الكشف المبكر عن الاندفاع والتحكم بالبئر

في جملة واحدة

A kick is formation fluid entering the wellbore. Left unchecked it becomes a blowout. This watches eleven sensor streams and warns the crew minutes earlier than pit-volume alarms do.

المشكلة

Conventional detection waits for pit gain or flow-out excess to cross a fixed threshold. Both are late indicators, and on a floating rig or in a high-noise pit system they are late by a wide margin.

Every minute of delay increases the influx volume that has to be circulated out, and with it the casing pressure the crew has to hold.

كيف تعمل

A multivariate residual model learns the expected relationship between flow-in, flow-out, pit volume, standpipe pressure, hookload, block velocity, ROP, torque, and mud density during normal circulation. Deviation is scored as a joint anomaly rather than per-channel threshold crossing, which suppresses the false alarms that come from pump strokes, connections and rig heave.

Detection runs on the edge node at the rig, not in a data centre. The alarm path continues to work with the WAN link down, which is a requirement, not a feature.

البيانات المطلوبة

  • High-frequency (1 Hz or faster) flow-in and flow-out, ideally with a Coriolis or paddle-corrected flow-out measurement
  • Active pit volume, trip tank volume, pump stroke counters
  • Standpipe pressure, hookload, block position, rotary torque and RPM
  • Mud properties from the daily mud report: density, PV, YP
  • Labelled historical kicks — a minimum of fifteen real events, or a validated simulator set

ما الذي تحصل عليه

  • Graded alarm on the driller’s HMI and the company-man display, with the contributing channels named
  • Rolling influx-volume estimate and time-to-shut-in guidance
  • Post-well event report with the detection lead time versus the conventional alarm

ما لا تستطيع فعله

This reduces detection time; it does not replace the driller, the well-control procedure, or the flow check. It is deployed as an advisory alarm and is not certified to any functional-safety integrity level. In connections and during tripping the model is deliberately desensitised, so a kick taken while tripping is still detected primarily by the trip tank.
