Well Testing Pump Thru Rupture Disc RD Circulating Valve 5" 15000 PSI
Overview of Pump Thru Rupture Disc Safety Circulating Valve
The Pump Thru Rupture Disc Safety Circulating Valve is a kind of RD circulating valve, used for the drill stem testing operation in cased hole well testing service. he Pump Thru Rupture Disc (RD) safety circulating valve is with two functions, one is safety valve service, the other is circulating valve service. The RD circulating valve is with pump thru capabilities.
The pump thru rupture disc safety circulating valve is operated by increasing the applied annulus pressure so that the annulus pressure at the tool reaches a predetermined value at which point the RD will burst.
Constructure of the RD Safety Circulating Valve
The Pump Thru Rupture Disc Safety Circulating Valve is composed of power section, circulating section and safety valve
* The power section consists of a power mandrel, an Rupture disc case, and Rupture Disc.
* The circulating section consists of a set of annulus ports in a case that is initially sealed by the power
* The safety valve consists of a sleeve, flapper valve, and seat.
Rupture Disc of Pump Thru RD safety circulating valve
Before using the Pump Thru RD safety circulating valve, it must determine the operating pressure. According to this pressure, the proper Rupture Disc will be selected with the necessary pressure rating. To confirm the operating pressure for the pump thru RD safety circulating valve, it requires the data of mud weight, true vertical depth of the valve, bottomhole temperature, and maximum allowable annulus pressure.
