永久性井下监测可以为采油决策提供有价值的信息 ,而不需通过各项采油修理工作收集资料。由于在生产层段安放测量仪表比较复杂 ,防砂完井一般不采用此类工艺。但是 ,在裸眼水平砾石充填式完井中采用光导纤维分布式温度传感器 ,就可以进行实时油藏监测。该砾石充填式完井分为 2 Permanent downhole monitoring can provide valuable information for oil production decisions without the need to collect data through various oil recovery work. Due to the complexity of measuring instruments placed in the production section, sand control and completion generally do not use such technology. However, the use of fiber optic distributed temperature sensors in open-hole, gravel-packed completions enables real-time reservoir monitoring. The gravel pack completion is divided into two
