TIANJIN， Feb． 22 （Xinhua） －－ China＇s largest crude oil producer， Bohai Oilfield， has exceeded 90，000 tonnes of daily crude oil production since January， marking the first time the oilfield has surpassed this benchmark， its operator said．

＂This is equivalent to one－sixth of the country＇s daily crude oil production and a new record in the history of the Bohai Oilfield，＂ said Zheng Xu， deputy manager of the production department of the Tianjin branch of CNOOC China Limited．
