Downhole Testing Multi Cycle Circulating Valve 5" x 15000 psi
DST OMNI Valve Multi Cycle Circulating Valve High Pressure Drill Stem Testing
Where are the OMNI Valve used ?
OMIN Vale is the multi cycle circulating valve applied for the full-opening formation testing in cased
hole, oil tube tradition perforation, tube string testing and cycle operation in the conjunction of
perforation and full-opening formation testing.
Features of the Multi cycle circulating valve
The OMNI valve overcomes the shortcomings of some other circulating valve, at a certain position, can
use the annulus pressure to operate other tools many times and there is no influence upon the OMNI
circulating valve. Because of the ability of opening and closing the well many times, it can carry on
acidification and fracturing etc. other well stimulations in the end of the full-opening formation test.
Using the valve can make the test program simple and reduce the reconnoitering cost greatly.
