Method of numerical analog is discussed.A set of equations is worked out co- nsidering the thickness ,heterogeneity,temperature and rock mechanics of the res- ervoirs,and integrating filtration mechanics with rock mechanics.Despite the co- mplicate nature of the equations,non-linearity of unknown functions and presence of unknown boundaries(fractures),the finite element method for alternating solu- tions has been applied with success and satisfactory results obtained in calculation. Also discussed are the opening of fractures in reservoirs nearby the bottom of injection wells,size of fractures,contribution of fractures to the absorbability of reservoirs and interferences between the multi-fractured zones etc.in respect to the application of the method in sandstone reservoirs under high-pressure water flooding.Clarification of all these problems may help determine a reasonable range of water-flooding pressure.

Heaters with feed and air preheated by hot flue gas and hot residue oil respectively have attracted extensive attention. Method for heater design calculation is proposed. It includes equations for calculating the related parameters, convection and radiation sections, and residue oil-air heat exchangers.

The performance of heater with both feed and air preheated was described. Heat efficency was always above 85% during operation. The preheater did not exert its full capability due to the leakage at heater bottom, though all other main equipments went very well. An equation was derived for calculating the"gross heat efficiency"for leakage control.
