Corrosion Resistance of E-Glass Fiber in Simulated Oilfield Environment
Abstract:
Corrosion behavior and mechanism of E-glass fiber in simulated oilfield environment including CO2, H2S and Cl- were firstly studied. After simulated corrosion test, morphology of E-glass fiber was gathered using SEM. Chemical bonding status and elemental analysis were systematically investigated by XPS, FT-IR and EDS. The results revealed that corrosion of E-glass fiber in simulated oilfield acidic medium was primarily attributed to ion exchange mechanism, which was not only controlled by acid concentration, but also dominated by formation of complex ions or insoluble salts. The depletion of cations on E-glass fiber surface can disrupt the continuity of glass network, therefore reducing the strength of fiber.
