摘要
根据多油层层间热干扰、多吞吐周期剩余热量以及注汽过程中的蒸汽超覆等问题,建立了完善的蒸汽吞吐解析模型,并提出由油层平均温度计算井底流体温度的方法,为了预测蒸汽吞吐井产能,提出了不同采出程度阶段下流入动态关系的处理方法,编制了相应的计算软件,结合洼38断块蒸汽吞吐热采实际,在历史拟合基础上优选出注汽参数和多吞吐周期注汽方案,为洼38断块稠油整体吞吐开发提供决策理论依据.
A perfect steam soak predictive model is estiblished with consideration ofheat transfer in multi- layer,heat left in multi-cycle and steam overlay. In order to predictthe productivity of steam soak,this paper presents a method for calculating wellbore liquidtemperature by using the average reservoir temperature and inflow performance relationship(IPR)in different recovery stages. The corresponding computer program was developed.Anoptimum multi- cycle steam injection program was obtained for Wa 38 oilfield on the basis ofhistory matching. A theoretical basis is given for the thermal recovery of Wa 38 oilfield.
