一种SAGD水平井系统
摘要：
本发明提供了一种SAGD水平井系统。该SAGD水平井系统包括两个水平井，且两个水平井为上水平井和下水平井，SAGD水平井系统还包括蒸汽控制装置，该蒸汽控制装置包括：蒸汽供应装置；第一输送管路，上水平井和下水平井之一通过第一输送管路与蒸汽供应装置相连通，第一输送管路上设置有第一流量计和第一电动调节阀。上水平井或下水平井通过第一输送管路与蒸汽供应装置相连通，可以实现对注入水平井中蒸汽量的控制，即通过蒸汽控制装置实现了准确的注气计量，在满足待开采原油所需的热量的前提下，并没有造成过多蒸汽量的浪费，进一步提高了生产单元的净利润。
摘要（英）：

The invention provides a SAGD horizontal well system comprising two horizontal wells; the two horizontal wells comprise an upper horizontal well and a lower horizontal well; the SAGD horizontal well system also comprises a steam control device; the steam control device comprises a steam supply unit and a first convey pipe; either the upper or the lower horizontal well is connected with the steam supply unit through the first convey pipe; the first convey pipe is provided with a first flow gauge and a first electric control valve; the upper or lower horizontal well is connected with the steam supply unit through the first convey pipe, so the steam quantity injected in the horizontal well can be controlled; the steam control device can realize accurate steam injection measurement, so too much steam waste can be prevented while ensuring the heat demands of to be mined crude oil, thus further improving production unit net margin.
