Applications
* Drainage of tubing string
* Prevention of pulling wet tubingFeatures
* Available for both standard and high temperature applications
* Compact design allows rapid installation with power tongs
* Torque Ring compatible when no-turn tools aren’t run
* Industry leading thread treatment for prolonged run life
* Box by Pin construction
* Viton seals
Benefits
* Calibrated brass shear screws provide consistent shear values and reduce wear on steel parts, permitting multiple reuse
* Beveled edges on top and bottom speed up running and pulling tubing, especially when casing patches or other issues are present
* Multiple rebuilds allowed, reducing total cost of ownership
The Operation Principle
Oil Drain Device is connected to the lower part of the pump barrel and the upper part of fixed valve or the upper part of the pump tubing, which goes with a pump into the well production. At the next pump inspecting operation, remove the sucker rod, cut copper pin from the wellhead with the sucker rod pup joint , which will connect the tubing and casing. Oil drainage main body cone can be used as a single flow valve in the operation of fracturing, acidizing and channeling.The ball will be washed out after backwashing wells so that avoid spraying and extracting the tool that may cause environmental pollution.
