First, let everyone know a little bit about drilling. Generally speaking, to produce oil, after the oil reservoir is discovered somewhere, the oil company starts to determine the first eye in a fixed place, and this eye extends all the way to the place where there is oil. where the whole process is called drilling. Drilling platforms on land are generally towed by trucks, while drilling platforms on the sea are towed by large ships. After drilling and completion of the well, the "eye" should be fixed with cement or steel casing, and then perforated at a specific part of the casing, and then the oil in the reservoir should be connected with the tubing, which is the later oil recovery. Before oil production starts, all drilling equipment will be withdrawn. To ensure that oil is continuously produced from oil wells, it is necessary to have sufficient understanding of formation conditions, and the most important thing is to monitor oil well pressure. We know that the formation pressure exists, and the reservoir pressure also exists. When drilling through the oil layer, the oil coming out is the proof of the pressure. This phenomenon is called well kick or blowout. In the process of drilling, a liquid with a larger specific gravity is generally used to prevent blowout, P= ρgh> formation pressure, ρ is the specific gravity of the drilling fluid, and h is the height of the liquid column.
Now, let's talk about the accident in "Deep Sea Catastrophe". BP hired Transocean to drill a well in the Gulf of Mexico. The project has been delayed due to the complicated formation conditions. The owner, BP, is urging the completion of the well as soon as possible in consideration of the company's interests. Oil production, but Transocean has been proceeding cautiously from the perspective of safety, and invited Schlumberger to do further testing. Unfortunately, the testing personnel were fired by the owner BP, and unfortunately the main person in charge of Transocean did not know The deep-sea oil well was ready for production under extreme conditions. When a large amount of drilling fluid was pumped out, the pressure balance of the oil layer was destroyed, and the oil rushed to the drilling platform and exploded.
One of the biggest gains from the development of industrial civilization to this day is the awareness of safety. A large number of safety production accidents have allowed people to summarize rich experience and lessons, so that more people have not become careless and lucky ignorant ghosts. People who are engaged in production may have such an experience, luck has always been the worst enemy of safety, because it is difficult for people to learn from past accidents because of luck: it will not happen at this time, it will not happen at this time. It doesn't happen to me in this place. Safety is a heavy topic, no amount of confirmation in advance, and no regrets after a disaster.
Another inspiration given to me by the accident is the emergency response of the characters in the play after the explosion. The scene of the blowout and explosion is no less than a war scene. The fire is serious and the damage to the equipment is so huge. Experience led everyone to leave the accident scene and successfully closed the valve to prevent further accidents (although we know that in the actual Gulf of Mexico accident, it was not successful). The ending of 7 people being seriously injured and 11 people missing should be the smallest loss in the accident. All those who contributed to this accident are the heroes of this accident.
