FTP، اختصار لـ ضغط أنبوب التدفق، هو قياس أساسي في إنتاج النفط والغاز، يوضح الضغط داخل سلسلة الأنابيب عند رأس البئر عندما يكون النفط أو الغاز في حالة التدفق. وهو معلمة رئيسية لفهم أداء البئر وتحسين الإنتاج.

Scenario: An oil well has been producing for several years. The FTP has been steadily declining over the past few months. The operator suspects the decline is due to a combination of factors:
Task:
**1. Key Factors Affecting FTP:** * **Reservoir pressure:** Depletion leads to lower driving force for fluid flow, decreasing FTP. * **Tubing condition:** Wear and tear, including corrosion, can cause increased pressure drop, lowering FTP. * **Flow rate:** The decline in FTP might be contributing to a lower flow rate. **2. Possible Actions:** * **Artificial Lift:** Installing a pump in the well to assist fluid flow, compensating for declining reservoir pressure. * **Tubing Replacement:** Replacing the existing tubing string with new, undamaged tubing, removing restrictions and improving flow efficiency. **3. Explanation:** * **Artificial Lift:** A pump can provide additional pressure to push fluids to the surface, overcoming the decreased reservoir pressure and increasing FTP. * **Tubing Replacement:** Replacing the tubing string with new, clean tubing eliminates internal restrictions and improves flow, leading to a higher FTP and increased production.
