Abstract

Based on development of cyclic steam,we used the thermal numerical simulation to do the optimized horizontal technology for the horizontal well spacing and horizontal well section length in the carbonate reservoirs with low permeability and heavy oil.We established four different kinds of numerous models for low permeability and medium viscosity,high permeability and high viscosity,medium permeability and high viscosity,and high permeability and medium viscosity.The production steam\|oil ratio and cumulative oil production was chosen as correlation index.The result shows that the end effect of steam injection does not happen in the heavy oil reservoirs with low permeability and moderate viscosity by horizontal well,which is different in the high permeability and high viscosity reservoirs.In the low permeability and moderate viscosity heavy oil reservoirs,the reasonable well spacing of horizontal wells is 100m,and the horizontal well length rang from 300m to 400m after the optimization.

Key words： Heavy oil reservoir; Cyclic steam stimulation; End effect; Optimization design.
