Multi Cycle Downhole Oil Tools OMNI Valve Downhole Well Testing
Equipment
Introudction of Multi Cycle Circulating Valve Test
Multi Cycle Circulating Valve is annulus pressure-operated
re-closable circulating valve with the full bore, it is named OMNI
valve in Halliburton, the circulating valve is worked for the
formation testing in cased hole, oil tube tradition perforating
tube string testing and cycle operation in the conjunction of
perforation and full-opening formation testing.
Specification of Multi-cycle circulating valve
| Nominal Size /in. | OD /in. | ID /in. | Thread Connections | Length /in. | Working Pressure |
| 3 7/8 | 3.9 | 2 | 2 7/8 CAS | 30.13 | 15000 psi |

Pressure and Function Test requirement and procedure
Test Equipment Requirement :
* One hydraulic pump: 5L/1Minute, work pressure should be above
20000PSI.
* One nitrogen pump: Work pressure should be above 10000PSI.
* Air compressor: Work pressure should be above 150PSI (1MPa).
* Power, clamp, test caps, test pulling caps, pressure gauge, box
spanner, pressure collection system
and related high-handed pipe, sensor, computer, printer
OMNI Valve Test Condition:
* No sands and dust in the place of production depositary.
* Temperature:0~35℃
HSE Safety instructions:
*Only 20# silicone oil allow to use as lubricating oil when the
nitrogen chamber works.
* Purity requirement for nitrogen is above 99.9%.
* When running each pressure test, you must increase pressure
gradually. When the pressure is up to
20MPa, hold on for one minute, then every 10MPa keep it for one
minute until the rating pressure;
* During doing the pressure test, the tool should be placed in the
test pit and cover the protecting board
on the pressure test plug.
