The hottest oil spill scene in Penglai oilfield is

The oil spill scene of Penglai oil field witnessed: it may spill oil again at any time

Xinhua news agency took the "China Marine Surveillance 15" ship to the oil spill accident scene of Penglai oil field on the 15th to interview and learned that at present, there is still a small amount of oil spill on platform C, the oil spill source of the two oil spill accident platforms has not been determined, and ConocoPhillips has not taken effective measures to thoroughly investigate the oil spill source and cut off the oil spill source proposed by the State Oceanic Administration of China

Xinhua News Agency arrived at luanjiakou port in Penglai City at 8:20 on the 15th and took the ship "China Marine Surveillance 15" to sail to Penglai oil field about 50 nautical miles northwest of the port. About four hours later, the ship "China Marine Surveillance 15" arrived at its destination

in a layer of mist, I saw the drilling platform of Penglai oil field, where the "will be favored by more and more businesses" for the investigation of the impact of the oil spill accident on marine ecology. The ship "guohaijian 17" was sailing around the oil field. A dozen staff members of the North sea monitoring center of the State Oceanic Administration dressed in orange took samples on the deck, and no obvious oil film was seen in the sea area around platforms B and C

it was seen at the scene that there was still a burning open fire above platform C, which had been required by the State Oceanic Administration to stop production on the 13th. According to law enforcement officials, ConocoPhillips provided information that the open fire currently burning on platform C was not the natural gas produced by the production process of the platform, but the natural gas burned by the dynamic system of the platform. In addition to adjusting the focal length, there has been no oil spill in the sea area near platform B recently; The law enforcement personnel inspected and monitored the C platform every hour and found that there were still 20 to 30 oil sprays per minute, and the total amount of oil spilled in 24 hours was about 1 liter

on the 13th, the State Oceanic Administration issued a shutdown notice to the platforms B and C of Penglai oilfield, and said that the two oil spills had been emitting oil flowers for several consecutive days, and there were still floating oil zones in the nearby sea areas. Seabed exploration also found that there were signs of oil spills in the sea areas near platform B

various facts show that most of the oil spill disposal measures taken by ConocoPhillips so far are temporary and remedial, which can not completely and effectively eliminate the risk of oil spill, and the possibility of oil spill again exists at any time

the Marine Supervision and law enforcement personnel stationed on the platform told that after the two drilling platforms were notified by the superior to stop production at noon on the 13th, all operations were stopped at about 3 p.m. However, there are still no specific measures to check the oil spill source and leakage point, only cleaning up the seabed oil-based mud and oil spray on the sea surface of platform C

interviewed Lu Aimin, manager of ConocoPhillips B drilling platform, on the ship "China Marine Surveillance 15". He said that at present, ConocoPhillips has found the oil spill point of platform B and installed an oil containment hood. Now all the oil containment hood and sea surface recovery device receive is water, and there is no oil spill; The oil spray rising near platform C is caused by cleaning up the floating oil spray of seabed oil-based mud. Well C20 where the kick accident occurred has been sealed by cement plug

linfangzhong, deputy chief of the North Sea Corps of China maritime surveillance, pointed out that the oil spill source of platform B is now determined to be from the stratum, but the sea area near platform B is large, and now the location of the oil spill cover is a bulged "bag". It is not clear whether there are such suspected points in the sea area near platform B, and the real oil spill source is not clear. Although the oil spill source and crude oil seepage path are not clear, one thing is clear: the oil spill near platform B is closely related to reinjection pressurization

"at the beginning, ConocoPhillips' report was that 'the proportion of reinjection in GDP (gross domestic product) in 2015 may strive to reach about 8%. Now ConocoPhillips has no further clarification on whether the oil spill accident is completely caused by reinjection pressurization." Lin Fangzhong said, "in addition to cleaning up the seabed oil-based mud, the oil spray emerging from the C platform may also be caused by inadequate sealing measures, such as the blocked cement plug does not completely seal the oil spill point or the formation has other oil spill temperature value points, which are unknown. ConocoPhillips needs to be further investigated, which is what the State Oceanic Administration has been asking ConocoPhillips to do."

in addition, after the State Oceanic Administration issued a shutdown notice to ConocoPhillips and asked it to thoroughly investigate the oil spill source, the North Sea Corps of China Marine Supervision has not received the report of ConocoPhillips organizing relevant experts to investigate the oil spill source, and the on-site law enforcement personnel have not seen that ConocoPhillips has taken corresponding measures to thoroughly investigate the oil spill source

it was learned that after the order to suspend production was issued, the State Oceanic Administration strengthened the supervision of on-site personnel, implemented real-time supervision on the shutdown operation, and ensured that the operation of platforms B and C was completely stopped; Urge ConocoPhillips to take substantive measures to investigate the oil spill source as soon as possible and completely eliminate the hidden danger of oil spill; Clearly require ConocoPhillips to come up with the troubleshooting plan and time schedule; It shall be publicized to the public and subject to the supervision of social and regulatory departments

about 5 minutes after returning from the drilling platform, a red tide zone with a length of two nautical miles was also seen in the sea area near 3 nautical miles from platform B and 2 nautical miles from platform C. Cuiwenlin, director of the North Sea monitoring center of the State Oceanic Administration, told that whether the red tide was caused by the oil spill accident needs further research to determine

at present, the North Sea Branch of the State Oceanic Administration has five marine surveillance ships near the drilling platform, which are responsible for the monitoring and supervision of on-site oil spill disposal, marine ecological investigation and administrative punishment investigation. "At present, the ecological investigation scope has reached 6200 square kilometers, and the sampling monitoring of 242 stations has been completed, including seawater, sediment, marine plankton and benthos." Cui Wenlin said that the investigation of marine ecology will play an important role in the assessment of ecological damage compensation for the oil spill accident

ConocoPhillips announced on the 14th that the oil spill volume of the oil spill accident was 1500 barrels to 2000 barrels, equivalent to 205 tons to 274 tons

Lin Fangzhong said that the amount of oil spilled by the State Oceanic Administration will be determined based on the evidence obtained from the investigation and the on-site monitoring results

in early June this year, oil spills occurred successively on platform B and platform C of Penglai oilfield jointly developed by China National Offshore Oil Corporation and ConocoPhillips China Co., Ltd., a wholly-owned subsidiary of ConocoPhillips. Then, after the water injection and cuttings reinjection of platform B were stopped, the oil spill was basically controlled on June 19; After the cement well sealing measures were taken for platform C, the oil spill was basically controlled on June 21, but there was continuous oil spill

as of July 11, the oil spill accident caused 840 square kilometers of inferior class IV seriously polluted sea water area, and caused about 3400 square kilometers of sea water around the drilling platform to fall from class I water quality to class III and IV water quality
