DOWNHOLE MATERIALS OPTIMIZATION FOR HARSHPETROLEUM PRODUCTION

摘要

This paper presents the outcome of a comprehensive program of work to establish thesuitability and performance of candidate inhibitor packages for downhole productionapplications. It covers both CO2 and H2S corrosion performance of carbon and low alloy steeltubulars in simulated field conditions. Inhibitor performance was established through using anumber of inhibitor selection methods by systematic determination of efficiency, persistencyand chemical compatibility of both conosion and combined corrosion/scale inhibitorpackages. The results have led to determination of effective means of corrosion mitigation toenable wider uses of carbon and low alloy steels for downhole applications.
