التنبؤ بانحشار الأنابيب

في جملة واحدة

Warns that the string is becoming hard to move, typically twenty to sixty minutes before it stops moving at all.

المشكلة

A stuck-pipe event costs between two and fifteen days and occasionally the hole section. The warning signs — creeping overpull, rising torque baseline, degrading hole cleaning — are visible in the data for a long time before the event.

Crews see the signs but have no quantitative trigger, so the decision to circulate and back-ream gets deferred until it is too late.

كيف تعمل

Torque and drag residuals against a calibrated friction-factor model are combined with pack-off signature detection on standpipe pressure and a hole-cleaning index derived from cuttings return and flow rate. A sequence model scores the last two hours of behaviour rather than the instantaneous state.

Alarms name the mechanism — differential sticking, pack-off, or key-seating — because the correct response differs for each.

البيانات المطلوبة

  • Hookload, torque, block position and velocity at 1 Hz
  • Standpipe pressure and flow rate
  • Survey data and the friction-factor calibration per section
  • Historical stuck and near-stuck events with root-cause labels

ما الذي تحصل عليه

  • Graded risk indicator with the dominant mechanism named
  • Recommended action: circulate, back-ream, reduce ECD, or work the pipe
  • Post-event contribution report for the NPT database

ما لا تستطيع فعله

Differential sticking against a permeable sand gives good lead time. Sudden pack-off from a mobile salt or an unstable rubble zone can develop in under five minutes, and in those cases the model provides little or no warning. It is honest about which mechanism it is seeing, so the crew knows how much of the lead time to trust.
