| 摘 要： | 提出了在蒸汽辅助重力泄油自喷生产条件下,用视密度代替ts值判断现场生产状态的方法,并从理论计算和实际数据分析两方面对其基本原理作了阐述。该方法只要求有井下某点的压力测试数据,便可以结合井口油压数据,估算出井筒视密度,从而实现等同于ts值的生产状态判断功能,计算简便,更具实用性。该方法在先导试验区的实际应用表明,对于现场生产调控具有较好的指导作用。

| Abstract: | Subcool is a conventional parameter,by which we can diagnose the state of steam assisted gravity drainage(SAGD) production,but this method extremely relies on the monitoring of temperature and pressure in wellbore.According to this,a new simplified method for the state diagnosing work is proposed,which can be a substitution for using the conventional subcool parameter.In the case study,just by using pressure in downhole and oil pressure at wellhead,the wellbore apparent density can be calculated in conditio... |
