This oil well has just been built and has not yet been put into production. It belongs to BP. BP's internal investigation shows that the explosion of Deepwater Horizon drilling platform in the Gulf of Mexico was caused by methane bubbles. In addition, the last line of defense "blowout preventer" of oil spill has failed before. Workers set and tested a cement seal at the bottom of the well, then reduced the internal pressure of the drill pipe and tried to set another cement seal. At this time, the chemical reaction caused by setting the seal generates heat, which leads to the formation of methane bubbles, thus leading to the destruction of this seal.
The 20 10 global annual hot word survey released by the global language testing agency on June 5438+04 shows that "oil leakage" ranks first. Reflects the global impact of the oil spill in Mexico.
According to an expert survey on May 27th, the oil leakage from subsea oil wells increased from 5,000 barrels per day to 25,000 to 30,000 barrels, making it the worst oil pollution disaster in American history. The floating zone of crude oil is 200 kilometers long and 100 kilometers wide, and it is still spreading further, and the pollution discharge operation may last for several months. In order to help the United States eliminate the pollution caused by oil spill, more than 10 countries and international organizations lend a helping hand to the United States. Mexico said that it will cooperate closely with the United States to avoid further damage to the ecological environment in this area. A Norwegian oil company promised to provide degreasing agent and equipment, and sent personnel. Iran will provide the United States with the technology of drilling relief wells to prevent crude oil from continuing to leak. The State Council spokesman philip crowley thanked all countries for their assistance.
If the maximum oil leakage per day is 4 million gallons, then another 3 months of oil leakage is equivalent to about 378 million gallons, that is, about 6.5438+0.43 million cubic meters. This may become the most serious oil spill disaster in peacetime (global). British Petroleum Company (BP) failed to plug the oil well in the Gulf of Mexico by "top killing method". In New Orleans, Louisiana, hundreds of people braved the rain to protest against the government's ineffective interception of oil by oil companies.
20 10 On June 23rd, the oil spill accident in the Gulf of Mexico in the United States worsened again: the underwater device originally used to control the oil spill point was removed for maintenance due to failure. As of June 20 10, 1, the oil leaked into the Gulf of Mexico is between170,000 gallons, which can fill 25 to 40 Olympic standard swimming pools. Even more frightening, the leakage continues, and the daily oil leakage varies from 12000 barrels to 19000 barrels, far exceeding the previous estimate of 5000 barrels.
Affected by the oil spill, President Obama had to announce that the suspension period of 33 deep-water oil drilling projects would be extended to six months, and the oil drilling projects off the coast of Alaska would be suspended.
BP is under pressure from public criticism. According to media reports, since the lease of "Deep Well Horizon" at the beginning of the year, BP has invested a huge amount of money, with a start-up capital of 654.38 billion US dollars. BP said it had spent 930 million dollars to deal with the oil spill, including measures to control the oil spill and accident compensation. 20 10 on may 26th, the governor of Louisiana said that the coast of Louisiana over160km was polluted by oil spill, which exceeded the total length of the coastline of Mississippi and Alabama. The ecological environment along the Gulf Coast is suffering from "catastrophe". Experts pointed out that pollution may lead to the destruction of wetlands and beaches along the coast of the Gulf of Mexico 1000 miles, damage to fisheries and extinction of vulnerable species.
"This time period is particularly sensitive because many animals are preparing to lay eggs. In the Gulf of Mexico, bluefin tuna are breeding, and their eggs and young fish are floating on the sea. Seabirds are nesting. For turtles that lay eggs, the beach is destroyed and its impact is fatal. " Larry crowder, a marine biologist at Duke University, said that a major oil spill would destroy the entire ecosystem and the economic activities based on it.
Weisberg, an oceanographer at the University of South Florida, is more worried that oil will be involved in the Gulf Stream. Because once it enters the jacket flow, it only takes about a week for the oil to spread to straits of florida; In another week, Miami beach will be polluted by oil. The crude oil entering the loop will pollute Turtle National Park and kill the local coral reefs, and then dolphins, sharks, wading birds and crocodiles in Everglades National Park will suffer. Because the leaking oil well has not been blocked for a long time, the Obama administration is facing increasing external pressure and its ruling ability is questioned. According to the latest data from CNN polling company, 5 1% of Americans are dissatisfied with Obama's handling of the oil spill, and 60% of respondents believe that the government has no ability to avoid similar incidents in the future.
Admiral Allen, commander of the US Coast Guard, said that the United States has not considered an alternative solution to the oil spill for the time being, and BP should continue its efforts to prevent the oil spill. During Bush's administration, he was criticized for his poor response to Hurricane Katrina. Now, the * * * Party has also seized Obama's "pigtail" and launched a fierce criticism. "After the oil spill in the Gulf of Mexico, President Obama has remained indifferent or alienated from both sides. For 35 days, he didn't use the effective resources of the government to solve this problem, "said Congressman Dalera Elsa from California.
* * * and the parties also ridiculed through the media. "In the course of the disaster, we saw that the president still had time to play golf, raise money for politics and hold state banquets." President Obama responded: "The oil spill in the Gulf of Mexico is worrying. On the day I got the oil well explosion report, I told the working team around me that we should seize the time and use all resources to effectively deal with the oil spill. " Obama also said that the government has sent 65,438+0,000 federal workers into disaster relief, and the government is taking all measures to control the spread of the disaster. However, Obama also reviewed the government's behavior.
