Description

Technical Field

[0001] The utility model relates to the technical field of oil and gas drilling, in particular to a diesel power station for emergency rescue in oil and gas drilling. Background Technique

[0002] In the process of oil and gas exploration and development, once the high-pressure gas-containing fluid at the bottom hole loses balance with the circulating mud, the high-pressure fluid will overflow to the wellhead, causing a well kick. If it is not controlled in time or there is an operation error, a blowout will occur, resulting in problems such as personnel and equipment accidents and environmental pollution. During blowout emergency rescue operations, it is necessary to install a blowout preventer on the wellhead to carry out well killing emergency rescue operations, and the emergency rescue equipment for oil and gas drilling is an important equipment in well killing emergency rescue operations.
