1. Brief Introduction
a). Excessive injection of cement at one shot.
b). The formation cannot bear the gigantic fluid pressure. 
c). Pack off special strata. 
d). Avoid the occurrence of annual air channeling after the cementing job.
e). The considerable temperature difference between the upper and lower section 
makes it rather difficult to adjust the slurry performance.
f). Two-stage cementing for deviated and horizontal wells
 
2. Structure 
Model PYZS-A hydraulic stage tool mainly consists of two-stage coupling (body), 
shut-off baffle, first-stage plug and closing plug.
 
3.Product Features
a). Anti rotation device is designed to prevent the synchronous rotation of closing sleeve and bits.  
b). A particular structure is developed to prevent the possible pre-shutoff of closing 
sleeve.
c). In the closing sleeve of closed circulation hole, close the locking mechanism to 
prevent closure put on the back, to achieve permanent closure. 
d). All accessories, made of premium quality rubber or aluminum material, have 
very good anti-rotating mechanism that makes drill out easily. 
e). Free-fall opening plug and pumping-down opening plug are available to achieve 
mechanical opening. 
f). The I.D. of upper/lower sub should be the same as that of casing, but smaller than 
that of closing sleeve, which protects the closing sleeve.
