    Description / Table of Contents: Corrosion problems in the Belayim oil fields. I. Influence of differnet variables on the corrosion rate in the flooding systemLaboratory and field tests were carried out in order to determien the corrosivity of the water used for flooding the Belayim oil fields. The influence of oxygen content, flow velocity, operating and standstill periods on the corrosion rate was investigated. The corrosion rate is lowest when all these variables and kept at their lowest possible values (flow velocity 0.5 metres pr. second; oxygen content 0.5 p.p.m.; operating time 30 per cent. of total time)-but this is uneconomical. The highest corrosion rate is encountered with high oxygen concentration (from 5 p.p. m. onwards) and with high operating time percentage.
    Notes: Zur Ermittlung der Aggressivität des im Ölfeld von Belayim benutzten Flutungswassers wurden Labor- und Feldversuche durchgeführt. Dabei wurden der Einfluß von Sauerstoffgehalt, Strömungsgeschwindigkeit sowie Betriebs- und Stillstandszeiten auf die Korrosionsgeschwindigkeit untersucht. Die Korrosion ist am geringsten, wenn alle diese Variablen auf einem möglichst geringen Wert gehalten werden (Strömungsgeschwindigkeit 0,5 m-sec, Sauerstoffgehalt 0,5 ppm, Betriebszeit 30% der Gesamtzeit), was jedoch unwirtschaftlich ist. Stärkste Korrosion tritt auf bei hoher Sauerstoffkonzentration (ab 5 ppm) und hohem Anteil der Betriebszeit.
