摘要： 关井焖井是稠油油藏蒸汽吞吐开采中的一个必要环节。长期以来,人们对于焖井时间的确定主要依靠现场的经验,没有一个可靠的理论依据。另外,对焖井时间与加热带大小影响的认识也比较模糊。应用油藏工程、热传递基本理论剖析了焖井过程中油层和蒸汽的能量变化,推导出确定合理焖井时间的计算公式和焖井结束后加热半径的计算公式。这对重新认识焖井过程有积极的理论意义。

关键词: 蒸汽吞吐, 开采, 焖井时间

Abstract: Shut-in for soaking is an indispensable process during steam stimulation. For a long period of time, the determination of soak time relies on field experiences without a theoretic basis. In addition, the effect of soak time on heated radius is not well understood. This paper presents the calculation formula for determination of reasonable soak time and heated radius at end of soaking by analysis of changes of oil layer and steam energy during soaking period, based on basic theories of reservoir engineering and heat transfer. This new consideration is of positive theoretical meaning to re-understand the steam-soak process.

Key words: steam stimulation, exploitation, soak time
