Abstract:

In order to investigate the corrosion behavior of the sand screen material in stratum water, the corrosion of sand screen made of carbon/Alloy steels J55 is researched by changing the match of the Cl-, Ca2+ and the HCO3- in the stratum water saturated with CO2 to obtain the corrosion rate and slot width increment curve. Electron Microscopy is also used to acquire the corrosion morphology of the sample. The rule of the point corrosion and uniform corrosion is analyzed by combining the corrosion rate curve and corrosion morphology. The results show that the corrosion scale can be approximately divided into three layers. The outer layer is loose while the inner layer is compact. The corrosion rate and the slot width increment increase with the increasing of the ClG concentrations. However, the corrosion rate and slot width increment decrease with the increasing of the Ca2+ concentrations. The complexity of the HCO3- hydration results in the corrosion complexity. When the ClG concentrations are kept in a low level, serious pitting corrosion exists at most region of the sample surface. When the Cl- concentrations rise to a high level, the surface appears uniform corrosion. The existences of the Ca2+ help the sample resist from the further corrosion.
