摘要

讨论了超稠油油藏水平井蒸汽循环预热开采的热力计算问题,分析计算了3种循环管柱结构对油层加热效果的影响,同时对蒸汽的循环流量进行了筛选,计算了预热时油层温度场随预热时间的变化,最后推荐了水平井蒸汽锅环开采超稠原油的循环管柱、循环流量和循环预热时间。

Abstract

This paper discusses the thermo calculation problems during steam heating for horizontal well of viscous oil reservoir,analyses the effects of three cycle pipe strings on heating oil formation,selects the flow rate of steam,and calculates the variation of formation temperature field with heating time.It recommends the cycle pipe string,flow rate and heating time of horizontal well for super viscous oil.
