| Abstract: | Models for the calculation of temperature and pressure distribution along the wellbore based on the theory of two-phase flow and heat transfer and a computer program is written to accomplish the calculation.The injection coeffients affect the efficiency of steam injecting heat exploiting was systemetically analyzed and the findings are that mass velocity and dreness fraction of the steam are tow main factors affect the efficiency of steam injection and these findings provide theoretical foundation for the option of steam injecting heat exploiting. |
