Tool Introduction

OMNI circulation valve is a type of annular pressure control with the ability to repeatedly switch on and off the operating pressure without changing with well depth and temperature. It can be used for acidizing, fracturing and other stimulation measures.

Structural characteristics

① It can achieve multiple cycles and downhole shut in;

② The operating pressure is not affected by changes in well depth and temperature;

③ When drilling, the circulation valve can be set in different states (testing, cycling) according to actual needs; ④ The use of this valve can simplify the program of multiple operations and greatly reduce exploration costs;

operation

During the testing process, the OMNI valve is in the testing position. During the cycle, the annulus is repeatedly pressurized and depressurized. The OMNI valve switches from the testing position to the transition position, and then from the transition position to the circulation position to perform the well killing cycle. Repeat the above operation to achieve the transition between different positions.
