Based on literature research, the pressure distribution and air leakage through building enclosure is discussed as a result of chimney effect.

Because of long-term development of maturing fields and development of logging tools,there is a big difference between the same kind of logging curves in the same stratum of the same oilfield,which has great effect on establishment of the air permeability interpretation model.

Using the known relationship f ormula and charts of technical recovery reserve's economic conversion ratio of d eveloped oilfields and reserve air permeability, new .

At present, China has no national standard of Anode's air permeability, and the International standard is strict with it,taking America anode for example this paper,discusses the effect of the pitch content on physicochemistry index of carbo brush by changing the pitch content.

Analysis of air permeability errors of building curtain walls test devices;
