和生产井，其设置为从烃层中汇合的排出通道收集和生产运动流体。
A generating well collects and generates the movement fluid from the discharge channels in the hydrocarbon layer.
该液体排出通道沿轴延伸且关于该轴形成非对称的开口，以提供液体细丝沿所期望方向的受控运动。
The liquid discharge passage extends along an axis and the opening is shaped asymmetrically about the axis to provide a controlled directional movement of the liquid filament in a desired direction.
该非对称形状可以单独或组合使用与该液体排出通道相交的凹槽、斜面或阶梯部分来形成，或采取其它方式来形成。
The asymmetric shape may be formed by a notch or a chamfer or a stepped portion intersecting with the liquid discharge passage, or combinations of these features, or in other manners.
