    • The present disclosure provides a backflow collection system 500 and a method for reclaiming backflow from a wellbore. The backflow collection system, in one embodiment, includes a collection vessel 520 having an upper section 523 and a lower section 528, the collection vessel having a side opening 530 configured to receive backflow from an oil/gas well, as well as a discharge port 535 proximate an upper end of the upper section configured to discharge pressurized gas from the collection vessel. The backflow collection system, in this embodiment, further includes an auger 560 coupled proximate the lower section of the collection vessel, the auger configured to receive solid and liquid matter from a bottom opening in the lower section of the collection vessel, and when elevated remove at least a portion of the solid and liquid matter from the collection vessel, the collection vessel designed such that when fluid is contained therein it acts as a liquid/gas seal to prevent the pressurized gas from exiting through the bottom opening in the lower section of the collection vessel.
    • 本公开提供了回流收集系统500和用于从井眼回收回流的方法。 在一个实施例中,回流收集系统包括具有上部523和下部528的收集容器520,收集容器具有构造成接收来自油/气井的回流的侧开口530以及排出口 535,其接近上部的上端,构造成从收集容器排出加压气体。 在该实施例中,回流收集系统还包括邻近收集容器的下部分连接的螺旋推运器560,螺旋推进器构造成从收集容器的下部中的底部开口接收固体和液体物质,并且当升高移除时 来自收集容器的固体和液体物质的至少一部分,收集容器设计成使得当其中容纳流体时,其用作液体/气体密封件,以防止加压气体通过下部的底部开口离开 收集船。
