Gulf of Mexico Oil Spill Gulf of Mexico Oil Spill On April 20, 2010, a semi-submersible drilling platform leased by BP in the U.S. Gulf of Mexico* * Fire. 36 hours later, the platform sank, killing 11 staff members. The oil well at the bottom of the drilling platform has been leaking oil since the 24th, causing large-scale crude oil pollution. After the accident, BP stated that it was responsible for the crude oil spill. The oil spill in the Gulf of Mexico has become the worst ecological disaster in U.S. history. Affected by the oil spill in the Gulf of Mexico, the United States announced on May 25 that it would expand the local fishing ban area by 20,000 square kilometers. Because leaking oil wells have not been plugged for a long time, Obama * * It is also facing increasing external pressure, and its ability to govern has been questioned. Causes of the Gulf of Mexico oil spill: Baker said BP had only covered part of the drilling casing with cement, and the cement did not penetrate deep into the bottom of the second largest casing, an area where pressure is so great that upwelling of oil and gas is possible. The Los Angeles Times quoted some experts as saying that natural gas jumped up to the drilling platform through gaps, blowout preventers and oil pipelines, causing * * . In this oil spill, another oil well component that was criticized was the blowout preventer valve. it was supposed to be in the oil well * * After closing the oil well pipeline to prevent oil leakage, but it failed to do so ； It was supposed to respond to the deep-water robot's remote "call", but it still didn't. The Los Angeles Times reported that the blowout preventer had seven valves. One of the valves is used to cut off the oil pipeline in an emergency to prevent oil and gas leakage. some bp * Officials previously said that there are many possible reasons for the failure of the blowout preventer valve. They believe that the huge pressure when oil and gas erupts from the oil well presses casing fragments, wellhead accessories, and oil pipeline fragments into the blowout preventer valve, causing the blowout preventer valve to become stuck and unable to work. Otherwise, the deepwater robot should be able to remotely start it. However, the Washington Post reported on the 23rd, citing a letter, that in order to save time and money, a test valve was used in the Deepwater Horizon blowout preventer instead of a permanent "reducing gate", thereby increasing the risk of valve failure. According to the "Washington Post", the variable-diameter gate can close the oil pipe outlets of various sizes. The letter was written on October 11, 2004 by Christopher Young, senior marketing operations officer of Swiss Transocean Drilling. The test valve will be used by Swiss company Transocean Drilling, the letter said. On October 19 of the same year, BP signed a letter agreeing to the Swiss Transocean Drilling Company's plan. At this stage, the investigation into the cause of the blowout preventer failure is still continuing. “Deepwater Horizon” on the 20th of last month * * , soon sank into the Gulf of Mexico, and oil wells at the bottom began to leak oil. So far, no breakthrough has been made in plugging leaks. USA * * Said that the oil well leakage is currently 5,000 barrels per day. But some experts estimate the spill could reach 70,000 barrels per day. The above is part of the content, see for details http://baike.baidu.com/view/3609479.htm?fr=ala0_1 The following is discussed by myself. You can chat about anything. You are willing to talk about technology, environment, and personal opinions. There is no need for detailed demonstration process or objective evidence. Let's talk about whatever you want to say.
I personally feel that this is a big trouble, and it is estimated that it will affect the local area for more than ten years, and even affect the whole world. At such a deep location and under such working conditions, it is completely impossible to seal the leaks because the pressure is too great. We can only wait for new technologies or pressure leaks to decrease in the future (Monkey year and Horse month). Drilling pressure relief wells and other measures are just temporary treatments. With so much crude oil leaking every day, and the upcoming hurricane season, even some of the current temporary treatment tasks will not be possible. It can be said that there is no escape from the fact that the Caribbean Sea is completely polluted. If this area is polluted, the ecological environment of the seabed will be devastated, and it will be impossible for coral reefs and the like to return to their original state within hundreds of years. For the creatures in this area, it is no less than a nuclear pollution. This is still preliminary. The following is just nonsense. The specific gravity and heat absorption capacity of crude oil are very different from that of seawater. If it is polluted, it will affect the temperature and density currents in the ocean. And through the influence of ocean currents, it affects the global climate. Personally I don't think it's alarmist. Don’t forget the El Niño current, which looks much smaller on the map than the entire Caribbean Sea. Anyway, I think this time could be the beginning of 2012?
When foreigners see our environmental pollution and talk nonsense about it, they must be polluting themselves this time, so they must be outraged. It is useless to discuss anything else. Blocking the oil well is the last word.
It is said that the use of pressure relief wells is the fundamental solution. Technically I don’t understand it, but literally it feels like “combination of removing blockage”. Last week, we saw in the news that a large-scale deep-sea oil platform will be launched into the sea in the near future, emphasizing the corrosion resistance of steel structures and the complexity and redundancy of pipelines and systems. Large oil platforms are really complex. . . .
Personally, I feel that the pressure relief well is just a temporary solution. For an oil field to be valuable for extraction, it must have large reserves. What is the pressure under the deep sea crust? 10 meters of sea water is one atmosphere. Not counting rock pressure. What effect does drilling a pressure relief well have? . . After all, the pressure relief well does not directly release the pressure according to the seabed pressure, but still needs to control the outlet pressure, otherwise it will be an uncontrollable spray point. This is not land yet, so we can't spray it casually.
If there is a group of "railway guerrillas" each carrying two oil barrels over. . .
Watching TV today, it was said that more than 13,000 tons are leaked every day. No wonder the United States is ruthless against the United Kingdom. I changed it to something else.* * , you will have to go bankrupt...I am not an oil producer. But a small negligence of everyone in our petrochemical industry may cause a big disaster. I am still worried about our PetroChina. Everyone should do their jobs and don't let tragedies happen to us.
What about those people in China who are fishing for gutter oil? Come on~~~~~~
Reply 8# dongliangsir Yes, speaking of the foreigners I have worked with, it is not that no one in China can fulfill their requirements, but no one wants to do it at all. It would be tragic if something similar happened in the South China Sea.
I have a deep understanding of the quality of the platforms manufactured in China in recent years. I am really worried about what will happen to our platforms after they are launched into the water.
