摘要: An automated system for detecting fluid influx into a wellbore during the transient conditions that occur after pumps stopped. The comprises at least one sensor normally employed on drilling rig measuring parameter, and processor receiving signal indicative of parameter from sensor. is programmed to analyze plurality values measured previous events so as generate predetermined threshold value, compare received provide an output when beyond value.
