Primary Investigation About The Environmental Impact Reevaluation Of Oilfield In Beibu Gulf

In order to strengthen the environment protection which effected by the reconnaissance and exploitation of the oil in ocean, and make the reevaluation of the environmental infection standardization, the State Oceanic Administration constituted Temporarily Management Stipulate of Marine Petroleum Exploitation Reevaluation based on Marine Environment Protection Law of China and the Environment Impact Assessment Law of China. The emphases assessment area of the environment impact reevaluation of marine petroleum exploitation must be the dilution zone of pollution and the area nearby oil platform; The emphases content of assessment must be the run situation of the environment protecting establishment, the situation about the pollution discharge, the effect of pollution prevention and cure, effect degree about the marine environment caused by marine petroleum exploitation.Some conclusions of the environment impact reevaluation of oilfield in Beibu Gluf have been listed:(l)The emphases of the oilfield pollution protection is oil overflow meet an emergency. The renewed Oil Overflow Meet An Emergency Plan is applying for approbation.Now the oil platform W12-1A is implement Oil Overflow Meet An Emergency Plan of Weizhou Oilfield which written in 1998. The on watch boat Nanhai 203 never equiped Oil Spill Chemical Dispersants GMS-2 for 20 barrels and never equiped 9-meters long Oil Spill Chemical Dispersants insufflation pipe. The expert of Zhanjiang filiale explained the Oil Spill Chemical Dispersants were placed in terminal disposal factory in Weizhou island. We suggested that Zhanjiang filiale should communicate with the governor of government to resolve or equip there things on boat according to the ordain.(2)The surface layer sediment in the north area which 500 meters far away from W12-1A was on a strong reductive environment. Some contents of contaminations were very high. The expert of Zhanjiang filiale explained that this area the sulfureted hydrogen was enriched. We suggest that the range about this area must be investigated clearly. The drill fragment which poured on benthal made a serious effect on zoobenthos. Around the contaminant source area the drill fragments covered the benthal like a carpet made these areas without oxygen. Poisonous sulfid was make out by benthal sediment and some zoobenthos had been deracinate(Karl-Heinz Van Bernem). Only when drill is stopped and the oilfield is putted into production the organisms can be detected. In the moderate impact area only after 2 or 3 years can large zoobenthos maybe come back.(3)The hole for sampling has never been setted at the infall of waste water disposal system, and the efficiency of the disposal system can not be analysed.
