الملخص

يهدف هذا البحث إلى التنبؤ بتأثير نفاذية الوسائط المسامية وتاثير الثقوب على انخفاض الضغط ومؤشر الإنتاجية ، لحفرة البئر العمودية المثقبة، تحتوي على ستة ثقوب ولزوايا طور مختلة. الزاوية الأولى 60 درجة مع التوزيع الحلزوني وزاوية الطور الثانية 180 درجة مع التوزيع الطبيعي. في هذه الدراسة، تم استخدام برنامج ديناميكيات الموائع الحسابية (CFD) لمحاكاة نموذج لتدفق السوائل المضطرب ثلاثي الأبعاد مع معيار k − ، والحالة المستقرة، وطور واحد. تمت دراسة تأثير نفاذية الوسائط المسامية ومعدل تدفق كتلة المدخل من الوسط المسامي ،وطول الثقوب، وقطر الثقوب لحالتين من زوايا الطور. أظهرت نتائج هذه الدراسة أن انخفاض الضغط يتناقص مع زيادة نفاذية الوسائط المسامية، وبالتالي يزداد مؤشر الإنتاجية. أيضا، زيادة معدل تدفق كتلة المدخل من الوسائط المسامية مما يؤدي إلى زيادة انخفاض الضغط. طول الثقوب له تأثيرات قليلة على انخفاض الضغط ومؤشر الإنتاجية، بينما يكون لقطر الثقوب تأثير أكبر على انخفاض الضغط.
