摘要
为了解决水平井在超稠油蒸汽吞吐时溢流以及脱抽等问题,通过对目前的注汽管柱、采油管柱、采油泵以及井口进行优化及改进,成功研发了水平井双管柱开采技术,实现了在不动管柱的情况下,可以对蒸汽吞吐井注蒸汽闷井后直接进行采油的目的。该技术既能满足日常的采油要求,又能够保证注蒸汽及采油的安全性,对于现场的推广和应用有重要意义。
In order to solve the problem of overflow and off-pumping in horizontal well for cyclic steam stimulation of extra heavy oil,the double string in horizontal well for thermal recovery technology is developed by optimizing and improving the present steam injection string,production string,wellhead and down hole pump,thus realizing commissioning directly production period after steam soaking period without pulling up the injection string.Field experiment shows the technology can meet the daily production requirements,and also can ensure the safety of stream injection and oil production.It is Worthy of popularization and application.
