الوصف

1.Description

The float collar is installed near the bottom of the casing string on which cement plugs land during the primary cementing operation. It typically consists of a short length of casing fitted with a check valve. This device may be a flapper-valve type, a spring-loaded ball valve or other type.

The check-valve assembly fixed within the float collar prevents flowback of the cement slurry when pumping is stopped. Without a float collar, the cement slurry placed in the annulus could U-tube, or reverse flow back into the casing. The greater density of cement slurries than the displacement mud inside the casing causes the U-tube effect.

Advantages:

High strength design ensures high pressure bump and back flow resistance;
Withstands long periods of circulation;
Automatic fill-up, saves considerable running-in time of casing;
Easy drill out with PDC bits;
Special non-rotational groove design ensures cementing plugs dilled out quickly;
Can be used not only in unclassified technical casing, oil layer casing but also in deep well, extra-deep well and special technology well
It is economically priced.

2.Specifications

1) All inner parts are made of easily drillable aluminum alloy
2) The device can be connected directly to same type casing
3) Reliable back-pressure leak proof structure, enable grout or slurry flow with less resistance
4) Valve seat and valve disk can effectively prevent grout from flowing back
5) Hardness of base material is equivalent to API Spec N**0
