large drift diameter composite bridge plugs

large drift diameter composite bridge plugs


Composite Drillable Bridge Plug can be made according to well condition. It has high drillability and used 
Together with the sand and cement, leaving no fragment in well after drilling and plugging. After filling sand and cement, 

It is mainly used in the oil, gas and water layer for temporary or permanent block, concrete can fit for the production of shaft seal, water plugging and fracturing, acidification , testing etc  construction. Conditions.


Testing

1. All the tools will be tested strictly before shipment. The testing will be with material loading and full-load operation for at least one shift. 

2. Qualified successful before get in your warehouse. 

Components

All the key parts such as hydraulic system, electric parts, and valves are the best brand from domestic, also other material can be offered according to your requirements. 

Packing

Packed in wooden cases, to ensure the integrity and security of the machine.
