چکیده مقاله :
تولید بهینه از چاه‌ها و مخازن یکی از دغدغه‌های اصلی مهندسان مخزن و بهره‌برداری در صنعت نفت به شمار می‌رود. در برخی از مخازن، تغییر در خواص سیالات مخزن و همچنین تغییرات در پارامترهای عملیاتی، ضرورت بهینه‌سازی تولید را برجسته می‌سازد. بنابراین، بهره‌گیری از روش‌های بهینه‌سازی تولید از مخازن، یکی از موضوعات کلیدی در مهندسی بهره‌برداری محسوب می‌شود. در این مطالعه، عملکرد چاه گاز میعانی با استفاده از نرم‌افزار PIPESIM تحلیل شده است. نمودارهای عملکرد چاه، از جمله IPR و TPR، برای بررسی روند تغییرات فشار و دبی تولید به کار گرفته شده اند. بررسی¬ها نشان می دهند که افزایش دبی تولیدی موجب افت فشار ته چاهی شده و می تواند جریان دو فازی را در چاه ایجاد کند. همچنین، تحلیل گره‌ای نشان می¬دهد که انتخاب مناسب پارامترهای عملیاتی می تواند بهره وری چاه را افزایش دهد.
Optimal production from wells and reservoirs is one of the main concerns of reservoir and production engineers in the petroleum industry. In some reservoirs, changes in reservoir fluid properties as well as changes in operating parameters highlight the need for production optimization. Therefore, the use of reservoir production optimization methods is one of the key issues in production engineering. In this study, the performance of a condensate well is analyzed using PIPESIM software. Well performance graphs, including IPR and TPR, are used to examine the trend of pressure and production flow changes. Studies show that increasing production flow causes a drop in bottomhole pressure and can create two-phase flow in the well. Also, nodal analysis shows that the appropriate selection of operating parameters can increase well productivity.
