蒸汽吞吐注汽过程中井筒径向热损失注主要模型概述

An Overview of Main Models of Mellbore Radial Heat Loss in Steam Injection Process

稠油热采一般采用热力开采,其中最常用的是蒸汽吞吐,即把蒸汽注入油层的加热方式。为了有效地减少其在注汽过程中径向热损失,提高稠油热采效率,需要对注汽过程的能量变化进行理论分析和研究。在已有理论基础上,相继建立了吻和较好的理论模型,为实际生产提供了更多的理论支持。

This is the general use of thermal recovery of heavy oil thermal recovery, which is the most commonly used steam stimulation, as is used in the steam injection heating oil. In order to effectively reduce the radial heat loss in steam injection process, we have improved the efficiency of thermal recovery of heavy oil, the theory analysis and research of. Based on the theories, more theoretical models have been established to provide for actual production.
