Abstract: ان التاكل الداخلي في انابيب الصلب الكربوني الذي يحدث بوجود غاز ثاني اوكسيد الكربون يعتبر مشكلة جوهرية في صناعات النفط والغاز وهو يقترن دائما مع وجود الماء. ان احتمالية حدوث التاكل تزداد بصورة عامة مع تزايد نسبة الماء ومع زيادة مستوى الماء المنتج تزداد مع | Internal corrosion of carbon steel pipelines occurring in the presence of CO2 is a substantial problem in the oil and gas industries. It is always associated with the presence of free water. The likelihood of corrosion generally increases with the volume fraction of the water phase. As the produced water level increases, the corrosion rates of carbon steel increase very rapidly and causes damage of petroleum and gas pipelines. The present research work focuses on the investigating of the corrosion rate of carbon steel as flow line in crude oil production with CO2 content employing three Iraqi crude oil (Kirkuk crude oil, Halfaya crude oil, Rumalia crude oil) with different brine concentrations [1%NaCl, 2%NaCl, 3%NaCl]. Determining the corrosivity of Iraqi crude oil was studied for the first time. Experiments were performed in an autoclave test apparatus, crude oil - produced water mixtures, water cuts were (0, 10, 20, 30, 40, and 100%), and total volume of mixtures inside the autoclave was always kept at 100ml and temperature (20, 40, 60°C). For all experiments, CO2 partial pressure was maintained at (4 bar) and rotational speed (500 rpm).The corrosion rates were determined by the weight loss technique. The results revealed that the corrosion rates of carbon steel increased by increasing water cut and temperature, but decreases with increasing salt concentration for all types of crude oil. Results also indicated that different crude oil has significantly different effects on corrosion of carbon steel, with identical brine compositions. Therefore, Rumaila crude oil exhibits the highest corrosion rates and Kirkuk crude oil exhibits the lowest corrosion rates while Halfaya crude oil exhibits a moderate corrosion rates e.g. at 1% NaCl, 20% water cut, temperature 60°C, pressure 4bar, the corrosion rate of carbon steel in Rumaila crude oil is 0.9163mm/yr whereas it is 0.564 mm/yr and 0.705 mm/yr in Kirkuk crude oil and Halfaya crude oil respectively. The Corrosion Rate Break produced water level was determined from the experiments. These tests are employed to evaluate the requirements for corrosion inhibitor treatment. At 100% water cut (brine/CO2) the corrosion rates of carbon steel was the highest. The presence of crude oil decreases the corrosion rates e.g. at 1% NaCl,100% water cut(brine/CO2) the corrosion rate is 7.1197 mm/yr, whereas at 40% water cut/ Rumaila crude oil the corrosion rate is 1.4097 mm/yr.
