الخلاصة


يتناول هذا البحث دراسة تجريبية لعملية التصريف بالجاذبية الحرة (FFGD) باستخدام نموذج Hele-Shaw ثنائي الأبعاد لتقييم تأثير قوة الدفع المائي على كفاءة استخلاص النفط في المكامن ذات الدفع المائي. تم إجراء تجارب على وسط رملي مائي البلل باستخدام طور هايدروكاربون غير منتشر (n-Decane) عند درجتي قوة دفع مائي مختلفتين. أظهرت النتائج أن قوة الدفع المائي العالية تؤدي إلى استخلاص سريع للنفط ولكن مع انتاج مبكر للماء، في حين أن القوة المنخفضة تطيل فترة الإنتاج وتقلل من انتاج الماء. كما تم إجراء مقارنة مع دراسات سابقة في وسط مسامي غير متجانس، حيث أظهرت النتائج أن عدم التجانس يُقيّد كفاءة تصريف الجاذبية، مما يؤدي إلى انخفاض معدل الاستخلاص النهائي للنفط مقارنةً بما لوحظ في الوسط المسامي المتجانس.


 تقدم هذه الدراسة أساساً تجريبياً لفهم أداء GAGD تحت ظروف دفع مائي، واقتراح الاستفادة من حقن الغاز للحد من انتاج الماء وتحسين الكفاءة.
