2011年中国石油需求同比增速将降至2%，达83亿吨；成品油消费量将达57亿吨，增长3%；汽油供略大于求，柴油则总体偏紧。 2010年中国石油表观消费量为55亿吨，同比增长4%。原油表观消费量首次突破4亿吨，达到39亿吨，增速高达1%。国内原油产量首次突破2亿吨，同比增长5%以上，为十五年来最快。受多重因素影响，2011年我国石油需求增速将下降，预计全年石油需求量为83亿吨，增长2%；原油需求量71亿吨，增长2%。In 2011， China's oil demand year-on-year growth will drop to 2% to 483 million tons; Product oil consumption will reach 257 million tons， up 3%; For gasoline， diesel is slightly higher than for the overall In 2010 China petroleum apparent consumption for 455 million tons， an increase of 4% Crude oil apparent consumption the first time exceeded 400 million tons to 439 million tons， the growth rate as high as 1% Domestic oil production first breakthrough 200 million tons， an increase of 5% or more， for 15 years By multiple factors， in 2011 China's oil demand growth will fall， the year is expected to petroleum demand for 483 million tons， up 2%; Crude oil demand for 471 million tons， an increase of 2% 参考资料：羊城晚报多媒体数字报刊平台
Abstract: At present， produces one to use the manual chemical examination the method to examine uses the note boiler furnace hotly the movement situation， this method has the big personal error and the hysteresis quality， has to a great extent affected the note steam dryness test In order to solve this problem， picks the craft necessary technology hotly along with the thick oil the development， the water/steam two phase current dynamic monitor technology development， appeared two phase current microcomputer observation and control Two phase current microcomputer observation and control technology is with the standard throttling gear measured two phase currents dryness and the current capacity， and summarize a new technology take this as the foundation which and develops， may survey each note steam parameter effectively， automatic detection note boiler furnace movement At the same time， its concise direct-viewing man-machine contact surface， may satisfy the field use request Key word: Two phase currents; Note steam parameter; Note boiler furnace; Dryness; Current capacity
Abstract: At present， the production line used for testing the method of artificial heat boiler using steam injection operation， this method there is a large man-made error and lag， to a large extent affected the dry steam injection test accuracy In order to solve this problem， with the heavy oil thermal recovery process supporting technology development， water / steam two-phase flow of the dynamic monitoring of technological development， there has been two-phase flow computer measurement and control Computer technology is a two-phase flow measurement and control expenditure by standard two-phase flow measurement device with the flow of dry degrees as the basis for the summary and the development of a new technology can be effectively measured parameters of the steam injection， steam injection automatic detection the operation of the At the same time， its simple and intuitive man-machine interface， can be used to meet the requirements of the Key words: two-phase flow; steam injection parameters; boiler steam injection; stem degrees; flow
