| Abstract: | The energy equation and heat conduction equation in boreholes are developed, with gas-liquid two-phase flow, heat transfer, and the dynamic balance theories. The authors found an expression to describe the relation between the cross-sectional area of steam injector hole and the layer pressure. With this expression, a new method was used to design the main parameters of a steam injector. The actual measurement data show that the theory provides a firm foundation for the design of self-adjustable layered steam injectors and mathematical models of engineering analysis on layer steam injection. A new-style self-regulation steam injector is designed, and it is realized to fix the proportion of injected steam. |
