AI Technical Summary
Existing downhole temperature and pressure monitoring technologies cannot effectively distinguish the coupling interference between temperature and pressure signals, resulting in errors in the acquired raw data and affecting the judgment of the actual downhole conditions.
Temperature and pressure sensing signals are independently acquired using downhole fiber optic sensing equipment, and associated with time and coordinate markers. After calculating and obtaining the original information, spatiotemporal alignment and coupling anomaly identification are performed, and a coupling evaluation channel is constructed for data cleaning.
It improves the accuracy of downhole temperature and pressure monitoring, ensures data accuracy, provides reliable monitoring support, and guarantees the safe and efficient operation of oil and gas extraction.
