双级注水泥器附件

  STAGE CEMENTER PLUG SYSTEM
 
MSC-A型和HSC-A型双级注水泥器附件包括:挠性塞、重力型打开塞(简称重力塞)、关闭塞、碰压座、顶替型打开塞(简称顶替塞)。这些零件由胶塞及铝合金材料制成,均具有良好的可钻性。
 
关闭塞
Closing Plug
 

The accessories of MSC/HSC Stage Cementer include a first-stage plug, free-fall opening plug, closing plug, shut-off baffle and pumping-down opening plug. Being made of rubber or aluminum, these parts are drillable.

 
 
1、碰压座用于挠性塞碰压,一般放置于浮箍以上的一根套管接箍中。
2、挠性塞用于隔离水泥浆和钻井液,第一级替量到位后,形成碰压。
3、重力塞为流线形,内部装有铅,投塞后快速自由下落至下滑套上并形成密封。憋压后打开循环孔。

4、关闭塞用于隔离第二级水泥浆钻井液,当其运行至上滑套位置时形成密封。继续加压,关闭套下行,循环孔关闭。

5、顶替型打开塞用于连续式双级注水泥作业,也适用与在斜井中使用。它可直接打开循环孔,而不像重力塞那样需要较长等待下落时间。
 
1. The shut-off baffle is installed in the casing collar, one joint above the float collar.

First-Stage Plug
 

The first-stage plug is used to isolate the first-stage cement and drilling fluid. On the end of displacement,the first-stage plug lands and effects a seal against the shut-off baffle.

3. Featuring streamline shape and filled with lead, the free-fall opening plug can quickly free-fall to the lower sliding sleeve. When pressure is applied to the casing, it can open the circulation ports.

4. The closing plug is used to isolate the second-stage cement and drilling fluid. When running to the upper sliding sleeve, it effect a seal in the stage cementer. Pressure is applied to the casing and the circulation ports are closed.

5. The pump-down opening plug is used for continuous cementing operation and in deviated wells. It can open the circulation ports directly and quickly, whereas the free-fall opening plug needs longer time waiting for falling.
