Study on injection and production parameters of steam soak for horizontal well of super-heavy oil reservoir in Chun-10 well-block

Main oil layers of N1S1II2 and N1S1II1 of well-block Chun 10 in Chunguang Oilfield has complicated geological features.During the process of steam soak,there was no reasonable and effective method to provide guidance for choosing injection and production parameters and therefore it hindered the improvement of economic benefits.Aiming at the above problem,the geological model which is suitable for the optimization of injection and production parameters in horizontal well has been established.Based on this geological model,the optimum injection-production parameters of different wells which have different location and layer series of development has been confirmed by numerical simulation and it can be used for choosing injection and production parameters of steam soak.
