Drill stem testing OMNI valve

Introduction of the OMNI Valve

OMIN Vale is acceptable 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. It 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.

Working principle of OMNI Valve

OMNI circulating valve completes the function by increasing and releasing the annulus pressure .

According to the construction features it can be learned when increasing the annulus pressure, the piston push the hydraulic oil to move to the left, and the hydraulic oil push the check valve assemblies to move to the left until to the upper dead point, then the hydraulic oil pass the passageway and push the floating piston in the nitrogen chamber, thus the pressure is saved in the nitrogen chamber.

When releasing the pressure, because the pressure in nitrogen chamber is above the annulus

pressure ,the nitrogen pressure push the floating piston in the nitrogen chamber and then to hydraulic oil move to the right, the check valve assemblies to move to the right under pushing of hydraulic oil until

to the lower dead point, the hydraulic oil make the nitrogen pressure equal to the annulus pressure.
