| Abstract: | In drillstem test,APR-A circulating valve, rupture disc circulating valve, impact reverse circulating valve are allsingle acting circulating valves with circulating ports kept unclosed once they are opened,while the circulatingports of OMNI valve may be opened and closed as many times as required, through which the operations such askilling the well by circulation,spotting fluid cushion and pressure testing of work string are possible. This papersimply describes the specifications, structure,working principle and cycling process of OMNI circulating valve. |
