Emergency materials for workover operations in oil fields include positive pressure air respirator and air respirator inflators, eye washers, oxygen cylinders, oxygen bags, first aid kits, stretchers, explosion-proof flashlights, explosion-proof searchlights, emergency generators, satellite phones and explosion-proof walkie-talkies. The escape equipment for oil and gas field drilling and workover is an emergency and dangerous situation such as blowout, fire or strong wind, which cannot escape by vertical ladder.

Principle of workover blowout accident in oilfield

With the progress of science and technology in the new period, it has provided great convenience for industrial and agricultural production and development, and also provided great convenience for the oil exploitation industry. With the application of many technologies, the process of oil exploitation has become more and more simple.

However, this does not mean that the risk of the oil exploration industry will be reduced. Blowout accident, as an easy accident in the process of oil exploitation, should be paid attention to by oilfield operators.

The principle of oil well blowout is that with the increase of oil production, the crude oil at the bottom of the well is decreasing, the pressure on the formation is increasing, and the killing fluid overflows with the increase of pressure. If oilfield operators do not pay attention to this situation, it will lead to blowout events.
