Rupture Disc Circulating Valve Simulation Test For Fracturing Operation
The RD Circulating Valve is a tool of DST tool string, which can be used in drill stem testing operation and fracturing operation. The annulus pressure made RD burst and the pressure goes into RD hole and push circulating mandrel forward, then open the circulating ports.
The Rupture Disc Circulating Valve is composed of below major sections:
1. The power section consists of a power mandrel case and rupture disk that is available for a wide range of pressure applications. The rupture disk bursts at a predetermined pressure, allowing annulus pressure to be applied to a differential area on the power mandrel. The power mandrel moves down, first pushing the ball valve closed, and then opening a set of circulating ports.
2. The circulating section consists of a set of ports that are initially sealed by the power mandrel. When the rupture disk bursts, the power mandrel moves down, exposing the ports that allow communication between the annulus and workstring.
RD Circulating Valve Simulation Test For Fracutring operation
|Equipment set up|
|1||1) 45-60 deg deviated direction
2) Closed-end of RDCV with test cap/plug and apply pressure to simulate differential pressure
3) Burst the rupture disc to activate the valve Acceptable Range of burst pressure: +/- 300 psi (7.5ksi burst rating is the max rating selection)
Fully fill with proppant 20/40 + Brine( 6PPA) inside the circulating valve, fill with water and apply pressure to 7,500 psi. Using 5.5K rupture disc rating and perform valve open function under mentioned condition.
Note: Fluid pressure applied on Rupture Disc.
