Abstract: The annual consuption of crude oil at present in our Bureau is over 320 thousand ton. In Oder to inprove the energy structure in heat transportation technology, a consideration has been presented which is gradually use of replacement of crude oil with residuals at heating and pumping station if possible. It is practical theough the comparison of physical properties between crude oil and residuais. In view of variety of oil taken in the paper the teatures of different methods of oil taken (installation of simple distillation devices, equal heat macc exchange, crude oil processing) are analysed, the best way is oil taken according to the equal heat value method in accorddance with the principle of crude oil consuption not being increased. Based on the consideration of current economic policy a series of economic methods are stated and the economic benefit are predicted if Daqing oil taken as an example.
