Abstract: Offshore oil and gas exploration and development are facing huge risks and challenges, especially the disposal of uncontrolled offshore blowout, which is extremely difficult. In order to study the emergency rescue technology during uncontrolled offshore blowout, this paper analyzes the limitations of rescue operations during offshore blowout through the investigation of cases about offshore blowout at home and abroad, and studies the mature well control emergency rescue process on land and offshore wells abroad based on the source control method. This paper analyzes the limitations of emergency rescue during blowout in shallow sea, and puts forward suggestions on the development direction of emergency rescue of shallow sea during blowout in the next stage in China.
