| Abstract: |
| Non-piston steam displacement model was established based on steam channeling performance and steam condensate for steam stimulation wells. The calculation methods of cummunication degree and channeling angle of inter-well formation were proposed according' to differential reservoir property, and directional steam flow rate could be obtained. The steam sweep volume and pore size could be also determined. The numerical simulation shows that the maximum steam sweep efficiency can be gotten for the profile control agent slug at a half inter-well distance and with slug size of 10% ? 15% steam sweep porous volume. The profile control parameters of LI833 well group were designed and the profile control particles diameters were selected according to deeply profile control principle. The volume of slug is 32 m3. The changes of temperature and water cut are regular and the phenomenon of steam channeling around production wells does not occur after field application. |
