Regularity Corrosion of Nature Gas System of M Oilfield in Middle East Area
For the sake of finding out the corrosion cause of the M oilfield which was located in middle east area nature gas system,launching out the corrosion appraisal of the nature gas which was mixed with the production water,First,By making use of the gas chromatography,came up with the idea of corrosion pattern of H2S and CO2,second,analyzing the ion of the production water by titration method,ascertained the element of the ion and the regular pattern of the corrosion.the ion of Cl-,HCO3-which are the main corrosion factor of the M oilfield.By making use of the software,predict the corrosion rate under different pressure and temperature.By decreasing the water cut of natural gas system,effectively decreased the corrasion rate of the natural gas system.
