في مجال النفط والغاز، يشير مصطلح "خلع القطع" إلى عملية **فك مفصل أنبوب أو مكون من مجموعة القاع (BHA)**. هذه العملية المهمة غالباً ما تكون ضرورية أثناء أنشطة الحفر وإكمال البئر المختلفة، بما في ذلك:
1. استرجاع المعدات:
2. استبدال المعدات:
3. حل مشكلات استكشاف الأخطاء وإصلاحها:
خلع القطع: العملية
يتضمن فك مفصل **تطبيق عزم الدوران** على الوصلة، مما يؤدي إلى فك المكونات المملوكة بشكل فعال. تستخدم العملية عادةً معدات متخصصة مثل:
اعتبارات السلامة:
فك المفاصل هو جانب أساسي من جوانب عمليات الحفر وإكمال البئر. يُعد فهم هذه العملية، والمعدات المصاحبة لها، وأهمية احتياطات السلامة أمرًا ضروريًا لعمليات ناجحة وفعالة في مجال النفط والغاز.
