| Abstract: | A two layer geological model is established to study the problem of layer steam injection allocation in single well of viscous oil reservoir with heterogeneity layer. Coordination calculation for the flow in pipe, nozzle and reservoir, critical flow characteristics through the throttling jet are studied. Sound injection profile is obtained with the reduced operation cost in single well. The selection principles of steam allocation rate, steam injection rate and the structure of nozzle are discussed. Application of layer steam injection in oilfield shows a good result. |
