چکیده

در مطالعه حاضر، برای نخستین بار مـدل سه بعدی زمین شناسی مـخـزن آسـمـاری/شهبازان (مدل ساختمانی، مدل پتروفیزیکی، مدل تخلخل و مدل اشباع آب) میدان نفتی بالارود بـا استفـاده از اطلاعات ژئوفیزیکی، پتروگرافی و ساختمانی تعداد 6 حلقه چاه این میدان توسط نـرم افـزار مدیریت سیستم مخزن RMS ایجـاد گردید. بررسی پتروگرافی روی چاه نمونه (چاه شماره 1) نشان می دهد که عمده سنگ شناسی مخزن آسماری/شهبازان در این میدان سنگ آهک، دولومیت و سنگ آهک دولومیتی است. از تلفیق داده های موجود مشخص شد که مخزن آسماری/شهبازان در میدان بالارود را می توان به 5 زون تقسیم کرد که زون شماره 2 به 3 زیرزون تقسیم بندی می شود. بررسی نقشه های استخراج شده از مدل ها نشان می دهد که بهترین زون مخزنی از نظر ویژگی های پتروفیزیکی در مخزن آسماری/شهبازان زون 1 است. با استفاده از مطالعه مقاطع عرضی و طولی تهیه شده توسط نرم افزار مدیریت سیستم تغییرات ضخامت زون ها و نحوه گسترش زون های مخزنی میدان مورد مطالعه تعیین شد. بررسی مدل پتروفیزیکی مخزن آسماری نشان می دهد که محدوده ی شرق و شمال شرق مخزن از پتانسیل هیدروکربوری بهتری در مقایسه با سایر نواحی مخزن برخوردار است و هر چه لایه ها به سمت شمال شرق میدان گسترش می یابند کیفیت مخزنی بهتری از خود نشان می دهند. در محاسبات حجمی، حجم در جای هیدروکربور درشرایط متعارفی 013/226/658 بشکه محاسبه گردیده است.که از این میزان، بیشترین حجم نفت به زون شماره 1 مخزن اختصاص دارد.
