1. Description

Casing float shoe is an improved product developed by ourselves based on the modern technique domestic and abroad. The component of the equipment is drillable aluminium alloy which enables the product the advantage of special configuration high tensity, light, strong pressure bearing, and good air proof capability. Therefore, it can be applied widely, not only in unclassifed technical csing, oil layer casing, but also in deep well, extra-deep well and special technology well.

2.Characteristics

 

1)High strength design ensures high pressure bump and back flow resistance;

 

2)Withstands long periods of circulation;

 

3)Automatic fill-up, saves considerable running-in time of casing;

 

4)Easy drill out with PDC bits;

 

5)Special non-rotational groove design ensures cementing plugs drilled out quickly;

 

6)It's econmically priced

3. 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-80
