Oil Well Downhole Testing Rupture Disk Safety Circulating Valve Full H2S

 

The rupture disk (RD) safety circulating valve is the component of the DST toolstring, with  the functions of  both a safety valve and circulating valve. The RD safety circulating valve workes as a safety valve when the annulus pressure reaches a predetermined value. At that pressure, the valve isolates the workstring below the tool and establishes communication between the annulus and the workstring above the tool. The Rupture Disk Circulating Valve can be converted into a circulating valve when the ball valve section is removed and attach a lower adapter called RD Circulating Valve.

The valve can not be open when closed in downhole operation. RD Circulating valve is the same as RD Safety circulating valve except short of ball valve section, the annulus pressure made RD burst and the pressure goes into RD hole and push circulating mandrel forward, then open the circulating ports.

 

The RD circulating valve is composed of three 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.

3. The safety valve consists of a ball valve, operating pins, and collet fingers. As the power mandrel moves down, the operating arms close the ball valve. The collet fingers expand, allowing the power mandrel to continue traveling down to open the circulating ports
