Brief of LPR-N Valve

 

The LPR - N Valve is the tester valve with a full bore feature, the LPR -N valve is annulus pressure-operated valve. The LPR-N Valve is used in cased holes to measure multiple closed-in pressures  where pipe manipulation is restricted and a full-opening string is required. The nitrogen chamber of the LPR-N valve is charged at the surface to a selected pressure determined by surface temperature,bottomhole temperature, and bottomhole pressure. It is served as the master tester valve in drill stem testing operation. 

 

Structure of the LPR-N Valve

 

Tester valve consists of Ball valve section, Power section and Metering Section.

 

* Ball valve section

 

The ball valve section contains the ball valve and related mechanical components that rotate the ball.
When the tool is activated, the ball is rotated to the open position, allowing the reservoir to flow into the
test string

 

* Power/nitrogen section

 

The power/nitrogen section contains the shear pins, operating piston, and nitrogen chamber. In the power
section, one side of the piston is exposed to annulus pressure, and the other is exposed to pressurized
nitrogen, which acts as a large gaseous spring.

 

* Metering section

 

The metering section of the LPR- N Valve is isolated from the annulus fluid by an oil and floating piston barrier to control the rate of pressure change.
