Donwhole Tester Valve LPR-N Valve 5" x 15000psi For Oil Well Testing
The LPR- N Tester Valve is a kind of downhole tester valve used in oil well testing service. The LPR-N valve is a full-opening, annulus pressure-operated valve. The tester valve permits measuring multiple closed-in pressures in cased holes where pipe manipulation is restricted and a full-opening string is required.
The nitrogen chamber of LPR-N valve is charged at the surface to a selected pressure determined by surface temperature and bottomhole temperature and pressure.
The ball valve on the tester valve operates independently of internal pressure changes, like with acidizing or fracturing operations, no need special bypass tools, but if a production packer is used, the pressure will transfer to formation directly if no bypass tool involved.
