%X With the development and exploration of oil-gas field, more and more oil-gas wells suffered from HES corrosion, which has serious effect on production and hereby restricts the development of oil field. Study on behavior of HES corrosion under dynamic conditionis is of significance. Corrosion tests were carried out in laboratory to simulate the tube corrosion rules under production conditions. Results showed that rate of dynamic corrosion increased with the increasing well depth in solutions with the same concentration of corrosive specieses by simulation tests, but pitting corrosion occurred at high temperatures. The corrosion characteristics is different from location to lcoation along the well depth. Support Vector Machine method may be applied to predict corrosion rates being in good agreement with the experimental results, thus provided a new method for predicting corrosion rate.
