Brief introduction

OMNI circulating valve is a full opening, annulus pressure-operated re-closable circulating valve which can be open and closed many times. The tool is operated by repeatedly cycling the annulus pressure up to a predetermined value and then releasing this pressure.

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. 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.

OMNI circulating valve has two kinds: 3 7/8″ and 5″. They all can run in subsurface environment which contains acid.

Working principle

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.
