Deepwater drilling gas cut monitoring and early warning processing method

The invention discloses a deepwater drilling gas cut monitoring and early warning processing method, relates to the field of deepwater drilling, and solves the problems that a traditional monitoring method is complex in judgment rule and low in reliability, the early warning time window is too narrow, the data return quality and the real-time performance are greatly influenced by the distance and the communication environment, and false alarm and misjudgment are likely to occur. The deepwater drilling gas cut monitoring and early warning processing method comprises the steps of data acquisition, feature optimization, working condition identification, data preprocessing, label processing, model construction, offline training and online early warning. Starting from an early marine riser monitoring method based on an ultrasonic Doppler effect and a logging monitoring method based on artificial intelligence, a gas cut monitoring method combining early monitoring and logging monitoring is researched; a gas cut ear
