在解决循环漏失问题时，由絮片材料或纤维材料配制的堵漏小段塞被设计用于封堵射孔孔眼或漏失流体的层段。
In counteracting lost-circulation problems, a lost-circulation pill prepared with flaked or fibrous material is designed to plug the perforations or formation interval losing the fluid.
所配制的流体小段塞功能繁多，如用于围绕井筒进行循环并将碎片或井筒填充物带出井筒的在高粘度下配制的驱扫小段塞。
Fluid pills are commonly prepared for a variety of special functions, such as a sweep pill prepared at high viscosity to circulate around the wellbore and pick up debris or wellbore fill.
段塞的位置应能确保流体在油管柱从井筒中起出时从油管柱中自然地放泄。
A slug may be placed to ensure that fluids are naturally drained from a tubing string as it is pulled from the wellbore.
这也允许围绕阀塞的冲刷流体介质的循环。
This also permits circulation of a flushing medium around the plug.
当需要清洗时，旋开主管底部螺塞，排净流体，拆卸法兰盖，取出滤篮，清洗后重新装入即可，因此，使用维护极为方便。
When cleaning, unscrew the head bottom plug, drain fluid, remove the flange cover, remove the filter basket, cleaning and re load can, therefore, maintenance is extremely easy to use.
当阀塞离开阀座位置时，被压缩的清洗流体介质变成冲刷流体介质，实现冲刷作用。
The flushing action is achieved as the compressed purge media is released to become the flush media when the plug unseats .
可以使用管道塞，轻松关闭流体循环通过防液渗微型连接器进行电气连接使用新的无螺纹？
Pipe plugs can be used to easily shut off recirculation Electrical connection via liquid-tight miniature connector Uses new threadless?
所述防溢出手术入口塞使得医生在关节内窥镜手术中从手术区域周围的软组织中排出多余流体。
The anti-extravasation surgical portal plug allows a surgeon to drain excess fluids from the soft tissue surrounding the surgical field during arthroscopic surgical procedures.
楔塞结构的其他内在优点是只有当阀门开启或关闭时才会消耗清洗流体介质。
Another benefit inherent in the Wedgeplug design is that the purge media is only consumed when the valve is being opened or closed.
基于流体质量、动量守恒导出了单管球塞气举和分体式柱塞气举采用“压低液面”卸载的数学模型；
Based on the mass and momentum conservations of fluid, the mathematical model of Two-Piece plunger lift and single-string pig lift which unload by pressing fluid level down is derived.
②凝胶ZND是否能够形成隔断地层流体与井筒流体联系的隔断式凝胶段塞，所形成的凝胶段塞是否具有启动压力梯度及其调控措施仍需实验和现场试验证实；
However, it was still lack of systematic study of rheology of gel ZND. And the rationality, correctness and feasibility of the separating-type gel slug principle need to be verified yet.
