tube for eighteen production wells of Tazhong-1 gas field, P110,P110S and P110SS corrosion behavior were investigated under the conditions of simulated formation water containing carbon dioxide or hydrogen sulfide/carbon dioxide, and corrosion inhibitors were chosen to meet need of anticorrosion of Tazhong-1 gas field. The results show that fifteen wells in eighteen production wells belong to hydrogen sulfide corrosion of both hydrogen sulfide and carbon dioxide influence. Other wells are singular carbon dioxide corrosion. The most severe corrosion of three types of down-hole tubes all occurs at 90°C in both corrosion media, and their corrosion resistance order is respectively P110>P110S>P110SS and P110S>P110SS>P110 under the conditions of simulated formation water containing carbon dioxide or hydrogen sulfide and carbon dioxide. The selected anti-temperature corrosion inhibitors (YU-1、YU-4) can control the corrosion rate of three types of down-hole tubular goods within 0.076mm/a in simulated formation water media with carbon dioxide (PCO2=0.08～4.64MPa) or hydrogen sulfide and carbon dioxide (PH2S/Pco2=1.3/4.64Mpa) while added amount of the inhibitor is 120～300mg/L or 200mg/L. All of these provide technical support for safe and fast development of Tazhong-1 gas field.
